I'm seeing a lot of flyers, which is an indication that you need to work on your trigger skills. BTW, don't be insulted by my statement because I have had the same problems. Back in 2008 I got it into my head to see how accurate my tensioned barrel model 620 was and it took a 2 power scope and practicing twice a week for 6 weeks to get under an inch at 50 yards from a sandbag rest. Two things I learned from that experience. One was that releasing the trigger perfectly was NOT as easy as many think it is. The second was that consistent management of the recoil is critical.

Sum it all up and shooting a handgun with real precision is not nearly as easy many assume it is. It takes constant and regular practice with lots of ammunition expended. Actually more time and money that I am willing to expend so I am quite content with simply shooting "well".
