I broke in the the barrel on my 300 SAUM this weekend and I believe it has the potential to get me out to 700 - 800 yards. I loaded up an old box of 165 gr Game Kings with Varget and IMR-4350. They shot around an inch at 100 under less than ideal circumstances during break-in. Speeds were 2850 - 3050 depending on load with no signs of pressure. Here are the details and here is what I am looking for. Remington Model 700, 24" 1-10". Muzzlebrake, lapped, bedded, trued etc. Looking for bullet suggestions for elk out to 700 yards and powder suggestions to push it. Let me know if more information is needed. Thanks for the help.
