I recently purchased a Ruger No 1 in 6mm Remington.

After I got it home I took it to the range with some FACTORY Winchester Super X loaded with 80 gr. bullets.

The accuracy was ok but had one problem.

A moderately flattened primer and pronounced offset ring all the way around the cartridge at its base. the ring is NOT perfectly uniform
either. The offset is more pronounced on one side of the cartridge.

There is no black smoke around the primer and the firing pin hole is not cratered or pierced.

Also this is my first No 1 Ruger so when a cartridge is chambered should you be able to see the top part of the rim on the case??

My GUT feeling is that this is an obvious sign that the rifle has been over loaded at some point in time damaging the chamber??



I contacted the person I purchased it from and he claims this is perfectly normal because this is a high pressure round and that his brass fired frome the rifle is in the same shape. To be fair to him he is claiming that the rifle was always like this as he purchased it from another individual. I The rifle dates back to 1972 so it could have had MANY owners over last 33 years.

I am going to take it too a gunsmith to have chamber measured and rifle checked out ASAP.
