jmc, Thanks for the reply. The bores on my gun are .731" both barrels, entire length. Can someone hone .002" on a barrel? Seems like such a small amount, .001" on each side. On the barrel wt. #, the finished barrel wt is right on the #3 wt. for a 30" barrel. Does backing in mean they are probably #2 wt. barrels? Randy
