[QUOTE="3006savage, post: 255355, member: 12069"] I doubt the bullet weight matters at all if you are using the same powder. I think the biggest factor for barrel life in a particular cartridge is the burning temperature of the powders you choose. The throat erosion is caused more by heat than the bullets bearing surface. Some ball powders claim to have cooler burning temps and they should extend barrel life. I also would expect heavier "compressed" loads to produce more heat than a 75% filled case and be tougher on the throat. [/QUOTE]
