Maybe this question isn't a great fit for the gun project subform... I recently rechambered a barrel that had previously been a 7mm Shehane. I cut off 2 1/2", the entire old chamber and the new chamber, a 7-6.5 PRC consumed another 2" of rifling. The round count before rechambering was 560.
After the new chamber was cut, I could not tell by looking with a borescope at the lands and grooves that the barrel was not brand new.
Would you expect this barrel to speed up over the first 100-150 rounds as usual or is that effectively pre-completed given the barrel's history?
Thank you,
Hank
