New Brass, .243 Cracked neck
Hello everybody. I just pulled some brass out of the tumbler a few hours ago and found that over 50% of the rounds my wife shot this weekend cracked at the neck. This was new WW brass, I ran through a new set of dies, trimmed to spec and primer pockets uniformed. I used Hornady One Shot spray lube this time around and have read this may be part of my problem but I still want to get some different opinions. I have enclosed a few pictures although only one of them turned out somewhat clear. I hope somebody can shed some light on the issue.
Any opinions will be valued as this is my wife's rifle and she is new to Shooting and hunting and I don't want to start her out with a preventable incident caused by my ignorance.
The load is Winchester Primer, 40gr IMR 4350, pushing a 87gr Vmax. It is a light load that is extremely accurate and great for getting her a feel for the rifle. I was going to start bumping it up as we get into deer season since she got a doe tag in her first ever drawing.....(another story there as I have put in for 10 years with not a single draw)
