I had a barrel custom reamed by a gunsmith to the dummy bullet I made. Easy, quick, doesn't cost much. If you're buying a new barrel, ask to have it chambered to your dummy bullet. Usually no extra charge.

I use a .090" for 75gr and get over 3000

.095 in my 223 and 223AI. Let’s me load them out a bit. I’m a jump .020 kind of guy, never loaded touching or jammed.
Don’t want a cease fire, unload command leaving a bullet stuck in the rifling and powder spilled in your action, real PITA.
