twist needed for .308" 240g SMK's??
hey, i am now the prowd new owner of a custom 300 ultra mag, was looking for a gun to build a 338 edge but this kinda just jumped out at me, it is a remington 700 action, h-s precision stock w/ adjustable cheekpad and LOP. and a 30" stainless barrel with a muzzle brake.
i'm wonderin what twist is needed for these heavy bullets, i'm in the process of tryin to figure out the twist in the barrel but my dewey rod is bein a pain.
i would like to try sierras 240 if at all possible, but may settle for any in the 200-220 range
also wonderin what kinda loads should i try in it?? its my first experience with a big 300, other than a 300 win that wouldn't shoot baseballs at 100 yds.
also shoppin for a scope and rings/base as i speak!!! any advice is appreciated, i'm a novice at long range,,,, 500 is about as far as i've shot.. but really wanna shoot at 1000+ what do i need to get started??
