This isn’t so much an “I want this, how do I make it happen?” as it’s just one of those random things that pops into my head when I’m in that half awake, half dozing state before the alarm goes off.
I’m pretty sure the .450 Bushmaster is the closest answer even though it’s above .44 Mag power level as best I recall and .458 SOCOM even more so.
Is there another factory option with off the shelf ammo I’m not thinking of?
Thanks!
