Short Barrreled 300wm

[fmuguira]

As a reference point to 30-06.... Hodgdon on line data has 4 180 grain loads exceeding 2800 fps and 9 more that are between 2700-2790.

That said I still own a 300 WM with a 24" tube.... about the minimum length in my opinion for that case to realize it's full potential.

300 WSM 21" barrel with H4350 pushing Hammer 181 grain Hunter at 2,950 fps

Wow, that's impressive and I have 8 pounds of H4350.

Anyone running a short barreled 300wm-22" or so? Just wondering how well something like that does, how much velocity is lost etc.?
Would probably add a brake, wanting a lighter weight backpackable rig that would give me a little more than the .06.

I developed a load a few years ago for a 300WM 18" Barrel on a Desert tech SRS Covert. I tried numerous powders and I got the best results with H4350. I used Norma Brass, 185 grain Berger VLD Hunting Bullets with 69.8 Grains of H4350. 40 thou off the lands. Velocities of 2720.
Hope this helps.

Guess I'll be switching powders!

I have a Savage 116 Bear Hunter in 300 WM that has a 23" barrel, that's including the factory muzzle brake. I want to say that the barrel without the brake would come in at about 21". It's a shooter, with 200 gr Nosler AB's I am seeing right around 2875 FPS with my handload. This gun is still offered by Savage, but they now call it the 110 Bear Hunter ...hope this helps.

I bought the 16 Bear Hunter is 300 WSM to build a Sherman off of but was curious of the WSM's legendary accuracy so I started by chopping off the Savage brake with funky 9/16-28 threads(I think) and rethreading to 5/8-24 and added a Beast. Ran 100 rounds for break in and FF brass with 200 grain pills and IMR 4350 using berger starting loads (~59 grains at ~2700) at mag length, straight from the Chargemaster. I let a non shooter GF burn up some rounds and she went something like 12/15 on steel 600 to 800 yards. Then I annealed, sorted, etc. and ran a ladder in 0.5 grain (FX-120)increments with H4350 at 700 yards and came up with a 1.5 grain (2 shots of each 3 charge weights, 6 shots total)window that printed 2" of vertical and ~30 ES. I have not retested yet but I narrowed it to the lower section 1.2 grains of the window and have 8 rounds of each charge to shoot in 0.4 increments. Scope is a Zeiss V6 3-18x50.
I kind of like this $600 rifle and am not sure I want to tear it down, but that 300WSM is pretty easy to load for. Probably end up doing a custom in 300 WSM...LOL

I have an out of the box Browning 300WSM and added a brake. I shoot Barnes 168 g. TTSXs at around 31-3200fps with RL17. I've never shot anything over 550 yds, but it's been lights out for lots of great animals, including 3 of my 4 sheep and a top 20 caribou. I like the 22" barrel because of the hunting packability and I've never noticed any need for more length. It's been a great hunting rig!

The US Army runs 22" barrels on the XM2010. No issues.

Again, Thank you all for the replies!
I am thinking about this for a TC Encore rifle which tend to be on the light side anyway and would be really handy in a 22" barrel. I've had good accuracy with other barrels on this setup! Kinda wish it wasn't such a pain to get a suppressor!!

I have a 300 win mag with a 22" barrel and am getting an average of 3025 fps with h4350 and 180 gr hornady interbonds with good accuracy. The rifle is a custom with a 12 twist barrel I got a good deal on at a pawnshop.

I have savage 110 tactical 300WM with 20" barrel getting 3050 180gr ballistic tip with RL 22, 75.5 gr. This load has worked wonders in 4 different rifles, sub 1/2 moa. Velocity with magneto speed

Have Sako SV with factory 18"300 wm....Open sighted, got for Africa/Alaska hunt that got cancelled. Been in back of safe for yrs now. So put 2.2-9 Sworovski on there and man does that combo shoot 180-190's on top of H4350 with vel in the low 2800's Very mild recoil too. cant wait to drop an Axis this yr for some meat with that rig...
