Thanks for the replies fellers, I'll go down the list of questions : Gemmer, the guy I bought it from said he sent it to Hoyt a few years ago for re-barreling. I have no reason to doubt him and I can see no sign that it might be lined. Mr. Bodner, I'm using new RWS 4 wing caps. Some CCI caps did the same thing. Charlie Hahn, the bottom of the nipple hole was flat but the flash hole to the chamber was drilled down through the nipple hole and is at a steep angle. The fire has to hit the bottom of the nipple hole, spray in every direction, then when it hits the wall of the hole where the fire channel is drilled, it turns about 70degrees downward for at least 1/4" to get to the main charge. I just did some "shaping under the nipple so that now the fire coming out of the nipple hits the sloping surface of a radius that ends at the mouth of the flash hole. I drilled away about 1/16 " to lower the entrance of the flash hole then used a ball end mill to make the radius. Maybe it will help. And Mr. Cobb, I bought two new nipples thinking maybe the one that was on it when I bought it might be burnt out, but there is no difference in any of the three I have. I've shot this gun about 150 times over the past week. And yes, I understand about clearing the fire channel. Iv'e tried everything including flushing it with alcohol, drying it and popping several caps. Nothing I have done has relieved this aggrevating spatboom little hang fire and plugged up fire channel for more than three or four shots at a time. Out of 20 shots I'll typically get about half a dozen hangs and any time I wipe the bore, I run about a 50:50 chance of stopping it up so tight that no number of popped caps will clear it. Take the nipple out and either dribble a tad of FFFFg under it or take a pick of some kind and rod out the hole. I've been using the shank of a fish hook for that. I had ideas of using this gun at Friendship but I'd spend too much time trying to get it to shoot. What is really grinding on my ace is this thing shoots like a house afire when it goes off! I borrowed an old Rapine 536/400 mould from a friend and made a sizer that trues up the egg shaped bullets a little and leaves them at .536". It'll shoot good with 40 grains of Goex fffg or 35gr Swiss fffg and a lube I mixed from beeswax and bear lard about 60% bw. On the bottom of the barrel is stamped .536 which is undoubtedly the bore diameter. Its scary accurate if I can just figure out how to make it reliable.
