First off I'm a new member an have been shooting an had about every kind of firearm but I'm by no means all knowing an would like some usable feedback. Im currently building a REM 700 SA, Benchmark 24" 8.5 twist w break barrel, AX chassis, jewel trigger, etc. Wanting to know what is a great BC an speedy bullet powder combo that is good for this? I know most are runnin 140 berger, sierra, nosler is this too much to push on a 8.5 twist? Would a 130 be better? Will be shooting 1000 ish and up if possible, ur thoughts...
