[QUOTE="RT2506, post: 692629, member: 10178"] Your problem is most likely using the wrong bullet lube. It takes a special bullet lube made for black powder to KEEP THE FOULING SOFT. SPG or Lyman Gold are two good ones. I make my own out of 50 % bees wax 40% olive oil and 10% STP oil treatment by volume. Melt in a double bowler and mix well. Black powder and equivalent stuff leaves a HARD fouling in the grooves and causes the lead bullets to strip out of the rifling and they will key hole. I have a 18" twist Sharps 45-70 and shoot Lyman #457193 405 gr style bullets that actually come out 418 grs from straight wheel weights with outstanding accuracy with true black powder FFG and Cartridge grade and also Pyrodex Select. Fill a case using a 24" or longer drop tube to let the powder settle and stack up good until you reach enough to allow you to place a 30 thousands thick Walters wad on the powder and then compress the powder about 1/10 of an inch with a piece of dowel rod and final seating of the bullet. Once you find this amount then you can weigh your charges to be consistent. Black powder is not like smokeless. The exact weight is not all that important but volume of space filled is very important. It needs to be compressed some to shoot well also. Use a hot primer like Fed 215 also. If you want to find out if it is your bullet that it the problem get you some Accurate XMP 5744 smokeless powder and use 28 grs under your 405 gr bullet. If it key holes it is the bullet. If you want a good 500 gr bullet the Lyman #457125 is a good one. [/QUOTE]
