[QUOTE="mulie, post: 2275719, member: 19271"] The barrel appears to be a button barrel? I would first slug the barrel to determine if it has any tight spots. JB bore paste will not remove that rough what is seen it can remove some of the copper. Get slugs order and slug the barrel it can point out issues, if found. Then pour a lap begin with a fine lapping compound lots of lubricant and lap if you truly feel it needs the lapping. Again TMS Tubbs will help it is much easier. I first slug a barrel to determine did manufacturing do their job? Also to determine where the barrel will need to be cut to length for best performance. Also with your borescope determine if the lead appears to be centered on the lands sometimes if they are off this can induce smearing down the barrel again this is stuff to check. Begin with the simpler stuff then if it does not cure it move on to the next. [/QUOTE]
