Hey Thanks for the Advice. I do need to get some Ackley Books. I ran a 7-RM Case through it, that's how I got the Shoulder width. It's not anything I will ever use, I just wanted to know what it was. I guess it's just part of my Collection.Run a 300 win mag case into it and then you’ll know. There are so many short 270-300 mags out there. Get a copy of P.O. Acleys handbook. Almost any magnum case on a 270 bore is overbore...
Honestly, the term overbore barely applies to anything smaller than the 50BMG.Run a 300 win mag case into it and then you’ll know. There are so many short 270-300 mags out there. Get a copy of P.O. Acleys handbook. Almost any magnum case on a 270 bore is overbore...
