Help me gunboard gurus. I took me old SMLE to the range yesterday. I have recently acquired a lot of surplus ammo, head stamp RG 53 7 If I've done my homework thats manufactured at the Radgreen factory in 1953 and is standard Mk 7 ammo. I haven't shot this gun much and not at all in at least 7 years.
The Problem: when I was picking up after shooting (maybe 100 or so rounds) I noticed that some of the brass had small splits at the neck area and looked as if gas had escaped, burning a small "V" at the ends of the fissure.
Is this indicative of a head space problem or could it be chamber related? Could it possibly be ammo related? I dug up the Remington Factory Ammo from the last time that I shot and it doesn't show any signs of the problem.
Please help I kinda like this old gun.

Same thing happened to me with 1943 Australian ammo. More than likely it is not your chamber, but the brass.

I'd go with the brass as well. 50-70 year old brass gets brittle. I've had this problem a few times, only with the old stuff.

Cheers,
Matt

Thanks fellas, I was getting worried. Now I just have to get this thing to where I trust it for hunting.

They are right, old brass, brittle; neck cracks, little gas escapes a ways.
Nothing to worry about; just be sure to clean that corrosive residue out.
