[QUOTE="Kevin Thomas, post: 1155707, member: 15748"] Pardon my joining the party late, but this one deserved an answer; it's a most emphatic YES! Bullet weight plays a significant role in barrel life, with heavier bullets being harder by far on the barrels. Case capacity, velocity, pressures and so on certainly play a part in the equation, but bullet weight in and of itself is a major factor in regards to accuracy life. My own contention here is inertia, and the fact that it simply takes longer to begin moving the heavier bullet down the bore. During that time frame, as brief as the time spans we're talking about may be, the high temps and pressures have more time to wreak havoc on the critical leade/throat area. This is based on having shot out hundreds of barrels over the years, with the entire range of bullet weights in any given caliber. [/QUOTE]
