I've been having issues with my model 11 not firing occasionally(10 times or less in 400rds). It's a model 11 hog hunter

action with model 12 .204 barrel. All reloads and all Rem 7 1/2 primers from vastly different lots. I get an indention from

the firing pin, I can recock and try again and still get nothing. I've checked the firing pin protrusion and I'm within spec of

what people have posted here, length of the spring while compressed was checked also and it was good. I'm not sure if I

have a slightly bent firing pin, a weak spring or what I have going on. I've got a picture of all the primers that didn't fire and

a few of them look kinda weak. Any suggestions would be greatly appreciated.
