Pretty sure you are fine. Most modern guns can handle +P loads

I have shot thousands of 38+P out of a 357 without issue

I'd I am understanding you correctly and he has a .357 revolver, then it can easily handle a .38 +p load.

To put things in perspective:
Max spec'ed pressure for a .38 special cartridge is 17,000 PSI
Max spec'ed pressure for a .38 special +p cartridge is 20,000 PSI
Max spec'ed pressure for a .357 cartridge is 35,000 PSI
Even the .38 +p+ cartridge, which is vaguely defined as "greater than 20,000 PSI" would have an extraordinarily impractical ways to go before it approached the 35,000 PSI limit of the .357 frame. So he should be just fine with any of those :-)

Yes.
Thank You Very Much Guys ! I had more details in the first time I wrote the question.
I feel better telling him it is OK now , with these opinions backing me up.
Much Appreciated !

Learn something new every day. Now I know I can shoot those outta my Ruger revolver too.

Likely if 357. Maybe you can do me a favor and use it to shoot this laptop.

Most modern .38spl revolvers can handle +P. All .357 revolver can handle +P
For that matter most modern handguns period can handle +P

Well Francis my Speedfeed LE 870 forend comes in tomorrow :-)

sounds like a tinkering day :-)

I'm rapidly accumulating boxes of parts and no time to tinker :-)

:-)
luckily it's a piece of cake to break an 870 down. unscrew cap on end of mag tube, pull barrel off, pull forend removing bolt assy. tada lol.

I wish that pulling apart and redoing the barrel nut on my rifle was that easy. Still need to get an upper receiver vice block...

Then I gotta decide what to do with the gas system on the 20" upper.... cut the A sight down with a dremel... or stick on a low profile adjustable block and try to tune the rifle down to shoot softer.... :/

personally I'm going to cut the sight block down. Main reason is it'll be pinned on, much more secure than any screw on. :-)

mmm, bloody hell, the man makes a good point... although I personally don't have any problem with a clamp style gas block (really, I prefer it, I don't like the pinhole in the barrel potentially messing up the harmonics), but since the A block is ALREADY pinned on there, the hole is already there... and thus I don't want to lave the hole unsupported, un filled... Guess the JP block is going back to midway.... (picked one up when I could, figured I had 60 days to send it back)

You could sell it online too ya know

Just hit your block with a dremel and then some cold blue

I actually found a S&W AR 15-22 at a gun shop? I snatched that thing up, what a hoot! I haven't had this much fun with a gun in a long time.

They're starting to become findable... I saw one in my local shop last week. In hot pink tigerstripe camo :-)
But seriously, see em online from time to time at the big stores, prices have gone up about $60 over what I paid for mine.

Fun though aint it? Love my 15-22, quite happy with that purchase. If you've got the cash, stick a slidefire stock on it and a set of the $10 JP yellows springs. It's a blast. You're next stop will be Black Dock Machine for a drum. If they ever reopen. GRRR >_<

our local store has them for $400

I actually want a pink one for the wife. And yea I'm thinking slidefire for it eventually.

It's FUN. I was honestly regretting a bit as I put the parts together and thinking that I was putting nearly $900 into a .22 rifle.... but damn if that didn't disappear the moment I started shooting it :-)

Most youtube vids / guides out there talk about all the tuning you need to do to get it to work, and usually involve a $200 trigger job. You don't need to do that!

These are all I needed to get my slidefire working. $10.49 http://www.midwayusa.com/product/579...-reduced-power

That, and halfways decent ammo. I have a case of old remington bulk .22, the really shitty stuff. And it runs in the gun just fine so far, in semi auto. It even works in slidefire as far as having enough power to actuate the stock. But it jams every 5 rounds or so, round half stuck in the chamber. Not the fault of the slidefire, just the fault of the junk ammo not being able to cycle things fast enough I think.

I havn't done comprehensive ammo tests, but I can say for certainty that the CCI tactical .22 ammo works just great in slidefire (good luck finding it right now though). I'm reasonably sure any mid range+ ammo will work, although I havn't tested it yet.

The only other thing I did for the slidefire was to spray a little silicon rem oil on the buffer tube to give the slidefire a slick surface to work with. $10 springs sure beat buying a $200 trigger any day :-)

oh yeah, and if you do buy a slidefire, get it from sportsmansguide. Cheapest price I've seen anywhere for it.

just got shipping notification for the umbrella lower :-)
