Re: Rookie looking for great help
A light weight bullet won't get you to 1000 in the 308, goes subsonic too soon. The 175 Sierra MatckKing is my choice for my rigs. I shoot 1 bullet all the time, load it to how the rifle likes it, and go. The charts are the same so it makes range work so much easier. I have 3 rifles in 308- three different twists, a savage 1-10, a custom remington 1-11.25, and a Rem LTR 1-12. All shoot the 175 SMK very well, and their fav loads are within 200 fps of each other. I have the savage primarily for shooting subsonic ammo for my quiet shooting, 1-10 will stabilize the heavy bullets required.
Your wants seem to require more power than the 308, sounds like you might upgrade to a 300wm in the future. 1-10 is a good twist for that round. Anything larger starts to get expensive and punishing without a brake. A deer pops out at 750 and I'll grab my 308, deer pops out at 1000 I'll take my 338 lapua out of the truck. That is my escalation of force since I sold my 300wm Sendero. 308-.37 cents per round, 338LM- 2.10 per round.
