My custom 7 ultra with the 180 VLDH, 50 BMG, Fed 215's shoot at 3300fps. 29 inch Benchmark barrel. Would try RL 33 but it's shoots so great with the 50 BMG
I just dropped my rifle off to gunsmith. Getting magazine lengthened and freebore taken out. Trying to get to lands. Hoping to improve my accuracy a tad. How much speed can i expect to lose going from a freebore to touching lands?
