ESSCEE i went through all the issues ur seeing when i was planning my rifle. i went w 338 rum, and i can tellya that for it to function as a repeater w the factory magazine i need to keep my OAL to 3.590 or a bit less. i havent bothered tryin any 300g bullets, but w various 250s i cant use the slow bulky powders many prefer - the loads are awful compressed. fortunately my rifle likes H4831SSC, and gives me the velocities i wanted w my 28" barrel, without using compressed loads. my rifle shoots right with my buddys 338 lapua, and cost less than half as much to build

if stockade is doin a mag conversion im guessin hes gonna get mighty busy hehe...jc is stockade modifying the magazine? is the issue the feed lips?
