Have been getting a lot of split case necks only on Remington 6.8spc  brass on the second or third loadings. I try to lube the interior and exterior of the necks when sizing but I do size maxed die on the shell holder under compression. I do not own a gauge to check the cases to set the dies any different.
No other brand brass seems to be splitting and I am wondering if the problem is the brass, my method of sizing, the barrel chambers neck, the brand cases, or a combination that might be causing the splits necks. Any input would be appreciated. Thanks

It is not hard to tell when the cases split they have a distinctive ring to them when they hit the concrete.

I don't load Rem brass in my 6.8, but annealing may be the answer with it.

I do SSA and SSA made ( rebranded ) and Hornady only. Still saving enough Hornady to use for Match brass or something in a small batch, but with SSA I personally have a batch of 50 cases I've used for load development that I've loaded 9 times, from mid book to several grains over book max and have yet to have a neck split without annealing.

I did have a batch of SSA cases I loaded have a split up the the body, but, that was traced back to setting the shoulder back too far when I first switched from a RCBS RC press to a Hornady. I caught it during load redevelopment and fixed it. No problems since.

I use RCBS SB dies, and Frankford Arsenal spray lube.

My method is to take 100 cases outside sitting in loading blocks made from the plastic trays from 45acp pistol ammo , with 100 in a bag inside, spray a squirt in the die, go outside and spray the cases all around, from every angle. Bring them in and let them sit a minute.

Put a lubed one in and size it, the pull one from the dry bag and size it, and back and forth. It keeps from denting the cases and you'll never stick one. Smooth as silk.

That's awesome dryflash! Might havr to make my own "poor man's" annealing setup too!

Dry do you anneal all your rifle.

Thanks for the replies. The annealing is too much effort for me so I will probably just reload them the once and trash them after that.
