I am doing a pellet test for my .177. I am looking for accuracy cutting cards on edge at 30 ft with smallest groups and less cost. I am using a death grip tripod to take out human error. Here are some early results. These are mostly 5 pellet groups
I found the Diablo match to work really well. Cutting cards is actually easy with this gun. The difficult part is holding the card. The pellet is going very slow compared to a PCP rifle. And the pellets tend to drift out of the card about half way through. I use a 2x4 with a slot cut that holds the card firmly.
