Jericho Light Primer Strikes?

[aridan]

I think my Jericho is as broken in as it may be reasonably expected by now, after about 600 rounds. Those initial FTE failures I've experienced seem to be all gone. The only remaining problem is light primer stirkes with S&B 115gr ammo. Out of about 100 fired today, I had 5 light strikes. Does this relate to the recoil spring being too weak? I haven't had any issues with my own reloads, go figure. My own are AIM 124gr with 4.0gr of Titegroup.

I could be bad ammo, weak hammer spring, broken firing pin or firing pin spring. If your firing pin is broken it may be hard to tell, unless you take it apart.

The pin is fine, I took it apart when I was cleaning the gun afterwards.

I never had any issues with S&B before, so I'm wondering why now? Then again, I'll probably stick with my reloads from now on, so this will be a non-issue. I just wanted to know what may be the cause.

I've heard that S&B ammo can have very hard primers. That might be the cause of your problem.
