Do I have a chamber problem?

[viejorifle]

Attachment 45685Greetings:

First time on the range with this weapon. Fired 10 rounds out of a No 4 Mk 2, just acquired. Five rounds in a white box (reloaded?), came with the rifle. Also a dozen rounds of Remington .303 British.

Just learning to check my fired casings and noticed the white box ammo had two long cracks at the neck area. The Remington rounds were not cracked open, but had a lot of burnt powder on the necks.

Does my rifle have a chamber problem? Or, is it the ammo.

Were they hard to extract? just looking at the top left of your photo, looks like a "shoulder" has been formed near the base of the case.

bad brass

Is the ammo with the neck cracks reloaded military surplus cases?

I don't think you have a chamber problem. The cases with the neck cracks have probably been loaded quite a few times and suffer from metal fatigue. The shoulder or bulge at the web is likely due to undersized cases.
The soot around the mouths of the Remington cases is normal.

It may be the the lighting but are those Remington tips cast lead? If so, there're all reloads. Looks to me like work hardened brass that wasn't annealed as far as the split necks. Burnt powder residue on the neck is nothing unusual to me.

The mark on those split cases is from a full length sizing die. The cases look tired.

I,ve preached many times to individuals who have bought a rifle and where given reloads, whats in them ? you havent a clue so dont use them. Bin them and use your own or factory ammo.

Where did that ammo come from? Id clean and look down the bore/chamber, then Buy 20 new rounds and see if its repeated?

Kind of strange so many failed at once....

Couldn't agree more. I just aquired a lot of reloaded 30-06 recently and just a quick visual inspection is enough to put one off: primers proud of the primer pocket and variable seating depths of the bullets to start with. The good news is mostly Lapua brass and some nice HPBT 168gn. bullets. Well worth having but only for the components - NOT for firing.
