[QUOTE="Jud96, post: 1891997, member: 69478"] Personally if I’m building a .338 I’m looking to shoot 250+ grain bullets in it. Heck a .338 RCM would get close to 3200 with a 160gr in a 26” barrel. If you want to shoot those weight bullets then build a big 7mm or .30 cal magnum. Getting 4000 ft lbs of energy at the muzzle can be done with a .300 Win Mag pushing 220s at 2850fps. If you want fast and flat for big game, shoot 180 Accubonds at 3200fps. You’ll have less drop and more energy down range than a 160gr .338 at 3300 has. I’m not a Ruger guy, so I can’t comment for sure, but I’d look into the magazine box length of an M77 to see how long of a cartridge you can fit in there. That will be a big determining factory on what cartridges to look into. [/QUOTE]
