I have a 22 with a match bbl. Its the same way. I went thru hundreds of dollars worth of ammo to find the one it wanted. Eley Match Plus Extra. Nothing else I found will do. It will shoot it though...
Went thru all that, had it pillar bedded, trigger job and a bunch of other work. One match and my buddies that were beating me, wont shoot with me anymore.
Guess that makes me, THE WINNER!!
