Question on .357 magnum and standard primers

[Winger Ed.]

Do you have any small rifle primers? Thought that spm primers were equivalent to sr primers.

I'd have to look it up to double check, but I think rifle primers are a tiny bit 'taller' than pistol primers.
But I've used them in .357Mag before too, and they did fine for me.
If anything, the primer sat flush instead of being slightly recessed in the primer pocket.

Large Rifle are taller than Large Pistol, but I think all small primers are the same dimensions- roughly.

There is no need for magnum primers with tite group or unique.

Yep

For small rifle/pistol primers they are the same size. Large rifle nd large pistol are different heights.

That is my understanding at least as far as CCI primers are concerned.

As long as I can remember 2400 has been my go to powder for 357 & 44mag. Never have used a mag pistol primer . Never have wanted for more power or accuracy.

Standard Winchester primers are made to ignite graphite coated, double base ball powders.
