I have several thousand Lake City & Federal Cartridge once fired cases all processed & primed ready to load. The cases were sized, primer pockets swaged & the brass trimmed to 2.005 & miked to make sure they are correct. After tumbling clean, they were all primed with WLR primers. Powder is 47 grains of W-748, which when settled, fills the cases up to the bottom of the neck.
The projectiles are Hornady 150 gr fmj with cannelure. Now here is where the problem shows up. When seating the bullet into the case, the cannelure is sticking out above the case lip by 0.100 when the round is 2.800 C.O.A.L. I want the case to be crimped in the cannelure, but to do this, the bullet has to be pressed 0.150 deeper into the case causing a compressed load. I'm not sure if that is a safe load.
Prior to having changed projectiles from 147 gr fmj to these Hornady 150 gr fmj, there was no problem; but those projectiles are no longer offered in bulk of 1500 per case. Also, the original loadings were with BL2(c) powder, which has no bearings on the case volume as it was slightly less volume. Any ideas as to how to fix this other than buying projectiles with a cannelure in a different location?
