I have the 450 and it kicks a$$. Also very, very accurate (1 hole at 100) Parts are parts with one exception, the trigger, get a goog one. I use JP. Also a slip on limb saver recoil pad will make it feel like a .223.
well i did some more research and soul searching and i think I will stick with the 450 for this build. ballistics performance consistently edge .458 out (just barely) and the ammo is cheaper, which i find weird because the only companies making the loads are hornady and remington and the .458 is made by more companies but still more expensive. the only mod that the 10 rd magazine will need to properly feed the 450 is a single stack follower. the 458 is an awesome round but with the research i did and my own preferences i think it'll be the 450 bm for me.
The socom quickly outstrips the 450 in hitting power when you go to larger bullets.

@ Canebrake if I read your thread right . My remington R15 450 lower wont be compatable with a 223 upper cause of the buffer spring? Is this right. The 450 is a great bear gun and was thinking of getting a new upper in 223 for a cheaper plinker. Or am I just wasting my money?
