trading primers

480 ruger calls for a large pistol primer, higher chamber pressure than a 7.62x39, 6.5x55. I use Winchester LRP for cast in any chambering I have that calls for a large primer. Still have plenty of large rifle primers if I need full house loads.
 
They work fine in cast bullet loads (think lower velocity,lower pressure). I certainly would not use them in high pressure loadings in a rifle.
 
I would not fire a jacket rifle bullet in any rifle caliber using a large pistol primer ..... exceptions would be Pistol caliber rifles

even some 357 mag will flatten reg pistol primers

i Used them Federal #155 with my HI Press 44 Mag handgun loads - 21.5 grs H110 with a 300 gr-er ! Shot them, in my M1894 Marly - All Good - Everything was FINE ! WHY you THINK there might be a Problem ? thxs RJ
 
I've used Winchester large pistol primers in 303 and 6.5x55 without issues. I need to also say that I don't load "hot" loads, just in the starting load range.

With all due respect , the 44 mag is a pistol cartridge designed for pistol primers.A hot 44 load, even if fired in a rifle, is not what I would be worried about. Someone loading hot in a 30-06, or 300 mag. might "experience things differently" so to speak. That was where my concern lay. Hope this clears things up. ....catnip
 
Large rifle and pistol primers are different heights. Pistol are about .01" shorter. You'd run the risk of light strikes due to either firing pin too short if you seat them all the way to depth, or the firing pin seating them the last .01" if you've seated them shallow and not having enough energy to ignite them. Depends on the gun I guess. That's not considering the pressure issues you might have.

You can sometimes get away with using small rifle primers in pistol loads as they're they same height.
 
I would never substitute pistol for rifle primers or vise versa but that's just me, they may or may not work, there is a reason that they make different primers for different applications, it would be simple if there was only large and small, use them for everything and Bob's your uncle
 
Years ago, I had an oversupply of Large Pistol Primers, so I started using them in my 30-30 loads.
Never had any issues at all, even with full power loads [30-30 is not a high pressure cartridge]
No misfires, and no pierced primers over about 2000 rounds total. Dave.
 
I’d consider it in low power cast loads. I’ve got some low pressure pistol powder 45/70 cast loads that you’d easily get away with a pistol primer. An adjustable seating tool would be a must though. I wouldn’t just bottom the primer out. I could see an issue if the pockets were questionable as well.
I also wouldn’t go on record recommending it… When you assume common sense is present, you can for sure steer people into trouble.
