Bent skirts on those pellets tells me that the lead is soft [softer than CP Domes or HPs]. The softer lead makes for less chance of pass throughs and more energy dumped in the target/squirrel. I have straightened some skirts too. It all good.
I'd like to try some Phillips heads. No mixing those up.
Yes, I saw those - very interesting. Maybe it would help prevent some of those pass-throughs.
TJ, welcome to the GTA Forum. Once you have the required number of posts, I would like to see some pictures of those groups [if you have any.] We are big on pictures around here.
Jerry, it took me a while to locate these pictures. I should have posted them earlier in this thread.
