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 wouldn't shoot them in an alloy framed .38 Special (I know I'm the one who posted that data, but that was 2 1/2 years ago based just on a Quickload calculation) but I might load it in .38 Special brass and shoot it in an alloy .357 Magnum. It would probably be great loaded in .357 brass (maybe even upped just a little) for a reduced-power Magnum load.

ETA: I went back and looked at it again in QuickLoad and it looks reasonable, depending on the seating depth of the bullet. So it might be a good load. But it's way above current published loads for .38 Special. (but so is 5.0 grains and higher of Unique) I still wouldn't use the Bullseye load in an alloy-framed .38 when I can get to the same place using Unique or Universal

FBI Lite 10mm,
I heard that somewhere referred to as the "Feeb load", as in "feeble".....

I've wondered if there is a "magnum" version of this load for the 357 in 357 cases.
I've done that very thing with both the .357 and .44 mags, using Hornady's swaged LSWCHP bullet in both. You can easily get to 1150 fps in either caliber using weight-relative data for several powders and you can always call their excellent tech folks if you're working with a bullet not mentioned in their published manual.

Around 1150 fps the hollow point blows open, rolls back and good-sized shards of lead depart. This leaves the bullet shank, now a full-caliber lead stump, which penetrates on in a straight line and for a good long ways, retaining about 70% of its original weight. My limited and unscientific tests involved three gallon jugs of water, backed by an old heavy catalog backed up by a tree. I'd occasionally slip a weathered 1x6 between the jugs, for variety.

Hornady's LSWCHP is invariably harder than those used by the Big 3 ammo makers. I could never get them to expand at FBI load velocities. Goosed to 1150 fps however, these would make good hunting bullets for deer-sized game; I've also left my revolvers loaded with them for defense. (please spare us the legal lectures this time) The bullet shoots very well at at these speeds but keep in mind it was intended for about 200 fps less velocity and it may lead some pistol barrels. I had a great time experimenting with them and I only wish such a bullet was available for the .45 Colt.

So what's the rule going beyond published data, do you just slowly work up till you see messed up primers or sticky cases?

Gun blows up, then back off .1 grain

Alliant's web site:

http://www.alliantpowder.com/reloade...26&bulletid=30

is not showing as high load data for Bullseye and Unique as is being suggested here. Be careful out there.

Now I load 7.1 grains of Unique under a 158 grain GDHP, but it is for use in a .357 magnum J-Frame. Be sure your gun can handle the loading ... start low and work up.

You're not looking at the right page, you need to look at the .38 special +P page... that's the equivalent of the FBI load.

Alliant shows 3.9 gr. of Bullseye yielding 874 fps vs. 919 for Unique. I think Unique is a better powder for the higher velocity rounds, Bullseye is a lower velocity target shooting powder known for accuracy, not speed.

I'm going to try that powerpistol load. 6gr is supposed to get me 1037fps.

I'll chrono that next to my HS6 load and see what wins.

Be sure to post your results when you complete the test.

You can generally rely on pressure signs like that for rifles, but it starts to get dangerous when you try to rely on those kinds of signs in revolvers. Chambers that are close to min. SAAMI spec and very smooth usually won't give you sticky extraction even when pressures are well above max, for example.

Wow great thread. FBI loads are some of my fav to duplicate and shoot. Esp in my Colt Diamondback 4". That Blue Dot blue blast... there is nothing like it in my opinion when it comes to modern wheelgun shooting.

Just back from a day of testing. I tested a lot of stuff but here's some interesting results of my .38 Special loads. Calculations were 5 shot averages.

First up is the standard pressure 158gr LSWC with 6.2gr HS6 (6.3 would be max)

S&W 642 1 7/8's" ---818fps---234ft/lbs
Ruger SP101 3"-----823fps----237ft/lbs
Ruger GP 100 6"----972fps----331ft/lbs

Next is the +P load with the same 158gr LSWC with 6.0gr of Power Pistol

642---------------876fps-----269ft/lbs
SP101------------933fps-----305ft/lbs
GP100------------995fps-----347ft/lbs

Just for kicks I tried the famous Buffalo Bore +P 158gr LSWCHP out of my long gun.
Yes I would use this to hunt white tail after this data.

GP100------------1157fps----469ft/lbs

And just to show a fancy box doesn't make better ammo I shot some Winchester PDX1 with the slick nickel cases and the bonded 130gr bullet. Oooooo!

642--------------875fps------220ft/lbs
GP100------------1013fps----296ft/lbs

So I think I found a winner here. The standard pressure HS6 load actually had more felt recoil in my airlight frame. This would be perfect for non +P pistols like old colt's. The Power Pistol load really impressed me. I didn't expect those kind of numbers. It's not quite a Buffalo Bore load, but the recoil is much less and the power is impressive.
