 and you don't have to change a thing in your gun. If you want to just get a box of ammo and try it in it, you could do that. Just go to Double Tap Ammo, and you can buy a box. They'll send it to you. I would say, I mean, there's nothing wrong with a 460, but you've got to, as you say, you're going to have to change some things up, get a new barrel. You might try the 450 SMC from Double Tap Ammo. Just shoot some of that ammo and see what you think. 450 FMC, I haven't looked into that at all.
