Recently I swapped from a 20 to a 22 barrel. My zero ended up 10 low at 100 yards. I know all barrels are different but I wouldnt think it would have been so low. I pulled the scope and mount when I did the swap. I zeroed it again day of break in but I went ahead and pulled it and re-torqued the mount and scope anyway when I got home. Any thoughts on this? I have not shot since but will this coming week. Is it barrel harmonics being different? I could see it being high but not so low. I have 22 moa of adjustment left in the scope (Vortex Diamondback Tactical 4-12 and Aero Precision Mount). Barrel is a JP 22 and I bedded it for the first time Ive ever tried it. Shoots tight groups.
