light primer striking problem

[floydthecat]

I’d agree with Mike that very early on, short cases were the issue here. The minimum case length is 1.280, but that assumes the action is not longer than a field gauge measurement and you can take your pick of gauge lengths from 1.299 to 1.302.

I think actual factual accurate head space measurements are very useful to determine the condition of the action. The OP might not even have to ever trim his brass as long as the case length doesn’t exceed his head space. 1.284 is not much longer than 1.280. Likely could guarantee better performance with longer case-lengths.

I am still waiting for someone to produce evidence of a ruptured spec-loaded carbine case due to long head space.
None have surfaced that I have heard about. The carbine chamber is completely supported and as long as the brass is spec…….very unlikely to experience a rupture. The carbine will very likely stop firing before a case would be exposed enough to cause a rupture due to long head space.
