So, I've been noticing this on MOST, but not all of my springers. For instance, my .22 cal HW 97K is an exception. What I'm seeing is that after I've fired a dozen or show shots from a piston powered gun, the groups begin to tighten up. Now, I understand that this could just be due to me getting warmed up, but here's my theory. I'll bet that it's not a new idea. This must've crossed many an airgunners' mind....
Could it be that the piston seal is heating up during the first few shots and that once its become more pliable, it forms a more consistent seal? It just seems to make sense to me that this would be the case. However, as I've already mentioned, my 97K is one of the few piston guns that I own which always seems to shoot point of aim no matter how long between shooting sessions, so.....
What are your thoughts...?
