I am trying to develop a load for my 6.5 cm
Using Eric cortina method from yt. I prepped a case and seated a projectile very long. Applied some lube and loaded it into chamber to find jam length
Results where 2.276 cbto
Using a hornady oal Guage and thr modified case I pushed as hard as I could on the springy thing to the point where the bullet what light embedded in barrel. Popped out projectile re inserted into case and measure
Results where 2.211
Those are wildly different. My only guess is that maybe in method one the bullet is stuck in the lands and is pulled out of the case slightly on extraction. Thoughts.???
