So I had to check after seeing Calum's photos of his primers....here are mine, and I have now some questions

Now, the two on the right are rounds that were chambered by letting the bolt fly forward, or by having it pick up the next round after pulling the trigger. Both were ejected without firing for inspection.

The one on the left is a normally fired round....I seem to recall something known as a "cratered primer", and if my memory serves me right, that is what they look like :eek: Is that bad? :eek:

Now, for the two on the right; we all know that milsurp ammo (at least the stuff I am using) has hard primers, sufficient to avoid most problems of a soft pin strike. Let's say I decide to take my SKS gopher-shooting and get commercial soft-point ammo....will it become a problem?:confused:
 
Let me know how the commercial soft point works for you. My d won't feed it at all, the points are too soft and they catch on the face of the chamber.

I think the only way to get a hollow point that will feed properly is to load your own without any exposed lead.
 
I never had any problems at all with handloads (federal primers, known to be soft), commercial or milsurp. I had a Yugo, and it wouldn't even mark a military primer like that. Keep the firing pin clean, and you should have no problems. If you do, you can order a set of Wolff gunsprings for it, that might help.
 
A cratered primer can also result from a loose fit between the firing pin and firing pin hole. Your fired case doesn't look particularly bad, I've seen worse.
This firing pin bounce is the reason that SKS and AK rifles have flat tipped firing pins - reduces the chance of a round being fired as the bolt slams shut.

Well, thanks for that info! PP also PMed me at my request (thanks PP) and had the same observation.

My fireing pin and channel are very clean, and the pin rattles easily inside.:)

How much are those aftermarket titanium-with-spring fireing pins? Are there any sources in Canada for them?

If I ever take the SKS in the bush, I might reload for it and use those milspec CCI primers :redface:
 
Here is a pic of the hungarian surp stuff that I shot today.

This is from a SKS-D and you can see marks from the pin but not hearly as deep as some of those posted. Also no cratering.
