Re: Medium Range Big Game Build
IMO, making an 800 yd elk out of a short action is stretching it a little. It can be done but it's pushing the edge a little. The WSM case is the one that would do best. I would pick the 300 over the 7 because we are talking elk. The 7 can do it but the 300 can do it better and the 300 WSM is very capable of shooting larger than 200 gr bullets very well. With RL17 I pushed 210 Bergers @ 2930 out of a 24 3/8ths barrel. Add 2" of barrel and shoot 215's which are a little faster than the 210's and you're looking @ 3000 fps with a .7 BC bullet.
That said, if you want to load as a repeater and seat close to the lands you'll need a short throat and your bullets will encroach on a lot of case space. I loaded mine out to the lands which prevented putting any more than one down. I was able to put one down with it's nose above the box and have a 2 shot configuration.
If I build a 300 WSM, or any WSM, it will be on a long action. I did just that with a 6.5 WSM on a standard Vanguard action.
You will never know how much it has cost my generation to preserve your freedom. I hope you make good use of it.
