1941 Winchester .303

[Alan de Enfield]

Some years ago (I reckon it'd be around the turn of the century) Kynamco / Kynoch did a run of Mk7 but with NC so it would be Mk7Z in reality.
Unfortunately being S&B brass meant it was not reloadable.

I still have a few boxes tucked away.

Apologies for the quality of the sectioning - its not a bad job for an angle grinder, a rusty hacksaw and a big hammer.

You have obviously never reloaded S&B 303 brass.

We had a competition at the club to see who could get the most reloads out of it - the record was 3 (a total of 4 firings) the majority failed on firing the 1st reload.

About 5 years ago I was firing next to a friend who had 6 case separations on the trot with S&B brass; he had apparently been unaware of its reputation!

Right....that way...I get you.

Not unlike Federal brass here in the US.

I refer you to posts #8 & #12 in this thread.

Comparisons of Winchester and Mil spec (PPU manufactured) brass.

Seems to me a longer bolt head would be just the ticket for those too-skinny Winchester rims!

With that sort of thinking you'd need to keep a box full of bolt heads in your range bag and fit a different one for each brand / lot that you use.
The problem of minimising your bolt head using 'thin rims' is that when you do use some mil-spec ammo you won't be able to close the bolt.
