I have thought about my build dilemma. I have been.studying on doin a .408 or .416. But the more I think about ammo components and the overall build price, I believe im.gonna take my 700p .338 lapua and build it. I already have.the optics so thats a start. I wanna do a trigger, barrel, and stock or chassis system. Im thinkin the jewell trigger. A manners or mcmillan stock that is adjustable. or an AI chassis system. But im not sure on what barrel and what other mods to do at this time. I would like to do a heavy barrel for sure that is fluted and alse has a brake and.threaded for a can. I already have a tac-ops bolt knob but I would like to flute the bolt if possible. I think this will serve me well as the .338 will pull any distance I.can.shoot around here. I may also steup up to the 300gr bullets. My 250 and 285 grain bullets shoot.great. Any opinions on modifications?
