How much difference, in terms of ballistics, is between the 270 Winchester, 270 WSM and 270 Weatherby?

Let’s compare the ballistics of each 270 cartridge by firing a 130gr bullet. We’ll select a factory round and zero each load at 100 yards. Here is the ballistics trajectory graph:

Blue Line – 270 Winchester

Red Line – 270 WSM

Green Line – 270 Weatherby Magnum

Out to 250 yards:

The 270 Winchester firing a 130gr bullet at 3060fps is 6.5″ low

The 270 WSM is 5.2″ low at the same distance.

The 270 Weatherby Magnum is 4.9″ low at the same distance.

Between the 270 Winchester and 270 Weatherby Magnum, the difference is only 1.6″. Under typical hunting conditions this difference is not noticeable. And remember that most shots are taken under 200 yards at deer.

IF you shoot on the open plains where distances of 400+ yards is the norm, then using a WSM or Weatherby in 270 cal makes more sense. But for most hunters the 270 Winchester does the job, and without excessive muzzle blast, recoil, etc.

Which Bullet Produces the best ballistics in the 270 Winchester for Whitetail deer?

For whitetail deer 270 bullets in the 130gr weight class not only have a high ballistic coefficient but shoot accurately in many different firearm makes/models. This combination, when pushed at velocities near 3000 fps makes the 270 Winchester produce ballistics that is ideal for long range shots at deer (300 yards plus).

If hunting larger sized deer like elk you should consider a tougher constructed bullet of 150grs and above. Barnes, Woodleigh and Fail Safe bullets are good examples.

Handloaders – Which Powder produces the best ballistics/accuracy for the 270′s?

Slow burning powder such as IMR4350 (Mulwex-Thales AR2209) consistently produce accurate loads at safe working pressures in the 270 family of cartridges.

How do I sight-in the 270 Winchester for optimum downrange ballistics?

Here is how you do using Shoot! ballistics software:

Select a 270 factory load (or enter your favorite handload).

In our example, let’s select a Winchester 130gr Silvertip.

Now let’s optimize this load for you firearm…..

That 130gr Winchester load is best sighted-in 2.49 inches high at 100 yards for a 240 yard zero. Point blank range is at 284 yards – this means you can use your 270 and this load to shoot a deer holding dead-on (never high or low) all the way out to 284 yards.

Why The 270 Winchester Is Still Popular As Ever

The 270 Winchester is still popular among hunters who shoot at game the size of deer and elk out to 350 yards. The 270 Winchester, although producing ballistics a less impressive than the 270 WSM and 270 Weatherby Magnum, is still preferred by many hunters.

Why?

Firstly, its recoil is much less compared to the other 270′s.

Secondly, the 270 Winchester is an inherently accurate cartridge and most standard off the shelf 270 firearms from various manufacturers shoot MOA groups or less without major modifications like bedding, floating barrel, chamber work, etc.

Thirdly, its only about 200fps behind the 270 WSM shooting a 130gr bullet – but you won’t notice this difference under field conditions unless you’re consistently shooting out to 500 yards (average distance shooting at whitetail deer is under 200 yards).

The 270 Winchester, although producing less impressive ballistics, in reality has all the downrange ballistics performance hunters require to make the shot 99% of the time.

270 Ballistics And Shoot! Ballistics Software

There are 100′s of factory ammunition and bullets for handloaders in 0.277″ (270 cal) to search from in the Shoot! ammo/bullet database. Shoot! makes it easy to understand 270 ballistics.

Why Understanding 22 Ballistics is Important

The 22 LR is ideal for teaching novice or beginner firearm owners the basics of exterior ballistics and how to consistently hit targets beyond their usual shooting distance.

Ammunition is inexpensive so you can practice all day at the gun range. However, before you start buying 22 ammo based only on velocity believing highest velocity is the key to better long range ballistics performance from the 22, read the following.

Let’s compare the ballistics of 3 typical 22 Rimfire rounds

The trajectory graph below (take from Shoot! ballistics software) shows 3 typical rimfire rounds at different velocities (standard, hyper velocity and subsonic).

All rimfire rounds were sighted in to zero at 50 yards using Shoot! ballistics software:

Green line is the subsonic round (40gr round nose solid lead bullet at 1050fps)
Red line is the hyper velocity round (32gr bullet hollow point lead bullet at 1640fps)
Blue line is the standard velocity round (40gr round nose lead bullet at 1240fps)

At 50 yards the ballistics of each rimfire round are:

22 Ballistics And Velocity Loss

Look at the Velocity(Fps) column.

Notice how much velocity the hyper velocity 22 round has lost at 50 yards compared to the standard and subsonic rounds – over 340fps! The other rimfire rounds lost far less velocity. The Standard round lost only 134fps while the subsonic 85fps.

22 Ballistics and Wind Drift/Deflection

Look at the column named ‘Deflection(Inches)’.

This shows the bullet drift at 50 yards with a 5mph crosswind coming from the East (3 o’clock).

The hyper velocity round is affected the most (1.09 inches drift off the bullseye at 50 yards) while the subsonic round is least deflected by crosswinds at this range (only 0.62 inches).  The standard rimfire round is between the two velocity extremes.

22 Ballistics – Lessons Learned

The lesson here for shooters wanting to understand 22 ballistics is that high velocity usually does not equal better downrange ballistics performance.

The hyper velocity round shoots flatter out to 100 yards, beating the other 2 rounds, but at a price (accuracy usually suffers – read below to learn more). But when it comes to velocity (therefore higher energy) and wind deflection the ballistics of the other rimfire rounds are ideal. They perform just right across the ranges you typically shoot a rimfire.

Personal Experience with 22 LR Hyper velocity rounds

Over the years I’ve shot many different 22 LR hyper velocity rounds in a range of rimfire firearms. I’ve never found them to be as accurate as standard velocity rimfire rounds (as I define above in the 1250fps velocity range).

Accuracy is a big factor when shooting a 22 rimfire, especially when hunting small game. I want that small round nosed or hollow point lead bullet to hit precisely where I’m aiming for a clean, humane kill. So for me pinpoint accuracy is more important in a 22 rimfire than velocity.

This is why I choose to shoot standard velocity rounds firing a 38 or 40gr bullet. The heavier 22 bullets also deliver increased downrange energy so vital for a clean kill on small game.

What about Subsonic Rimfire Rounds?

A subsonic 22 LR round has its application in close range shooting (50 yards maximum) where noise could be a problem (i.e. buil-up areas or semi-rural locations). Subsonic bullets from a rimfire are ideal for close quarter pest control situations.

Maximum Range Of A 22 Long Rifle?

The downrange energy and trajectory of a typical standard rimfire round make it suitable to consistently hit small sized targets, under ideal conditions, to about 140 yards. Beyond this range the little 22LR starts to run out of steam and bullet drop and energy taper off rapidly. 22 Ballistics Conclusion

The little 22 LR firing lead bullets of between 35-40grs in weight and around 1250-1350fps appears to be the ideal in terms of accuracy, power and flat trajectory.

Our 22 ballistics demonstration above using Shoot! ballistics software and actual firing at the gun range or while
hunting support this claim.

Use Shoot! ballistics software to search our ammo database of over 100 rimfire loads to do 22 ballistics.

Ballistic Terms Explained:

Altitude: The height above sea-level of any point on the earth’s surface. As the altitude increases, there’s less drag on the bullet. SHOOT! lets you set the altitude to any value between 0 and 25000 feet above sea level.

Temperature: A change in temperature in the atmosphere affects the drag on the bullet. SHOOT! lets you set the temperature to any value between 0 and 150 degrees Fahrenheit.
Humidity: A change in humidity in the atmosphere affects the drag on the bullet, but not as great as temperature changes. If you are unsure what the relative humidity in your hunting area or local gun range is, set this to 0 (zero).

Barometric Pressure: A change in barometric pressure affects the drag on the bullet. A value higher than 29.92 In Hg will result in increased air pressure and thus increased drag on the bullet.

Wind Speed

The speed of the wind in Mph.

Here are some approximate wind speed figures when trying to determine wind speed while hunting or at the range.

2-4Mph — The grass and leaves move. Small limbs on trees also move.

5-9Mph — The grass starts to lean pretty well. Smaller limbs on the trees are moving constantly and thicker limbs barely move.

10-14Mph — The thicker limbs are moving and the grass is being pushed strongly during the stronger gusts.

15-20Mph — The trees are swaying and the grass is in constant motion.

Wind Direction: The direction of the wind, relative to the shooters position.

For example, a wind that is blowing towards you (in your face) while shooting is a headwind (coming from 12 o’clock or North). A wind blowing from the right side of your shooting position is a crosswind coming from 3 o’clock or East. SHOOT! allows you to enter a custom wind direction angle, like 34 degrees or 220 degrees (anywhere between 0-359 degrees).

Ballistics Terms Explained:

Velocity: The speed of a bullet, measured in Feet per second (fps).

Energy: The amount of energy a bullet develops, represented in Foot-Pound (Ft-Lbs).

Path: The bullet path is the vertical distance of the bullet’s trajectory above or below the line of sight.

What is the Line Of Sight? Imagine a straight line being drawn from the sights to an object or animal you are aiming at. This is defined as the Line of Sight.

Drop: As soon as the bullet leaves the rifle’s barrel, it is subject to gravity and begins to drop immediately. If numbers in this column do not vary markedly from range to range, then the load is a flat shooter. Drop is always measured from the Line of Departure (LOD). That is, the path of the bullet as it leaves the rifle’s barrel.

Drift: A lateral change in bullet trajectory caused by crosswinds or angled winds (i.e. coming from North West, South East, etc). In other words the bullet is being pushed to one side of the Line of Sight (LOS).

TOF: The time it takes, in seconds, for the bullet to reach a given distance.

The experiments possible with Compare Loads are endless.

For example, you could compare three similar 130gn .270 Winchester bullets from different manufacturers, fire them at the same velocity and observe which bullet drops less and therefore shoots flatter over the longer ranges. If you increased the velocity by 100 fps, what difference would this make? You can easily explore these scenarios and many more with Shoot! using ‘Compare Loads’.

You can also graph the ballistic comparisons out to 100, 250, 500, 750 or 1500 yards/metres.

Watch the video to learn how quick and easy you can optimize all your loads/guns in just a few steps…

Ballistic Terms Explained:

Target Range: The distance, in yards or meters, to the sight-in target. For example, you setup a target at your gun range 100 yards away. This is the distance to the target.

Zero Range: Zero range is defined as the range where the bullet drops back through the line of sight (LOS). If your Rifle/Load combination is zeroed at 200 yards, then this means the bullet will strike the centre of the target at 200 yards.

Sight Settings:

Tells you how high or low to set the sights (inches) at the target range, in order to zero the bullet at the given zero range.

For example:

Set sights to shoot 1.2 inches high at 100 Yards for a 220 Yard Zero.

This means you need to sight-in your gun to have the bullet impacting +1.2 inches high from the bullseye of the target at 100 yards. If you then had the same target at 220 yards, took aim at the bullseye and fired, your shot would come very close to hitting this mark (depending on how good a shot you are).

Point Blank Range:

Point Blank Range is 265 Yards.

Point Blank Range is an extremely important concept for hunters to understand. It simply means the distance at which you can hit a target without having to hold over or aim under. This depends on the vital zone of the game animal.

For example, an average sized deer has a vital zone of 6 inches. SHOOT! calculated a point blank range of 265 yards for your deer Gun/Load. What does this mean? You can be assured of a hit within the vital zone of a deer without having to compensate for holdover all the way out to 265 yards.

Firing Angle: Do you hunt or shoot in hilly or mountainous country where shots are taken downhill or uphill? You can enter any firing angle up to a maximum of 90 degrees. Remember that any angled shot, whether up hill or down hill, shoots high, so you have to hold low to compensate.

Ballistic Coefficient: Simply defined, it represents how well a bullet resists air drag. The higher the number, the better the bullet retains velocity, energy and thereby shoots flatter.

The 5.56 is another way of saying 223 Remington – they are both the same cartridge and produce identical ballistics.

The 5.56 is popular with varmint and target shooters. Its vital to understand 5.56 ballistics in order to score hits at long range on small game or competition targets at 700 yards plus.

The Shoot! ballistics program includes close to 100 factory ammunition and bullet data on the 5.56 or 223 Remington. This makes the job of comparing 5.56 ballistics with any other 5.56 ammo or bullet very easy.

So if you ever wanted to calculate and compare 5.56 ballistics just use Shoot! ballistics software – you won’t regret it!

The 300 Ultra Mag from Remington is relatively new to the shooting world, offering incredible downrange ballistics.

The 300 Ultra Mag fires a 180gr bullet at a sizzling 3250fps. Because the 300 Ultra Mag is designed for extreme long range shooting, its essential to work out optimum sight settings and point blank range using Shoot! ballistics software.

To realize how flat shooting the 300 Ultra Mag is, use Shoot! ballistics software to compare 300 Ultra Mag Ballistics to other 30 caliber favourites, like the 30-06.

450 Marlin ballistics is similar to the famous 45-70. The case is virtually identical in terms of powder capacity – so ballistics performance is just about the same.

As expected, the 450 Marlin generates tremendous ft.lb of energy. Firing a 350gr bullet at over 2000fps, the ballistics is quite impressive at 200 yards with only a 5″ drop in trajectory.

From the ballistics figures above, the 450 Marlin is more than sufficient for taking all North American game.

Its crucial to work out 450 Marlin ballistics before heading to the range, because using the wrong sight settings (ie, 1″ high at 50 yards) could result in a less than ideal maximum point blank range.

You want to squeeze every ounce of ballistic advantage from this cartridge and Shoot! will show you how.
