I just put together two rifles in 6.5x55 Swedish Mauser. Adams & Bennet barrels on sale for $89.99. I hand finished the chambers with a PTG chamber finishing bit to acceptable tolerances using appropriate GO NOGO gauges. I am using Norma brass in both of the rifles and during load development I identified a confusing issue.
One barrel is ok with brass trimmed to 54.85mm but the other needs the brass trimmed to 54.45mm or the bolt is VERY hard to close. COAL for both using Hornady seating tool is the same for both (2.965" with Sierra 120 gr Pro Hunter (Twist of 1:8.5)) I even checked the projectile necks with layout fluid to look for marks and 2.965" is good.
I need to talk to PTG about the chamber finisher because it came with a ding in it that leaves a ring on my brass when fired. You can see the ding with the naked eye. My burning questions is: Is the chamber finishing tool supposed to cut forward of the shoulder and advance the neck also? What happened? Anyone else got any ideas (other than buy a more expensive barrel)?
Once I got the brass length issue identified I can now shoot 3-5 shots inside a nickel at 100 yds.
