both barrels same goove specs?good shooting btw
Thanks Ron,YES, some holes in the target seems to be not totally symmetrical.l have to taste them again whit the cardboard and also at different velocities . JSB heavy I was shooting from the same barrel in to the thick cardboard and I may see any asymmetrical holes at the target.I seriously not understand at all why CF stiffening of barrel may act so huge inaccuracy .https://www.gatewaytoairguns.org/GTA/index.php?action=dlattach;topic=137985.0;attach=235215;image
