Split neck 6x284??
Fellas, here's my question i'm shooting a custom 6x284 on a rem 700 action with a 26" heavy Kreiger bbl. however the question relates to reloading. I am using new Norma 6.5x284 brass necked down with Redding dies, the problem i'm having is a BUNCH of brass is splitting at the neck BEFORE firing, it has to be happening during seating of the 107 SMK, that is the place I believe the problem is occuring. I have found about 20 of the last 100 that I have done are split, am I going to have to neck turn these cases? I didn 't figure necking from 264 to 243 would be enough to require neck turning, or do I need to use a bushing die? Any help would be great, I've been reloading for ~10 yrs & have never came across this problem with my 22-243.
Thanks in advance- Outlaw6.0
