[QUOTE="gregw83, post: 2789421, member: 77352"] Hey all, haven’t been on the forum in a while, so I thought of a good question to get feedback on. I have a Savage M12 LRP in 243 win. It has about 270 rounds through the barrel, so I decided to get the oal gauge out and remeasure to see where it was at. Of those 270 rounds, 200 were 70gr blitz kings over 41 gr of 4064, and a box of factory ammo for barrel break in when it was new, and a few test loads. I found that I’d now have to seat them out about .015 further to reach the lands now. I know the 243 is well known for being rough on barrels, but is this within “normal” wear, or is that excessive for 270 rounds? It’s not a real concern, it’s a savage, so I can rebarrel it on the living room floor when I shoot it out, but I’m just curious [/QUOTE]
