Rem. 38spl+p 125gr. golden saber

LOL, I have used my scanner once or twice, (after several attempts), I feel your pain. Yes, absolutely I would be interested in the formula. I appreciate that you are not an 'expert', this way even I can understand, thanks again.

BALLISTICS FORMULA - FOOT POUNDS OF ENERGY

Jamie:

here is the formula. Hope you are good at math - actually it's not that difficult, just a little bit of algebra.
IF YOU CLICK ON THE FORMULA A FEW TIMES YOU CAN ENLARGE IT.

MINOR CORRECTION TO FORMULA

Jamie:

The formula is correct, but the results in step 3 are in JOULES, not Newtons as I have typed. Not a big deal, but there are some picky guys here and I want to make sure the terms are correct.

Since I did not make the revolver, I will give you the answer that S&W gives to their customers..................

If the gun has a Model number stamped in the yoke area when the cylinder is opened, then yes you can shoot +P ammo from time to time. (ex: 10-5)

Buffalo Bore states the following:

BB ammo that is +P rated will function fine in any modern revolver that is rated for such, as their pressures do not exceed SAMMI specs. for that cartridge.

Hope that helps......

With a caveat. Buffalo also states:

"There is such a variety of 40 S&W pistols in public use that we will not determine what pistols are compatible with which 40 S&W +P loads - this is your responsibility! We will add that this ammo is safe in pistols that use a fully supported chamber."

By the way, they also warn against using their 45 in a Taurus Judge.

Did they invent a secret new powder or are they just actually pushing towards magnum pressures? I'd be careful.

My question exactly. I don't worship at the alter of hyper velocity, but I am curious. My guess would be a powder optimized for a particular barrel length and use the max safe charge before returns diminish. Or unsafe. All the manufacturers include the disclaimer that your gun better be in good shape...

Personally, I'd rather have 7 milder rounds COM than a couple of Big Boomers in the floor...

I agree, seeing the velocity claims from Buffalo Bore made my eyes open, (there are plenty on these forums who back up the velocity claims). What really made my eyes water was when I went on Double Taps site, DAMN!

 

[chief38]

What will REALLY make your eyes water is if and when you actually Chrongraph the BB loads against the Big Three loads PERSONALLY out of YOUR gun and see what a huge difference there really is. The recoil is not all that different and is very controllable.

I was a bit skeptical at first, but when I did the actual testing myself (as opposed to reading it on a forum or in a magazine) I was just blown away. You will never go back to the Big Three stuff for self defense!!

Buffalo Bore® is simply the best IMHO.

Buffalo Bore® is simply the best IMHO.

speed doesn't mean much if they don't open:

Buffalo Bore 158gr (non +P) SWC-HC

 

[Jamie]

Hard to argue with that, but then I haven't personally tried 'em out. Might have to look into getting a chronograph, what a GREAT excuse to go to the range!
(Can't wait to see where this thread goes now )

Badge130:

I just want to point out that the data you posted from Brassfetcher was for BB's NON +P loading, NOT the +P data we were discussing.

Yes, bullet expansion is important, but IMHO it takes a back seat to penetration. Expansion is not much good if a bullet does not reach vital organs. A shallow expanded bullet may tear and destroy tissue, but more than likely, won't put a bad guy down instantly like a vital organ hit.

The other interesting theory here (regarding the NON +P BB loading) is that if the bullets did fragment into 3 different pieces after penetrating 14 inches, is that necessarily a "bad thing"? Seems to me that it would actually inflict more damage to the body internals than a single projectile.
