[QUOTE="Craig Dodd, post: 159146, member: 4127"] I have a 6.5 Baer (pretty much a 6.5 STW)with about 350 rounds through a 1:8 Krieger barrel. The barrel, epoxy monted in a bedding block, is 32 inches long and 1.250 full length. Inspection with my Hawkeye borescope shows about 3 to 3.5 inches of heat cracking. the rifle is still occasionally delivering 1oo yard groups in the .4 to .5 range and 200 groups in the 1 range, but will sometines shoot groups double those numbers. A while back there was some discussion about rebarrel or cut it off and rechamber and goodgrouper mentioned using something like the Tubb's Final Finish bullets to fire lap the throat area on a "tired" barrel. My question is given the 3.5 inches or so of heat cracking is it realistic to expect much barrel life extension through fire lapping the throat? Kirby, goodgrouper and others, what is your take on this? I did see that Tubb's offers both a "Throat Maintenance" kit as well as their bore lapping kit. Thanks, Craig Dodd in sunny SE Idaho [/QUOTE]
