My son and I just returned from a 3 day deer hunt/camping trip. Prior to going, we spent several days at the gun range. He was shooting Pyrodex, myself black powder from 2 separate containers, one a few years older than the other. We had no problems with either powder or Pyrodex igniting. After the range we cleaned both guns in similar fashion, both getting a final, light swab of Bore Butter.
in camp, I realized I had forgotten my sons pyro, so he loaded 70 grains of the older Goex FFG black powder (which performed perfectly at the range) topped with a Great Plains conical bullet. He used a new percussion cap, bought the week before and tested at the range.
I loaded my rifle (we both were shooting .50 caliber Hawken style ) with 70 grains of black powder from the newer container (it, too, had performed flawlessly at the range), loaded the same bullet as my son and used the same brand cap from the same container. Every component we used we had range tested the week before and every component worked perfectly.
weather during our hunt dropped down to 13 degrees and on Sunday it snowed lightly all day. We did not have muzzle condemns on the guns, nor have I ever used one. However, at the close of hunting on the second day, we went to fire the guns to unload then, neither charge ignited, only the cap snapped. So, we are trying to figure out what went wrong. Both batches of black powder has been tested at the range, the can of caps had been tested, we loaded the same bullet, cleaned the guns before with the same products. I’ve been hunting with muzzleloader for about 50 years, not a newbie. But I don’t see why neither rifle fired. Any advice, ideas or theories? thank you.
