I have two 22BR barrels for my Tikka done with the standard .050 reamer. They are 1-7 Bartliens and I shot the 88gr ELDM at 3000-3150 with Varget, H4895, Rl16, and 4166. I sold my standard reamer and if I order an new one it will have a .274-.275 neck and a .100-.130 freebore. There is a good discussion on another forum about reamer specs for heavier bullets. I shot a few 90gr A-Tips and they were pretty amazing. They are being used a lot in the 22 GT for PRS.
I shot one season of local PRS matches with the first barrel, it has 1800 rounds on it and still at .25 moa. When doing load development, I shot two three shot groups at 412 yards that were .38" and .257".
I ran about 20 of the 53gr V-Max through my first barrel over 32gr of Varget and had them going 3600 fps out of the 26" barrel suppressed. They hit the 400 yard plate pretty hard. I have considered cutting my first barrel back to 18-20" from the breech end and having it re-chambered with a different reamer for a handier coyote calling rifle.
