James, your load sure looked good on the 800 yard EGG Challenge

 

Thanks Randy, later this week I'm taking it to 1K and test hopefully for the upcoming 1k nationals.

 

James, don't forget the 1428 yd egg lies in wait

My hunting load for the 300WSM is :

175 gr Barnes LRX
65 grs RL-17
CCI 250
Nosler case

The load is very accurate and will shoot sub 1/4 minute at 300 yds. My rifle is a commercial Mauser action with a #4 fluted Pac-Nor barrel, Jard trigger, B&C "massaged" stock, Weaver Euro Super Slam scope with lighted reticle in QD Warne mounts.

 

HI,
Not sure if this is the right forum for this question,if not I'm sorry, I am thinking of getting a light weight 300 wsm for all around hunting,mountains,woods ect,is a 22"barrel to short for that caliber,if I want to say shoot long distance,or will it work for being all around good gun.
Thanx

 

I'm looking for a good load for shooting steel , 155 grain only , best bc I can find is Sierra 155 TMK . 519 . I have a 24 " 10 twist . I want something that I can see my hits in the scope , this gun jumps on the bipod sorry it's a 30 wsm , will a different bipod make any difference have a Harris BR on it , do I need a wider standing one? My friend loves his
sInclair tactical one
Thanks Mark

CCI BR Primer (Lg-Rifle) - 63.5 gr. H-4350 using a Berger 200.20X hybrid .012 off the lands. MV was 2930 fps. (This is all the further I want to go up, & 61.0 grains shot good & was approx. 2810 fps)- Both loads produced .4 to .5" groups (5 shots) at 100 yds. Temp was in the mid 90's on a humid day in So. Central, La.

 

Any idea when the 300 WSM Guide will be available?

 

I'm wanting to get some dope for the same thing...I've been shooting the 155 Sierra Palma in a Savage Model 26 300wsm 24" barrel out to 600yds.

 

300 wsm Stiller TAC action, rock creek 28 inch barrel 1 in 10 twist. Jewel trigger and 32 power nxs Nightforce. Shooting suppressed.

215 target vdl Bergers loaded with 57.5 grains of h4350 with federal 215 primed Norma brass loaded at 17 thou. This is my 1000 yrd load and will usually hold half moa groups

210 target Berger loaded with 60.0 grains of h4350. Norma case fed. 215 primer loaded at 15 thou. Shoots good as well

220 Sierra matchkings loaded with 57.0 grains of h4350 in a fed 215 primed Norma case loaded at 12 thou. is my plunker load. These shoot decent and I have a bunch of them I bought from sal on the classifieds
I’m using h4350 because of the throat of my rifle. Any matchkings or non vdl bullet I load compresses h4831 quickly

 

Velocities?

I'm looking hard at 300 WSM for 1 mile. Looks like it may just cut the mustard at 1760 with a 215 hybrid humming at 2900...just wondering if that's a realistic expectation for this caliber/bullet combo.

 

Thanks Mach. I think for the extra few hundred yards the WSM would afford me over the 6.5, that "diminishing returns" would be received if I went that route.

In other words, why stop at a mile when one can go further!

 

FYI snipers hide has a group buy going on right now for a 50 bmg McMillan action for a decent price. Only draw back is that it’s a shell holder bolt design but it would still be a nice start to an elr build
