Cracked Necks?????

[rafsob]

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.

You wouldn't have to do that. Any reloader should be able to measure a fireformed case shouldnt' they? Every reloader should have a set of head and shoulders gage along with calibers and even a set of mics.

Man, its like 25 dollars. I have seen people go thru hours of playing around and troubleshooting when I came over with a tool and showed them in 5 min. Some people have more time I guess than others.

How much do you think a gunsmith with charge? Gas getting there? etc?

Holy cow, is that a sentence?

New cases don't split on the first firing unless they were imprperly annealed from the factory. I've saw this with unfired new ammo before 3 out of a box of 20 were split when purchased from the factory.

My canuckeese (grins, so don't get mad)is kinda rusty but let me try to translate.....

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
