Alright guys, I know I posted earlier about either a .300 or .338 Ultra and settled on the .300 Ultra with all you guys advice. Now I am kinda rethinking everything and thinking that is to much gun for the distances I can shoot. I am only able to shoot accurately out to 600 yards. I am thinking a .300 Win Mag. with either 180g or 200g bullets should be able to get me out to 600 yards with good killing power for elk and bears. But I still want to know that they are being hit with a lot of energy and know they are going to go down within 100 yards, preferably no more than a couple steps. Also, Norma makes .300 Win brass. While only Remington makes the Ultra brass and I have heard that Rem brass is kinda shitty for LR. I have also read by a lot of other people that the big ultra mags have real bad tendancy to string that far because its hard to get a low deviation velocity over the chronograph. Large amounts of real slow burning powder I heard is not the best. Thats another reason I was thinking about sticking with the .300 Win. I have worked up loads for them and only had 15fps difference. I would rather hit the animal with somethign accurate and powerful instead of hitting it with something more powerful in a bad spot, it will do no good for me or the animal. How far do you think a .300 Win is capable of taking elk and bears and with what bullets and muzzle velocity? Also what is your guys theory on impact velocity for expansion, and impact for energy? I read for deer and elk you need 2,000fps and deer you need 1,000 lbs of strikign energy, and for elk and bears you need 1,500 lbs. What do you experienced LR hunters think of those numbers? Are they reasonable? Sorry for so many questions, but I dont want to be overgunned and develop a flinch when I can buy a good old .300 Win and be completely satisfied for my capability's. Thanks.
