Rifle that will not fire ????
A friend brought me a Interarms imported Italian made 50 cal black powder percussion fired rifle to "fix". He consistently gets failures to fire (after many attempts it has never fired, ever) but his "setup " is weird to me as is all this black powder shooting.
He replaced the cap nipple with one that has a 0.028 inch hole through it and is tapered from 0.163 to 0.174 inches where the #10 cap is suppose to go.
He is using American Pioneer Powder 50 cal sticks. Their web page says to use two of those sticks with the 178 grain ball he is using. Since that info is not on the bottle (2 sticks) I suspect he may have only been using one but I'm not sure.
The ball is a Hornady #6090C for 50 cal Muzzleloaders at 0.490 inches in diameter. They just drop down the barrel so he must have been using the patch material I found in his kit. There was also some pre-lubed patches which American Pioneer Powder says NOT to use since their powder is not suppose to require any lube at all.
I want to start at square one with the setup he was using unless there is a compelling reason to not use any one of his component choices. So to be sure I get it right before trying to shoot this beast I want to know if:
Does anyone sees a problem with his setup?
I did test the barrel with compressed air and the passage ways from the barrel to the nipple freely flows air so I don't think there is any blockage there. I wonder if the powder sticks are a poor choice and the problem. The company is still around and you would think if this was a problem they would be long gone since he bought this gun four or five years ago.
I have some Pyrodex P (FFFG equivalent or so the bottle says) is this "wrong" for this gun? Do I need to get some FFG old fashion black powder? The instruction manual for the gun says 90 grains of FFG or 70 grains of FFFG. Does that mean I can use the Pyrodex P? Hodgdon seems to say no and that I have to use their FFG equivalent Pyrodex .... period, no discussion.
Any help with this will most assuredly be appreciated.
