Primer soft impact

[David LaPell]

I took my T/C Contender .35 Remington out this morning. About half of the ammo did not fire, and it seems like the firing pin is just not striking the primer hard enough. With my .45 Colt barrel though, every round factory or not goes bang. The ammo I shot today is Winchester factory 200 grain. The pic shows a fired round on the top, and an unfired round on the bottom.

Drop a loaded round into the barrel (barrel removed from frame) and see how deep it chambers. The chamber could be cut too deep. Or you may just need a Wolff heavier hammer spring. Rifle primers are harder (need more hit) than pistol primers.

Step one, especially in cold weather, is to thoroughly clean the action and lubricate with a light oil like Remoil. Old grease can slow down the action considerably. Then go to the other considerations if you still have problems.

You know I used to be able to pick up on this stuff, I took the TC to my local gunsmith who has told me that he has replaced alot of hammer springs on these guns. This being an older first gen Contender, it has the firing pin that needs to be unscrewed when you want to change it from rimfire to centerfire. He tells me, "wel it was backed off by two and a half turns." Maybe that was it. You know I used to catch things like that, I must be slipping.
