[QUOTE="swampratt, post: 3344956, member: 15054"] Agree DO NOT crimp cast bullets. Bell the mouth slightly to start the bullet into the case and I run some of my cast loads through a Lee factory carbide crimp die.. but I do not crimp .. just run them through the carbide ring to remove the flare. BUT some of my Carbide crimp dies the ring is too small of diameter for the case thickness and the bullet diameter. Saying that IF I use the carbide ring it will swage the lead bullet down in size inside the case. If I need .452" some thick wall cases will leave me with a bullet that is .449" inside the case. Pull a loaded cast bullet and measure the diameter. Too hard of an alloy will not bump up into the rifling grooves well and can shoot poorly. Gasses blow past the bullet that is not seated in the lands well. These gasses can strip the lead off the bullet..Yours are Powder Coated and should be a little higher heat tolerant. I like to cast a bullet that is a bit soft if I powder coat them.. not pure lead soft just a tick above it. Wheel weight clip on type is too hard. Unless it is 357 mag gas checked in the 1300+ fps area or rifle loads 1400-2100fps gas checked and then it works well for me with hard wheel weight lead. I mix 1/3 wheel weight to 2/3 soft lead for pistol stuff. Slow 30 cal mouse fart rifle loads pure soft lead powder coated works very well. Fast powders for pistols to get the soft lead to bump up quick. Red Dot for my slow rifle loads 600-1400 fps 30 cal. Questions: Are those velocities posted above made with different amounts of powder? Or is the velocity gaining as you shoot? If it was mine I would also try the 200gr cast bullets if you have any. I would also try 231 or HP38 powder and I would try Bullseye powder. My 45 Colt did not like the heavies..I have that Lee 452-255 and the colt did not care for it. It loved the 200gr TL lee best..Go figure. My 45 acp pistols love that same bullet 200gr TL. Pull a loaded bullet check diameter of pulled bullet. Have you recovered a shot bullet..Are there rifling grooves in the sides? If it is all scratched up and no grooves it is sliding and not engaging the grooves. But that will be easily seen as the bullet will hit the target sideways. 2400 powder I would not use [/QUOTE]
