Good post!! Every time I read about the mysterious POI shift that gets talked about so much, I always wonder if it is simply just the wind? Sure doesn't take much wind to move pellets around.
Good write up AZ! I have a question about elevation and velocity though. I have a highly modified crosman 1322 with a discovery barrel and FT piston and valve. I happen to know somebody on the east coast with the same gun and setup as mine. He uses less pumps and achieves higher velocities than me, why is this?
