small rifle primers in a pistol round?

[keppelj]

That's curious. Vitavuori calls for small rifle primers to be used with N110 for .357 mag loads. Anyone want to swap some SP for SR? 300 or so? I've got SP but can't find SR.

There is a point of diminishing returns in relationship to velocity in regards to excessive pressurization.

Rifle primers are taller than pistol primers. The primer pockets are deeper in rifle cases. About 30 years ago I tried using rifle primers in 357 mag loads. The primers were sticking out enough to bind the cylinder on a stainless blackhawk revolver.

NO; LARGE rifle primers are taller than LARGE pistol primers. This is NOT true for small primers, for which the external dimensions are identical.

If you had primers sticking out of cases that take SMALL primers, you did something wrong.

I started to scratch my head too, when he mentioned 357 mag

Well I'm flush with SR primers and have just a few SP left. Anyone ever try to use a SR in a pistol cartridge?

Me too - they're Sellier & Belliot - found that 1 in 20 FTF in a my much used Marlin U/L.
Maybe my Marlin needs a new spring?
