Annealing brass will help.. Is this new brass that you size/load/shoot/size/load/shoot and it splits the neck, or has it been loaded many times already? Also are you running max pressure loads? Even my 300 rum running hot loads(230 Berger @3200) I normally get 8-10 loads out of a set of brass...but I anneal every time...I rarely split a neck, my biggest case killer is small internal cracks starting just above the case head junction...second to that is primer pockets opening up...but even that is rare...

I should find a couple hundred rounds of steal cased to break this rifle in before I go diving into the reloads. |

How much bigger are the necks(non-split ) after firing? You shouldn't see split necks from two firings.

Having spilt/cracked necks on Hornady 6.5 Grendel brass is very unusual. What dies are you using? Supposedly the Lee 6.5 Grendel dies over work the case necks. I have no first hand experience with Lee 6.5 Grendel dies just something I’ve read. I use Dillon case lube with good results with my 6.5 Grendel brass. If your 6.5 Grendel brass is taking a beating you could cut a coil or two off your ejector. Your 6.5 Grendel might be over gassed which can ding up brass.

My Grendel is a baby on brass, it barely stretches, and only the primer pockets have opened up. I have not had a split neck yet. Hotter rounds I have for sure.

I didn't have any split necks on the Hornady brass I loaded about one dozen times, but did have a few case head separations/cracked cases. Using Forster ultra match dies.
