Mk85 is brutal on caps
My new MK85 blows caps to pieces and what few caps survive jam in the striker recess. I don't shoot heavy charges (70 to 90gr of Swiss) and I also get indications of striker bounce. I'm wondering if a stronger mainspring would help. This rifle was on the dealer's rack for at least 20 years and the spring might have taken a set and become weakened. I'm using the original Knight red hot nipple , which has 50 shots through it. Thoughts appreciated

Does the face of the hammer have a cone shape or just a small dimple? The surface that strikes the cap.

Flat faced. I thought my Black Diamond was hard on caps...Had an American Knight that used the FPJ's and every shot I felt like my forehead got sandblasted. Converted that one to caps and never had a problem. Got to figure it out
Re: Mk85 is brutal on caps
Wild guess, the flash hole in the nipple is eroded or too large.
The reason i asked is because ive seen the cone shaped surface do that to caps.

Re: Mk85 is brutal on caps
Could be a nipple bored too large. This one has 50 shots on it( all mine). I'd love to shoot Ampco's in this one but they're too large for the factory tool. This on has the slotted breechplug. Guess I ought to get a hex plug. Then I can shoot musket caps too.

Re: Mk85 is brutal on caps
isn't the primer strike pressure adjustable ?
