When the frame on my old HS Victor started cracking in the third location a couple of years ago, I bought a new 41. I mounted an Ultradot sight and Fung grips, and made it my bullseye gun.
I have generally been happy with it, but it has one quirk that is driving me crazy. More often than not, the first round of slow fire goes in the five-ring at 1:00, and the hole is noticeably elongated, indicating that the bullet is tipping. This is with CCI SV ammo, and occurs even though I break the shot in the black. It only occurs with the first shot. After that, everything is normal. For a while, I tried to convince myself that I was causing it by flinching, but I don't think even I can flinch enough to cause keyholing, and I almost certainly flinch more than once.
I haven't yet designed an experiment to see if cleaning, lubrication, disassembly and reassembly, or the way I hold my mouth has any effect on this problem. I thought I first would ask around if anyone else had one that does this.
