Primer piercing and recoil pad

[Seth Mackay-Smith]

Naturally the battery on my calipers is dead. Will post OALs tomorrow; thanks for the suggestion.

Seth, on the LOP, I use Galco slip on's, and add to the distance needed by cutting and inserting diameters of old mouse pads. I just trace the butt, and cut the number I need. On a good gunsmith, I use Gunther Pfrommer, located near Roanoke VA. He has done work on many of my side x sides, including my 1884 hammer. A great craftsman. Pfrommer Gunworks

Thanks, Jay, I'll get a Decelerator and do what you and Bruce suggested. Appreciate the word of mouth on Pfrommer, too; I'm hoping for someone I can go see without burning the whole day but if he's that good then that may just be my day Friday.

Thanks Jerry. That makes sense. I had a pierced primer on a nice V Hammerless 16 owned by Dick Dow. Thankfully they were his shells ! The gases went through the hammer hole and blew out through the trigger slots on my finger. The stock cheek also cracked.

Investigation surely continues. I have been shooting everything under the sun, reloads, factory shells by Winchester, Remington, Federal, RST, Gamebore, you name it, and I have not had a problem with any shotgun, hammer, hammerless, you name it. Good luck with the search for the culprit, but 65 years of double gun shooting has not resulted in similar problems in my experience.

I used to get pierced primers pretty regularly on two of my T/A hammer 16's - one more often than the other - and almost all were on the left barrel/hammer/plunger. All were cheddites.

Have a Remington hammer 12 that I made a new left firing pin, it pierced Cheddite primers and I shortened it 3 thou and no more problems.

Seth, it isn’t so much they use Cheddite primers, as that they use Cheddite NPEs.
I don’t know if Cheddite even sells unprimed hulls, but that would be a costly step for RST to add priming new hulls to their operation.

[Seth Mackay-Smith]

Sorry, I see that I was unclear-what I meant was that the thin wall of the Cheddite primers, which I would think are what's in Cheddite NPEs, seems to allow the piercing or tearing of the primer wall during firing instead of the usual deformation. But that's just the internet and my impression!

Gentlemen:
For what it's worth, I quit using Cheddite primers long ago. I switched to Federal 209s, cut my powder charge by half a grain, and have never had another problem with cup piercing or ignition.

The upshot is that I don't have to modify a classic gun to accommodate a lousy primer.
