Ruger PC and SRPs

[abbafandr]

For some reason, my Ruger PC will not ignite ammo with small rifle primer reliably.  Any ideas or similar experiences.

Fortunately i have not... But mine will not lite #41 armory primers. Regular srp no issues. Maybe you have a weak hammer spring ?

I have same issue only shoot SPP in Ruger

I believe the PC Carbine uses the same hammer springs as the 10/22.  If it does, both Wolff and Power Custom make "Extra Power" hammer springs for the 10/22 and that could solve your problem.

While some folks have used a 10/22 trigger group with the PC Carbine, it does not have the same spring setup as a 10/22 in the factory setup.

Although it probably would hurt to try an extra power hammer spring...

just as an update, I ran a bunch of CCI SRP rounds through my PC Carbine last night with no issues.  I have not made any specific spring changes.

I never had a problem with the stock hammer spring, and then later the Volq TG9.  I had some Federal SRP that I ran through in addition to SPPs.  I doubt this will fix it, or you have already considered it, but I would check to make sure there is nothing preventing the free movement of the firing pin in the bolt block.
