It's a .25 using the 25.39's
The targets are 1".
I didn't notice until later that the pellets I used were my culls from initial sorting. None of the culls were real bad, but many had dings on the heads and stuff like that.
I have not messed with the settings on the rifle at all, and won't til iI use up 5 tins of sorted 25.39 pellets. When those are gone I'll be moving to the mk2s and will adjust for those.
I wanted to do 5 shot groups but as I had little time, and only 1 mag, I'm afraid I wasn't very consistent in the shot numbers, plus a couple of the targets got blasted off because I didn't spray them after sticking them on.
