Large Pistol Primers Vs. Large Rifle

[LawrenceN]

Has anyone ever deliberately or unintentionally used large pistol primers in rifle cases and if so, how did it work out for you?

 

[Deathrawt]

The cup depth is shallower on one of them, large pistol I think?
So if you used a large rifle primer in a pistol case it wouldn’t seat as deep
I remember reading something about it somewhere

one is for pistol one is for rifle the burning rate is totally different one ignites large amount of powder 40to 70 grains of power fee and one 14-20 grains how would they interchange

I’ve used magnum large pistol primers in a 45-70 contender carbine with great results. Have played with it in several 30-30 rifles and a few more 45-70 rifles and all worked very well.

Used them in 30 30 large magnum pistol worked good

I use large magnum pistol in my 30 30 they work perfect. I can't tell the differance in accuracy

A small pistol magnum is allegedly similar to a small rifle standard and dimensionally the same.

I think deathrawt is onto it... I have read the same thing. I have all the large primer variations but havent ever looked at them side by side. Maybe I'll pull em out and take a pic. I think I was reading about it in regards to using a primer pocket reamer that the pistol and rifle large primers do not interchange in depth.

Large rifle primers have thicker cups, to withstand higher pressures. Using a pistol primer in a high pressure rifle cartridge can result in a ruptured primer, which can damage the bolt face.
