I went from sizing 225 to 226 and groups shrunk. I then started powder coating and gained a bit as well. This from AR's and a bolt rifle.
Thank you ! Just what I was hoping

Throat dimensions might be the key to this. I had a 9x56 MS with .353" groove diameter and a long throat that began at .359". Bullets sized .354" wouldn't shoot worth a pinch of the proverbial, but .360" were tack drivers.
It'll be handy if I never need it.

As Wilderness said, throat dimensions are the key. Also, the as cast dimensions of bullets from your mold. As a rule, I use the largest diameter bullet I can that will chamber easily, not just .22 caliber, but in all calibers. Quite a few are used as cast, without sizing. I make my own sizing dies, about .0005 larger than the bullet, and just use them to apply lube. I also make my neck expanding dies, so that I don't squeeze the larger bullets smaller when seating. So far, all my rifles shoot their best groups with as large as will chamber easily bullets.
My go to "sizing" is .226 - .227 for most of my factory/military chambered .22 cals. The exception being one tighter match chambered rifle. Most of my .225 moulds drop bullets cast of #2 alloy at .227 - .228. I seat and crimp on the GC in a .225 H&I die in a Lyman 450 using the GC seater. That does not size the drive bands. I then lube those in a .228 H&I die which does not size them. Those give the best accuracy in my 22 Hornets, my 223/5.56s and 22-250. In the one match 223 with a tight minimum spec match chamber, I then size the GC'd and lubed bullets in a .225 Lee push through sizer.

In rifle chambers the bullet should be a tight slip fit into, but not larger than, the throat of the chamber.

I use a .226 sizer for 223/556 and 22H
But my new CZ-527 (222rem) prefers .225
When I bought the custom 226 sizer, I also bought a .227, but that one has never got used.
