Got a chance to shoot all the QB/HPA conversions during a test of a pump.
Only 20yards, but a pair of 5-shot groups with each pellet. Have come to expect groups near .2 @ 20yards, and each gun managed to supply at least one pellet that could average that for two 5-shot groups (which isn’t much of a test, but these rifles are already well known/well tested).
