Just got back from the range. FINALLY caught a day with virtually no wind. Got there at 8am after looking at the weather and seeing it dead out there. Had some 5mph gusts here and there but Ill call that dead compared to the last month of windy days! This Keystone Accuracy RimX Green Mountain is straight hammering at both 50yd and 100yds. Some tiny ass groups laid down and awesome 10x5 and 6x5 numbers. Best deal on RimX barrels going right now for the money.

20" Keystone Accuracy Green Mountain
22LR Match Eachus chamber (my custom chamber)
100yds
0-5mph infrequent breeze
56F
This chamber continues to shot it shoots almost everything I throw at it good. I have not lot tested or cherry picked this as magical ammo. I grabbed and shot 2 lots of new bricks of CenterX I just received and shot at 50yds, and same lot of Ultramatch Ive been shooting. Shot them all great. That best group of 0.187" is just awesome. This Keystone Accuracy GM has shot my personal best in group size at both 50 and 100yd, best 6x5's, and 10x5's.
I have ever shot fired on the below target on video from this morning. Just gotta pull it off my 4K camcorder and post it up.
Best 10x5: 0.662"
Best 6x5: 0.592"
Best Group: 0.187"
I think I'm correct, but wanted to confirm the numbers posted are from 100 yards. You mentioned shooting 50 yards also so I wasn't sure.
