.300 Win. Mag. & 240gr Woodleigh

[Slamfire]

Using the Woodleigh manual load data for reference I developed a load with the 240gr PP SN for my Grey Wolf. A charge of Re22 produces a muzzle speed of 2700 fps (chrony positioned 7.5m from muzzle). Should be a pretty decent penetrator with controlled expansion.

Woodleigh recommends for this bullet a minimum twist rate of 1:10" for proper stability. The 300 Win Mag Grey Wolf has a 24.6" 1:11" twist barrel. Turns out that accuracy is acceptable with a 1:11" twist. The Berger Bullets twist rate calculator predicts comfy stability for a 1:11" twist at 2700 fps muzzle speed.

Neat. Not many guys load that heavy in a 300 mag. Most would jump up to a 338 or even a 375 cal.

Try some at 200 yards to see if they are tipping.

 

[Slamfire]

No indication of bullets cornholing on target at 200 meters.

You could probably print your own targets for less than you spend on masking tape.

 

[Slamfire]

Masking tape cheep. 1" wide x 60 yd long roll is about $2. Just need ~1/3" long piece to cover a bullet hole. So a roll will cover [60 yd x 3 ft/yd x 12 in/ft x 1 shot / .3" =] 7200 shots for $2. Goes a long ways. Quite thrifty. Especially when it's a salvaged target recovered with only a few holes through it. Must be my Scots ancestry.

Earlier results with the 240gr and Re19 at lower muzzle speed. And accuracy with the 180gr TTSX using Re19. With the 240gr bullet I think the 300 WM could well be a viable hunting rifle.

Masking tape good, okay?

Masking tape is good! penny saved is penny for powder/ primers/brass/bullets/gas/cigars. Ok?
This is 5 rds 6.5 Creedmoor while doing load testing. Got the info I needed and that's all that mattered to me. Was a broke student for many, many years, old habits die hard

I shoot the 240gr PP in my Ruger No1 300wm, with H1000. About 2650 fps as well from 26" pipe. Not a hot load

It seems the OP owns a variety of calibers and likes to push velocities, charges and purpose.

I could see myself developing a similar load if I was Moose hunting in the North Peace. Especially if one could find a heavy short range, stopper load that had useable/common POI with your general purpose load.

For me the 300wm is one of the most versatile calibers. Light projectile for deer, about a 200 gr controlled expansion for Moose or Elk, 208 for target, now a 240 as a stopper. Useful for a handloader with only one rifle.

For any purpose if I needed a 240gr projectile I would probably choose a 338 or 375. The Mark V i bought from Ted in 340 pushing 250 partitions sounds about right.

No changes to windage or elevation settings. Rifle was sighted in as shown for the 180gr TTSX, 3" high at 100 meters. So the 240gr load is useable with how the scope is set for the 180gr TTSX load.

Woodleigh lists 2590 fps maximum muzzle speed for the 240gr using H1000. Quite a range of bullet weights and types for the 300 WM.

What's the OAL with this 240 gr bullet?

 

[Slamfire]

OAL = 90mm for the rounds to fit in the Sako 85 magazine.

A 200gr partition at 3k will do everything you'd want a 30 cal to do. It's my one load for everything in my 300 mags.

There is nothing a 240gr woodleigh will do that a host of other readily available bullets won't do. The 180gr ttsx the op has being one example.

I have some 190gr 7mm bullets that are "neat" but I wouldn't use them over a bunch of other bullets.

 

[Slamfire]

Looking for straight-through penetration from my 300 WM. The 240gr Woodleigh should excel at that. High weight retention with controlled expansion.
