Maybe I will really need to run this experiment: Load up three cylinders, one with Black MZ and CCI caps, one with Black MZ and the new Remington caps, the third one with Olde Eynsford BP and the new Remington caps. All cylinders loaded with .454 cast (at the same time) balls, Sagebrush lubed wads, and Walters 0.030" 45 Colt barrier wads.
Store for 6 months and then test fire the cylinders.
Hi, three Pietta 1860 cylinders were loaded up using the Tower of Power loading tool per the above schedule. Statistics suggests a sample of six for a confidence limit of ~70%. That will work out well for a cylinder with six chambers. The cylinders will be stored in my gun safe for a minimum of six months before testing.
While I was in my caps stash, I noticed a couple of old Remington UMC #11 cap 100rd cans that were never opened. I opened one of them to find caps that have a foil lining over the primer mixture, interesting. All new Remington and CCI caps have exposed primer compound.

Hi, it has been over five months since loading up the test cylinders per the above schedule, 30gr powder by volume. It snowed this morning and since another month may find my range under snow I did the testing today. The results:
Black Mz and Remington #10 caps: 3 fired and 3 failed to fire.
Black Mz and CCI #10 caps: All 6 fired.
Olde Enysford and Remington #10 caps: 2 fired and 4 failed to fire.
Repeated dropping the hammer failed to fire the caps that failed to fire. Putting new #10 Remington caps (from the same cap can as tested) had all the failed chambers fire.
Bottom line: The problem is with the new hotter Remington caps, the powder isn't the problem.
If you intend on keeping your revolver loaded for an extended time, don't use the new and improved hotter Remington caps.
Are you surprised? I am.
Regards,
Richard
