I was talking to another reloader about the scarce Lg Pistol primers. He stated others were trying reloading rifle primers in place of Lg pistols. Has anyone else heard this, it sounds wrong.

rifle primer cups are stronger than pistol primers(a rifle firing pin delivers more energy at the primer strike )
and I believe that rifle primers are approx .006" taller than pistol,this will cause high primers
"I don't recommend this "

While I'm sure some have tried it, this should not be considered safe nor practical. Substituting a large pistol magnum is acceptable if you work the load right, but not a large rifle.

Small rifle and large pistol are interchangable--I think. A bud has used small rifle in his 45 mag.(451-??) at the directions from the loading specs. If this is wrong I will get exact info Thurs. afternoon, wc

The 454 Casull uses a small rifle primer. It is unique to that cartridge only.

This guy also stated to make sure the loads were reduced as if you were starting to work up a new load. This way they could be used safely and just as target loads, which is all I would use them for.

Can it be done? Yes.
They are the same size, thickness I would have to go caliper a few, and I'm not down in the gun room. The Cassul uses SR due to it's massively high pressures, to avoid blowing the primer cup through.
Should it be done? Preferably not.
The cups are thicker, and could very easilly cause failures to fire, unless his pistol really belts 'em hard. The thermal output of a rifle primer, designed to reliably ignite large charges of slower powders, is far higher than a pistol primer, increasing pressures. In a mid-range target load, probably not unsafe, in a cutting edge maximum load, as advised, load needs reduced.

absolutely not on the large as stated they are different rifles are taller,the small rifles are actually used in several hi pressure pistol rounds ( including the 357 maximum,the 454 casull ,and a few others)the small ones i believe are closer to the same height but there's that thicker cup and different primer compound etc thing ,try the search feature here on this , it's been posted a couple times but there's some good info as well as a chart ( sumwhere )

Small rifle and large pistol - NO. Different size altogether! SOME .45ACP cases do use the small primers - Win NT and Federal NT do - I have some. I put them aside to not get mixed into my regular cases. Trying to cram a LP primer into the NT small primer pocket could get 'interesting'......
Some rifle cases - 7.62X39 is an example - also can heve either size. RP's have a different size than Wins. I separate my brass so as to make loading life easier and safer.

Just got some Casull dies for my son's hand cannon. Already have a couple hundred cases ready so will be busy for a bit. Will be using the SR primers. If you don't hear from me again anytime soon you will know what happened-lol. wc

Just calipered a smattering of my WLR's (Win. Lg. Rifle), .127" thick, to .130" thick.
Same on my WLP's shows .117" to .120". Wolf LP's showing .117-.119" Definite height problem trying to put LR's where LP's belong. I had no idea there was THAT much difference, 10-thousandths.
IMO a pretty high risk of slam-fires in a bottom-feeder, or at least, making a jam-o-matic due to not enough headspace (for less than $29.95, and without the free Ginsu Knives and the Titanium super-peeler).
As Ordinance Spec loose as my solidly-reliable 1911A1 clone is, I am not sure it'd chamber those with that much primer hanging out the back. Jam-ups on the extractor I'd be expecting.
A perousal thru my Accurate Arms Big Red Book, which usually shows all the cartriges SAAMI pressure standard, announces the Cassul varies as to bullet maker maximum recomendation.
Some of the loads are showing 54,000psi pressures, firmly in the .308 Winchester/major rifle class round, definitely needing rifle primers.

They may be dimensionally close or the same, but the real difference is in how they are made, the pistol vs. the rifle primers are made to handle different pressure spectrums. They should not be interchanged. fg 419

Rifle primers are thicker.. this will cause a high primer problem, EVEN if they burned at the same rate, which they do NOT. That substitute is NOT a good idea !!
