Re: Load for 300 Winchester Short Magnun
I've had a Savage Mod 16 in .300WSM for a little over a year now. I think you'll be pleased with it.
The load I took hunting this fall is 67.0gr of RL22 under a Combined Technologies 180gr Ballistic tip, lit by CCI large rifle magnum primers. I started with Winchester brass and was shooting about .75" at 100yd. Changed to Norma brass and it went down to .50". One round through the shoulders at 275yd was an instant stopper on a big pronghorn doe.
If you have the plastic stock, be sure to hog the foreend out pretty good if you freefloat it, because a hard squeeze of your front hand or the weight of the gun on a bipod can bend the plastic enough to touch the barrel. A skim bed around the pillar contact points and recoil lug seems to help too.
There is no "overkill". There is only "open fire" and "I need to reload."
