primers

[Tigerstripe]

lets hear some talk about primers.

im wondering if small rifle could be interchanged. shooting IPSC a friend used a 38 super. he claimed to use small rifle primers in his loads. he may have used magnum small rifle.

i know 38 super is a different animal. he claimed he could get more out of them than factory 357. doesnt seem posible with half the case but he said his 38 super were 1850 fps to a 357 1300 fps. been a long time, it was something like that.

what about using small rifle in 9mm? for lack of small pistol primers.

and switching large pistol with large rifle?and vise versa.

9x19 has similar operating pressure to .357 or .38 Super (34,000PSI v. 35,000 v. 36,500 for the .38 super). So the theory might hold.

I wouldn't want to fire the first round loaded so out of my own gun, though

but what would the pressure be using a small mag rifle primer?

 

[dride76]

I have used small rifle primers in 9mm I've always used the baseline. Never max them with a higher pressure primer. I have heard small rifle primers are harder and handguns that have light strikes could have a problem. Never had a problem with any of mine

someone should email federal or cci and find out specifically what the differences are. To avoid the standard 'never use x primers in y' legal disclaimer say you're shooting pistol caliber in a carbine - like a Marlin Camp Carbine in 9mm or lever gun in .357...

I'd do it, but I'm on the phone all day today anyway.

Found this:

While the diameters of both rifle and pistol primers are the same, the height is not. It is not unusual to see small rifle primers loaded in handgun cases for exceptionally high pressure loads. Examples would be the super magnum handgun rounds, such as the .454 Casull, which typically uses a small rifle primer. Another would be their use in cartridges such as handloads for the .38 Super when pumped up to make major velocities in practical shooting. But that doesn't work with large primers. The large rifle primer is too high to seat in a pistol case.

I have a friend that does a lot of competitive shooting locally and uses small rifle primers in 9mm and .40 caliber. Just REGULAR primers, not magnum. Like Dride76 said, the small rifle primers are slightly more firm than pistol primers, but never had a problem in my Glock and have seen them used in a 1911.

I have only been reloading for about 12-to 15 years and I have loaded with small rifle primers almost always in 40's 45's 9mm's...all you get is about 10 to 15 fps faster,if loadem,or send all you can get to me to I will do away with them for you
