There may be something relating to a 10mm FBI load, but the one I'm most familiar with is the old .38 Special FBI load. If I remember right it was basically a +P load with a 158 grain lead SWC HP.

They should be labeled "158gr. LSWCHP". If you find them, buy them.

Magnus Bullets #515 with 4.3 grains of Bullseye will get you real close.

You guys are probably right, and the OP has been seeing that with regards to .38 Special LSWC-HP.

Quote:
There may be something relating to a 10mm FBI load
But in the event we are talking about the 10mm, it's pretty much a very tame, wimpy 10mm loaded by Federal to send a 180-gr JHP to about 950 fps. Referred to as "FBI lite." Wimpy, because the 10 was designed to send a 200gr bullet to 1200+ fps.

When you discuss the rise and fall of the 10mm cartridge in it's short history in the FBI, especially here on TFL, arguments usually ensure about how much is historical fact and how much is internet hooey and gun store gossip. That's for the end user to sort out, but the relevant points usually include the FBI putting out a contract for a new service pistol that made up for the inadequacies of the 9mm round and S&W winning the contract with the 1076 pistol in 10mm. Then... (and here's where the arguing gets rolling), for whatever reason, the idea surfaced that the typically loaded 10mm is a hot little number, somewhat difficult to control and/or handle. More arguments ensue, and then in the fog appears Federal's downloaded wimpy 950 fps JHP ammo in 10mm. S&W then says, "we can make a whole new caliber if that's all you want your .40 cal bullet to do, and we can build a smaller handgun closer to the dimensions of the 9mm rather than this 10mm monster." S&W design a pistol around a new caliber built in conjunction with Winchester... And the .40 S&W caliber is born. (then, Glock actually beats S&W to the market with the first .40 S&W pistols!)

Anyhow, when someone is referencing FBI Lite 10mm, that's pretty much what they are talking about: watered down, wimpy 10mm ammo that's no better than .40 S&W ammo. To this day, Federal's own Hydra-shock ammo in 10mm is weak, wimpy and (in a 10mm), senseless.

I would argue that the FBI-Lite is superior to the shortnweak even if the velocity is the same. The pressure is lower and the damage to hearing is lessened by the increased case volume. Also greater tolerance for bullet setback or manufacturing variances, especially with heavy bullets (such as the 180's mentioned above which Dillon Mfg abhorrs in reloaded .40 cases to the point they started an aggressive marketing campaign targeted expressly towards .40 shooters who were their customers).

But... I'm a fortyhater.

Most of the time I hear FBI Load, however, it seems to mean the 158gr LSWCHP .38 revolver round.

Hi ARMSMASTER270: Do you know a load data to duplicate the .38 Special Treassury load with the Sierra 110 Gr. JHC bullet and get some 1300 fps? At this moment I have Blue Dot powder and CCI 550 primers. The gun is a .357 M. 4" barrel.

12 grains of Blue Dot will get you close. (in .38 Special brass) 9.3 grains of Power Pistol is better; same velocity but lower pressure and more complete combustion. Both are over current SAAMI specs for .38 Special +P, but not much over.

Thanks very much for the answers. Very nice pict, expansion but no fragmentation, what bullet brand & velocity?
Excellent suggestion. Already I experimented in .38 Spl. cases with Blue Dot, Sierra 110 JHC and CCI550, COL 1,450": 12,8 gr. 1400 fps ES 34 (poor velocity gained); 12,1 gr. 1363 fps ES 33 (yet a bit hard); 11,7 gr. 1313 fps ES 71 (high ES, velocity +/- 12,5 fps x 0,1 gr. increment, same as in the Sierra manual). I would appreciate very much your guessing on pressure and general advise on the cartidge. Unfortunately is impossible for me to obtain Power Pistol powder.
Previous experimentation with H2400 give a lot of unburned powder, Unique, raise the pressure with no velocity gain. Thanks a lot again.

You are using a shorter OAL than I originally thought. 0.1" is significant here. You can't safely get where you're going using Blue Dot, but you can get sort of close. (I wouldn't load over 11.0 grains)
Code:
Cartridge          : .38 Special +P (SAAMI)
Bullet             : .357, 110, Sierra JHC Blitz 8300

Thanks for the answer. Very usefull chart with lot of information. The OAL 1,450" I use is the printed in the Sierra manual. The maximun powder charge for the future: 11,7 gr. This load is intented to be fired only in a S&W M19 .357 Mag. 4" barrel revolver. I think 24.000 psi will not harm this gun. Other data was experimental only. Thanks again.

Centurion 1945:

Slugs were from the treasury load by Federal #38F-TD 110gr JHP 15% pressure overload from 38+p fired from a 4" S&W Mod 15 Range to impact 3' as he was charging me with a knife. Clothing Tshirt and Pendleton shirt over that.
Chamber pressures for 38spl +P+ ammo go from 18,500 to 23,500 depending on Mfg.

Time to dust off this old thread because I'm trying to recreate the Buffalo Bore 158 gr +P load as well.

I have some LSWC bullets, they aren't hollow points but this is more for training so that wont matter.

I'm looking for +P data with a cast bullet and can't find much. The best data I can find so far is 6.3gr of HS-6 it should give me 1010fps out of a 7.7" barrel. I'll be using a 2" barrel so it's no where near the 1000fps claimed by BB.

I load 158 grain SWCHP's with 4.5 grains of American Select. Just because. I haven't chronographed them, but based on Alliant load data they should be close to 950 fps, maybe a little over, from a 4".

You're going to have trouble finding anything to beat 5.0 grains of Unique. That may be a slight overload, depending on what book you want to believe and what 158 grain bullet you use.

For a practice load, I use a 158 gr. LSWC (no need to pay extra for HP) with 5.3 grains of Unique. I can't distingish them from the real thing (Remington R38S12).

Steve, I just want to verify--are you using cast SWCs, or are these pure lead SWCs like the Speer product?

If your bullets truly are cast SWCs then you're fine, but if they're store bought pure lead SWCs then you'll want to keep the velocity down.

The +P data I have for bullseye tops out at 3.8gr for a claimed 954fps which would be less than the standard pressure max for HS6.

Would 4.3gr be +P+? I want these to be safe in my alloy framed 642.

I'm not sure what the make up of the bullest I'm using are. I bought them at a local gun store and they are made by a local company I assume.

I've wondered if there is a "magnum" version of this load for the 357 in 357 cases.
