rifle primers in place of pistol magnum primers

[NOSHMJ]

With the current primer situation, Im looking to see if anyone used small rifle primers in place of small pistol magnum for .357mag?  Same goes for large pistol mag and large rifle for .44 mag.  Any info would be appreciated.

SR will work in SP but large Rifle is taller than large Pistols and will not work properly without brass modifications. This argument was already discussed here. Depending on the powder and bullet weight your using in your 357 they should light them off fine.

Hi,

 

Like Farmer mentioned, generally SR will work in SP but I tried Murom SRM in a SIG P320X5 and they would not ignite, not a single one and I made sure they were seated well. In a Walther Q5 about 10% failed to ignite (even by the 2nd or 3rd strike). Just FYI in case you come across Murom small rifle magnum primers.

I've used SR in my .38 light loads and my .357 hunting loads and never had an issue. I've also used them in 9mm before, but just make sure you're not running some super light hammer spring or something like that.

Thx for info.  Itll be for a Chiappa Rhino.  I use SRP in place of small pistol for 9 major, but figured it wouldnt hurt to ask about magnum.

I have always (since the early 90's) used small rifle primers in my major 38 supercomp loads (lately CCI 400s). I'm about to start trying CCI 450 small magnum rifle primers, I'm hoping they also work just fine.

I use LR in my 44 Special all the time with Trail Boss and they work fine.

I have used WSR and Federal small rifle in 38 special, 357 magnum, 45 acp small primer brass, 32/20 Winchester without any problems.

SPM and SR are pretty much the same primer.
