I build custom rifles
and ile take the 300 wm any day i shoot a rem 700 action 26 inch shilan varmint barrel fluted for wheight reduction and a muzzle brake
1-10 twist. Im loading 200 grain accubond with 78 grains h1000 at 30 thou off the lands at 3060fps through the chronograph. hand loads have all been within 15 fps and most within 10 fps of eachother and .50 groups at 100 yards.ive shot black bear, elk, and deer with this rifle from 60-715 yards. Acording to nosler they recomend maintaining 2000 foot pounds for elk witch in my rifle takes me out to 800 yards. For deer i would go down to 1800 fpe witch is just past 900 yards. I love these 300 wm and it has never let me down. Nosler has now produced a 210 grain accubon long range bullet with an even higher BC then the standard accubonds i havent been able to get any yet i talked to nosler and they told me they are batching them in april 2014 and you can bet i will be ordering some these should be the best thing since bread and butter lol if they shoot well they will cary well past 1000 yards. Plus the benefit to the 300 wm is you dont use as much powder as the bigger canons and you get just as good of results and we all no powder is like gold right now. Well good luck with youre rifle and if you got any questions feel free to ask.
