The public range I used to shoot at had rules for us BP shooters:
- All powder cans where to be stored on the Back Bench.
- All loading (except priming, including capping) was to be done at the Back Bench.
- No firearms were to be Primed Until stepping up to the line.
- No Primed firearms allowed at the Back Bench.
So, once you loaded at the Back Bench, then stepped up to the line and Primed - you had to do something with your primer (or horn).
I used a small primer horn and just Stuck it in my pocket.
Never did spill any, but today if I did I would pick out Every Little Speck as if I had spilled a tin of caps!
But, I never noticed anything spill in my pocket and my pants never blew up so....
Today I shoot out on public land, no bench and the 'line' is wherever I say it is.
I load where I stand and out of habit step up to 'the line', prime and put it in my pocket and shoot...still haven't blown any pants up (BUT, I Refuse to were a Pager!!!)
