I have been trying to get my s and w m-24-3 44 special to shoot some rcbs 44-250 K . Am loading 8 grains power pistol right at 1000 fps. wheel weight Lead is with a touch of solder, bhn is 14 according to my Lee tester. I've sized and lubed with lyman lube to .430, the same but also alox coated, and lastly unsized at .431 but only with alox. All lead as they enter the bore. Bullets look great. Is this a bullet problem or possibly a forcing fine issue? Thanks
