222, 223, 220, 22 BR, 22-250, 22 Creed

Perhaps the .223AI and the .22 Creed cover the need for reamers..

I have a couple of standard .223 reamers, a .22-47, .22-250 and the AI version, a Swift and a couple of .22-.243 reamers.
After trying them the first two mentioned work for me most often. Both feed well in factory set ups and both offer great performance on either end of the spectrum.. JMO.

One other thing to think about, if your main concern is PRS, the cartridge needs to feed reliably from a magazine. For varmints, that isn't as much of a concern.
As a side note, I've thought about a 22x47 Lapua....but then I think why not just do a 22-243 of some sort that I can get dies for.

Or a 22cr, where ready to load brass is available from one the best sources in the world, alpha munitions. Throw a 250 or 251 bushing into a 6 creed die and you're good to go.
