With Black Diamond BBs I get the groups below.
Full auto jumps around a bit and I'll need some practice to tighten that group.
I've shot almost a thousand rounds with the Black Diamonds without a single jam or misfeed.
I tried the plastic BBs and had endless misfeeds.
Also, the groups were much larger ... all over the paper (8.5 x11 sheet).
Lead BBs weren't as accurate as the Black Diamonds but they too, had lots of misfeeds.
