What is the distance to lands average in coal for this bullet? I am getting 2.396 with the hornady tool. Used a dowel from the muzzle to feel for the bullet hitting lands so I'm confident in the measurement.

2.366 + or - with a Sinclair tool. The polygonal rifling is a bear to measure if you use anything besides the Sinclair System and I have used five other methods with poor repeatability. Ritch and I measure them independently and are within 0.003 in 95% of the time. You are way in the lands at that measurement.
The reamers have not changed since we started doing the 264 LBC.

I can understand that the poly rifling combined with the profile in the amax might cause issues. But this would be the same for both tools. Other than using a fire formed case with the sinclair tool I'm having trouble understanding how the measurements can be that far off. I have used the hornady, stoney point tool and found it to be close. The main difference being the headspace difference in the supplied case and a fireformed case.

My suggestion is load some up with various powders at factory lenght of 2.60 and go shoot some. They have been shooting factory Hornady very well. I've been shooting the Noslers at 2.310 out of the ASC magazines.
