AA5744 not good for pistols.
Yep. 8.5gr of Unique under a 250 anything run great in my Henry Carbine and 7.5" Vaquero.I had the same thought.
It's kind of interesting he tested all of those powders but skipped the one with the longest and most respected history for the round: Unique. Probably because it's been done before and anybody who can type can find reams published on loading .45Colt with Unique. Still, it's got a proven track record in both handgun and rifle.
Thanks!5744 is just too slow for the 45 Colt. Even with 270 grain bullets at tier II pressure levels, you get lots of unburnt powder in 5" revolvers. My GRT ballistic program shows 22 grains of 5744 under a 305 gr bullet at 31 kpsi giving only a 67% propellant burn.
Had a Buddy just today give Me some 5744 just for My 45Colt Pistol. He said good stuff. I’ve never used any of this powder. Can You tell Me why You say not good for pistols in more detail? I hate to waste time loading them if it’s not worth it. I have other powders to use. But wanted to try the 5744 too.
Thanks!!!

Thanks Charlie!!AA5744 is the equivalent of IMR4198, I use them interchangeably (for the purpose, not charge data. They perform very similarly, but the loads are materially different) and I would no more use IMR4198 for .45 Colt than anything, either. Yes, there is data for it, and obviously there are users of it in handgun loads, but I don't see why when there are better powders for the role. Now, you load AA5744 (or IMR4198) in a rifle cartridge with a cast bullet, and you won't find a better powder for low- to midrange loads.
It’s just a load that’s uncomfortable in the revolver but awesome in the rifle. 1663 muzzle velocity and really accurate.Morning all. I’m following this because I got a RBH in 45 colt and have not loaded nor fired it yet. I did pin gauge the cyl and it’s .454, I have not checked the throat or bbl yet.
I will cast for this and will not load hot or my arthritis will keep me from shooting it again.
So Joe, no one asked about the kaboom ? Can you elaborate some which firearm and extent of damage ? Glad your not hurt I presume.
“Kaboom: 26.0 W-296/H110, 250 XTP. Deer/hog slayer.”

Not to put words in the OP's mouth, but I just think he was referring to the report of that load... which very likely sounded like a kaboom out of a 5.5" pistol. 26grn H110 is in the middle of Hodgdon's data for Ruger-only loads, so unless the pistol was unserviceable, it's unlikely it actually came apart.

That's why we got choices.it is strange that I’ve never wanted to try Unique. I’ve used plenty of Bullseye in .38 special. Now I use Titegroup instead. I guess I just thought Unique would be like Bullseye - famous from a time with less options around its burn rate.
Yeah, I don’t know what question you are referring to that HS-6 answers in the same universe where an extra grain of 231 is a concern. It was worked up to over a chronograph and isn’t near as hot as some of the others listed. We are discussing Tier 2-3 “Ruger only” pressures and velocities. I think your “warm” 7.2 keeps you under SAMMI specs of 14k. 7.3 is Hodgdon’s published max with a 250 xtp. If I were to try HS-6 (which I’ve considered) I would start well above 14k. Do you think HS-6 could produce superior velocities at less pressure than 3N37, 3N38, or N105? What are some of your favorite HS-6 loads?I would not use AA5744 in any pistol load including the 45 Colt.
I think HS-6 is the answer to your question. Remember to use a magnum primer. I tried many powders in the 45 Colt, some more successful than others. W231 was my main powder until I switched to HS-6.
Warning: your charge of 8.2 gr W231 is extremely hot, possibly dangerous. It is almost a full grain over what I would use. 7.2 gr is my hot load of W231.
Good luck...
I’ve used plenty of Bullseye in .38 special. Now I use Titegroup instead.
Never used Bullseye, although many champion it... yes, Unique filled that bill. I've also tried TiteGroup... I hate the stuff. But... different strokes for different folks... there is always more than one way to skin a cat.

I can't speak to VV powders, they are not available where I live. Do as you see fit, be safe...I would start well above 14k. Do you think HS-6 could produce superior velocities at less pressure than 3N37, 3N38, or N105? What are some of your favorite HS-6 loads?

That’s interesting that you got almost 300 fps velocity increase from a 7.5” barrel to a 20”.
