Fired four groups of 5, 30-40 KRAG reloads. 150 grain pointy Hornady bullets. Roll crimped at the canular.
I got the empties all mixed up, but I assume it was the last five split the shoulders. Not positive but it makes sense.
I didn't notice till I got home. (That will change) I always look at the primers as I unload the cases.
My hottest was 38.4gr of N-140 for 2160 fps. and that's not near the maximum.
The splits were very similar. I plan to repeat with different cases and round nose 150 gn bullets to see what happens.
So my question is what that splitting indicate all on its own?
