Around here pistol powder is as hard to find as 22lr. So one of the shops had quite a bit of Hodgdon Tightwad so I got a pound to test in my Gold Cup. 3.5gr behind a Saeco 200gr SWC grouped about the same as the w231 I had been using. I can find data for the 45acp and 9mm (haven't tried it in my 9mm yet). I was wondering if anyone had any info for a 38spcl loading. From my experience most powders run similar charges between the 9mm and the 38spcl. Pressure for same charge weight should be less in the 38 due to the extra case volume?? If I can't find any data I am considering working my own load up with a start charge in the 3gr range and go from there. I have never deviated from a load manual and am wondering if my logic is sound before I proceed.
Your Logic sounds good to me.
Indeed, to my understanding, the same Charge in .38 Special and in 9 mm P-'08, would produce much less pressure in the larger Case volume of the .38 Special ( assuming the Bullet is Lead and most importantly, is seated to a normal depth ).
Charges listed for 9 mm P-'08 also tended to be the same or about the same as those Charges listed for .38 ACP back when, where, in the latter, the Bullet was heavier, the Case volume quite a bit larger, and, the pressures realized, much less than in the 9mm.
I tried a few fast 'Googles' and apparently it is 'Titewad' rather than 'Tightwad', and, it is said to be about on par with 'Bullseye' for Burn rate, and, it is offered and sold a Shotgun Powder.
So, one thing which comes to mind for me, is that it may not ignite reliably in .38 Special, particularly as one would only be using quite a little dab of it in what at that point, in a fairly large Case Volume for that tiny dab to be settled down onto the lower part of, and likely settled down mostly below the Primer Hole.
It might be a better bet to work up a Load for deeper-seated heavier DEWC Bullets, than for conventional shape kinds of Bullets in .38 Special.
The only information I found was on Hodgon site that says it is a 12 Gauge shotgun powder. It is extremely fast burning. Rated as # 3 on their burn rate charge. Faster than Red Dot which is faster than Bullseye.
Purusing their load data, I see no mention of it at all in9mm,38sp or 45ACP. The only data I see for Norma R1,the fastest on their burn rate chart is about 3 gr for the 38 sp, 158 gr lead. So I sure would not be starting with anything over that.
I saw no correlation between the 9mm and 38 as the 9mm is usually loaded in the 125 gr bullet weight class and the 38, is 158 gr. Even comparing 125 gr class, I see no direction comparison of powders .
I checked the Hogdon site, and there are no loadings listed for 38 Special and Titewad. IMO when a powder company doesn't show a loading for a particular powder in a caliber as popular as 38 Special, it tells me that it doesn't consider it a suitable powder for that caliber. I've always taken a pretty conservative approach to reloading, and while I've experimented with loads, I've always started with some published data.
Powder is cheap; I strongly suggest that you keep the Titewad for you ACP, and find something more suitable for the .38.
It may well be too 'fast' for practical application on what originally were Black Powder Revolver Cartridges ( such as .38 special ) or, for early, 'longer' Cartridges of some Automatics.
If it is faster than 'Bullseye', I'd say, it is too fast for me anyway!!

I got all mine that way, and never even bothered with local sources.
I would suggest that you contact Hodgdon by phone and ask your question. Their loading website, while quite extensive, is only a small part of the loading data they have. I have been able to find some unusual loads as well as some "stay far way from" loads. An example of the latter is International Clays which exhibits some greatly non-linear buring behavior versus charge weight in some popular handgun cartridges. Don't extrapolate any load outside known data unless you like blowing up expensive guns with possible injuries or death. Just sayin'.
Went over to www.castboolits.com and found a thread with some guys playing with it in their .38 Specials and like it.
http://castboolits.gunloads.com/show...hlight=titewad, scroll through the responses as several responders had to blabber about how good a shotgun powder it is.
I prefer somewhat bulky Powders myself...

The more I brood on this, the more I would be leery of using 'Titewad' for .38 Special, unless some really definite info from Hodgson happens to show it is 'Okay' to do, and, provides Load Data for doing so.
Which, I kinda doubt will occur, since it is such a 'fast' Powder and all...it is not likely to behave well in the .38 Special Cartridge.
I read over the post on the other site and they do seem to be at the same conclusion that I have. I would buy through the mail but all the suppliers are out also
