Cracked Necks?????
I am having a problem with cracked necks in my .25 WSSM cases. I had two testloads of 18 cartridges each and when I was finished I ended upwith six cases with cracked necks. Some hadsingle cracks and others had two cracks. One had three cracks. At this rateI will be going throughquite afew cases. Oh I forgot to say the cases were all new Winchester cases and one once fired win case.
I reload for my .300 WSM and have not experienced this problem with those cases. Is this something unique with the smaller cases?
I have been loading since thelate fifties and have not had this problem with any otherreloads. I have hadsplit military cases thatwere old (.30 Carbine ammo),butnever commereical or reloads.
What the hell is going on or am I doing something wrong withthese WSSM cases? Help!!!!!!!!!!!!!!!

I have not experienced this ever until I get to around 5-8 firings. Have you taken out you expander ball and measureing your sized case and then put the expander back in and then measured? It sounds like your sizer is overworking the neck. But it would have be alot. Have you tried any collet or bushing sizers?

I would take the rifle to a gunsmith and have your chamber measured. Good luck.

Can you tell me what cases, bullets, dies, loads, and rifle you are using?
What was the air temp?
Were the cartridges in the sun?
Can you tell me how to prepare new cases because we screwed some up one time.
I'd guess his name is Dan.
Just trying to help.........lol

Most factory chambers are cut with .006-.008 per side--safety isssue I guess...that's alot of room around the neck..that's also alot of room that will be filled when the shot goes off and also alot of stretch..poor quality brass sometime will crack and especially after 2-4 firings... size some brass just enough to hold the bullet and see what happens..an 1/8 of an inch will do, I'll bet the brass doesn't crack.. I shoot all my factory varmint rifles like that, accuracy is outstanding, haven't had a case stick and haven't had any problems.
