Hello, This is my first post, so bear with me. I have a hair brained idea for a long range rifle. Ruger 1, 28" hart barrel, 375 HH AI, muzzle break, 20 moa base, Millet scope. I own a #1 in 375HH so I have lots of brass, thats the reason for the caliber. Any thoughts? A friend is shopping for a 338 lapua and has rekindled my desire for such a weapon, but I'm incapable of doing anything the easy way. Any advise would be greatly appreciated. Mac
