Sorry, stupid question.
I have a whole bunch of .38sp+p brass. Using +p data in these +p cases, these would be worked up a bit more with the powder specified to give a slightly higher velocity thru a rifle, correct ?
 
"38 SP +P" brass may not be any different that regular .38 Special brass, or it might have a thicker web. Consider it all to be the same thing. One can load "magnum" equivalent loads in .38 Special brass, and the brass won't be the point of failure if it blows up.

What kind of rifle do you have?

Headstamp makes no difference. Good .38 brass is good brass, bad is bad. I've had +P brass not survive the first reload. I've had standard .38 brass last 20 firings of heavy .38-44 loads without issue.
 
38sp. p+P

you should use rifle load data for a rifle!!! A hot .357 in a pistol [ reload ] may/ could blow up a LONG barrel .357 rifle. Is your rifle rated for p+p ???? If not , I dont think I'd try it.... being I dont know for sure ,I'd check a reloading manual....

What???
 
Every case manufacturer that has addressed the +P vrs standard case designation says there is no difference between +P brass vrs standard for .38 spl and 9mm. The +P is for load discrimination and not an indication of a heavier or stronger case.

38 SPL+P has no difference from the standard 38 SPL, other than headstamp designation for load segregation. This is due to the fact that our standard case design will handle +P pressures with no problems.

This isn't true for all +P calibers as can be confirmed in this from Starline product description for .45 Auto +P.

The 45 Auto+P is a strengthened version of the 45 Auto with the same external dimensions. A thicker web and heavier sidewall at base strengthens the case in potentially unsupported areas. This case has approximately 2 grains less internal water capacity than the standard 45 Auto.

"My +P brass only gets loaded +P. It makes it easier to keep it sorted from the regular stuff"

THIS is what i was asking about. I'm aware in this caliber the brass is marked +P to differentiate it from a regular 38 load. So i just wanted to load the +p brass with +p data and shoot it thru a rifle, like any 38 sp round could be shot thru a rifle. Thats why i said sorry,stupid question. Now that " 3 leggeddog"has mentioned it, is there some type of prohibition against shooting +p 38s thru a rifle ? I've been assuming ALL 357 rifles will shoot .357 AND 38s with no problem; AND 38+Ps thru the same rifle. (rossi 357 w/24" tube)

Opps , I thought you was asking about a .38 cal rifle NOT a .357 mag. rifle! needed more coffee,lol ... Does anyone even make a .38special Rifle? I know for sure that you can fire .38P+P in a my Ruger .357 mag pistol..Sorry If i confused anyone...
 
The hottest .38 Special +P loads can be shot in any .357 Magnum, handgun or rifle.

SAAMI pressure limits:
.38 Special = 17,000 PSI
.38 Special +P = 18,500 to 20,000 PSI
.357 Magnum = 35,000 PSI

So as you see, you are correct, any .38 Special or +P loads can be shot in a .357 Magnum chambered firearm.

...but if they are too short, they will give you fits trying to chamber them from the magazine without jamming.
 
THanks guys, EXACTLY what i needed to know. Not worrying about feeding from mag as i single load.
