I'm very semper sadface at the moment.
My 1861 Springfield (rep) won't ignite. Flash hole is clear, I just did a deep clean with a pan of warm water and a couple drops of soap, using a patch to "pump" it through. Circulates perfectly. (followed up by drying EVERYTHING with patches in the bore and compressed air thru the flash hole, then a patch with WD40 to displace any possible remaining moisture followed up by more dry patches till they came out spotless)
Put a bit of powder in, primed it, pushed a patch down on top of the powder, and nothin. Cap went off fine (all I have are the 4-tab ones "for reenactment") but at this point I'm convinced the caps just don't have the fire going all the way to the powder. It did have enough energy to blow a bit of powder out the second time i tried it without a patch, but no ignition.
So do I have shit caps, or shit powder?
Powder does ignite fine when I pour a tiny bit out and hold a lighter up to it.
