[QUOTE="MudRunner2005, post: 1383292, member: 12995"] Just my thoughts, and I'm no pro, but I think powder burn rate might have a big factor on the fire-cracking part. The slower (cooler) burning powders might have slightly cooler flames, which will lead to less/no fire-cracking. And of course, proper cool-down times. It's just a theory, as I have no proof of this. As for throat and rifling erosion of some barrels and not so much on others, I think it's a combination of the barrel's steel type (CM, SS, etc...), bullet construction (how thick the jacket is, and what the alloy mixture of, or material, the jacket is made up of), and how hot the barrel gets while shooting. When steel is heated, the molecules start moving around faster. And when they get moving around fast enough (from high heat) steel can easily be manipulated, cut, and eroded (think of blacksmithing, or oxy-acytalene torches). So, as the bore gets hotter, even a more malleable material (like copper) can eventually begin to slowly erode the much harder steel. This is also just a theory. [/QUOTE]
