RolinB...
Thanks for the welcome... I'm sure much of my conundrums came by mere happenstance or stupiidity, but then it may have been fate...
I did find in that somewhat short PA season it a bit of a PNA to load it fresh and then head out...
We did all manner of stupid stuff in that time like black balloons over the muzzle, although most will tell you a patched ball should seal the powder main charge... we stuck feather quills in the flash hole or touched them off before we left...(only season where you could discharge a weapon after dark and not get heat about it.) Being an ornery GERMAN, I opted to discharge, then clean when i got home and reload at 3AM before heading back out... (NO wonder bows seemed so much simpler)(stickbows at that)...
I'd bought a TC Firestorm that was reputed to shoot pellets but I got it for the removale breech plug... RMCmade one like that but the TC was cheaper and I had little play $$.
When RMC sold out the price trippled to what they're worth today, but the TC never would fire pellets well...Oh, they went off, but I joke that you'd touch off the pan powder, bend over and tie your shoe, come up and take hold of the gun before it went off... (Might be a bit exhagerated, but not much... then I tried loose BP and it was flash-BOOM ... I read a Ross Seifried article suggesting opening up the removable flash hole liner and drilling it out and coning i... I opened it some, but the first time I loaded it standing in snow and shot it just went POP... With the removable breech I could check the bore and it was clear...then I glanced at the snow... most of the main charge lie on the snow... :
... From then on I'd use a quill to hold in the main charge as I rammed the patched ball home, but that was the gun that in the field, it flashed and no boom... it has a cone shapped SS Breech plug and I'm sure the main charge either got behind it or it got quite chilled (up north) and the heat / Fire never reached the main charge but those things were beyond me then...suffice it to say it was "retired" and I hunted with bow or handgun's thereafter...
Now I have the GPR 50 and have re-learned a lot, alas too late smart and too soon old...
After 2 right shoulder surgeries that curved buttstock proved a pain but I learned to make a leather covering and inserted some super gel gifted me and now it's only a small problem to shoot but I reduced the main charge to 70 gr. of 3F vs. the 100 I did shoot in my TC's...they printed the same as whatever was recommended that escapes me but the 100 gr. load under 75 yard printed 8" higher so I used it instead...
