I have not bought the gauges but I need to sell a few things so I can get them. also is "fixing" the spacing possible? If so how would you do this?

What are the numbers on base of the shells? Some of the older 40s ammo that's being sold now tends to cause hard extraction and will split at the neck and some even worse. I've experienced this myself. I've also had newer ammo split at the neck too. Headspace hasn't been the cause with any of the rifles this has happened with. I have the whole set of gauges. All of my rifles and my shooting buddy's rifles pass both field and no go headspace checks. If by chance the headspace is off usually swaping the bolt head corrects it from what I've been told. Pictures of the splits would be good to see.

Now that's nice. I have yet to find a Dragoon or Ex.

I will take a picture of the two that cracked. but the sticking did happen with the silver bear ammo I bought from the range.

ok here is a picture of the casings that split. they look like every one else splits.

Yea, the common situation with this ammo, it's not your rifle, it's the ammo. Not a serious problem, but is irritating, and can direct some gas into the receiver and into your face so wear the shooting glasses.

yeah I wear safety glasses when I shoot. so should i do anything with the sticky bolt or just deal with it?

If this is the older ammo 40s-50s surplus, the sticky bolt is most likely because of this ammo. That's why I asked what the numbers are on the bottom of the cases. The headstamp. The older 40s and 50s stuff seems to cause hard extraction in no matter what gun you use it in. We've had this happen in a number of rifles and as soon as you switch ammo it is gone. I did this to test the theory and loaded 5 rounds of the 188/47 I have on strippers. It started to stick on the second round. I then loaded 5rds of newer surplus, 60/85 and the problem imediately went away. Same with other rifles. Just make sure the chamber is nice and clean. Otherwise it's just the way this ammo is in my experience.
