Hey everyone, im new to the forum and hopefully am posting this in the correct area of the site. I have some pietta .36 navy's and the Chambers measure .367-368, with groove to groove diameter at .372, wondering if anyone out there reams cap n ball cylinders and could help open up my Chambers over groove diameter to about .001 over, so to about .373 . Just looking to get the most accuracy out of my navies. Heard of others doing this and it helped a bit with closing up their spread. Thanks to all in advance.
