Alright, I searched through the threads and haven't found any that quite answer my question, so thought I'd put to to you reloading gurus....

I'm looking for a pistol powder that;
-meters well
-reasonable accuracy
-and ideally works well in both the .45 ACP and .40 S&W

I've used powder pistol, but I had issues with consistent throws during metering.

Any thoughts?

Thanks....

What kind of powder measure are you using? I thought that might be useful info. I'm using the one that came with my Dillon...

WST is the best powder for 45. I'm not sure for 40 though, I don't load it.

Hodgdon (http://data.hodgdon.com/main_menu.asp) has WST data for both .45 and .40.

Sorry can't answer OP's question.

Then I'd give it a shot. I've used it in 38spl, 9mm, and 45, and it works great for light to medium loads.

Do you use a meter to measure it? And if so, is it pretty consistent?

I like unique since I can use it in all non magnum pistol loadings and even some of those I can use unique in. Most of my reloading is unique then 2400 then 4227/bluedot/power pistol.

Every pistol cartridge that I know of can be loaded with unique and 2400

I have an RCBS uniflow and and two Dillon powder measures. WST flows like water in both of them. And I'm not exaggerating, it meters really really well.

I've used Accurate #5 in 40SW and 223 loads(subsonic). My friend uses it just for his 45ACP....Shoots well in his and shoots well in mines. Im thinking you can use those for both?

Winchester 231 for both .45ACP and .40 S&W. Due to 231'a ball shape it meters very well, better than most powders.

I am using 700x and getting really accurate results in .45 and 9mm but it does not meter as well as 231. When I finish this 8lb'er of 700x I am going to go back to 231.

I am reading into this that rather than a search for a new powder you could be troubleshooting why Power Pistol is giving you variations in powder drops with the Lee Pro AutoDisk.

I use Power Pistol and the Lee Pro Auto Disk and thought I was getting good results.

How much variation are you getting?

Do you keep the powder hopper at 1/2-3/4 full like I do?

Are you using the chain return or spring return option on the disk assembly? The spring can result in a jolt that helps break up any bridging and ensures getting a full drop in the cavity. That is more a function of the powder than the equipment but I haven't noticed any flow problem with PP.

Are you using disk cavities or the "Adjustable Charge Bar"?

To address the question of selecting another powder, I believe I would consult load sources (my books and the powder company websites) for powders that are listed for both calibers. These would be your candidates, depending on what was available. You would probably want choices among what was in stock locally, so you could just try one pound.

Pistol Powder is Extruded with wafer or flake shape. I have found over the years that wafer and flaked shaped powder don't meter that well.

Lyman's 49th Edition lists Win-231, Bullseye, AA #5 and Unique as the most accurate powder for .40 S&W and .45ACP

You're going to find there are several very good powders for those two rounds, some of which have already been mentioned.

Here are two other excellent choices for metering through a Pro Auto-Disk Powder Measure: Bullseye and Titegroup. I use a lot of each, and they meter to within 0.1 gr as checked by my RCBS 10-10 beam scale. Both of these powders are very good in .45 ACP and .40 S&W. They're also very good in .38 Spl and light .357 Mag.

If I had to pick just *one* powder for all my handgun rounds, it'd be Titegroup for its remarkable versatility, even in .45 Colt. Fortunately we're not in that situation, because I just love Bullseye in .38 Special. :-)

There seems to be some science missing here. 40 and 45 are significantly different in pressure and velocity. Common loads for 45 use the very fastest burning powders, while 40 SW is often represented as better done with powders from the midrange. I think a powder to do both would have to logically come from the high side of the midrange and low side of the high range, overlapping by some number of choices. I don't think that would include Bullseye. Here is a slice from the list of burn rates that is probably about right.


20. WST (Winchester)
21. AP- 50N (ADI)
22. HP38 (Hodgdon)
23. AO (Vectan)
24. 452AA (Winchester)
25. 453 (Scot)
26. 231 (Winchester)
27. Zip (Ramshot)
28. 700X (IMR)
29. Green Dot (Alliant)
30. AS- 50N (ADI)
31. International Clays (Hodgdon)
32. 473AA (Winchester)
33. HS-5 (Hodgdon)
34. WSL (Winchester)
35. Unique (Alliant)
36. Universal Clays (Hodgdon)
37. N330 (Vihtavuori)
38. AP- 70N (ADI)
39. Power Pistol (Alliant)

A sleeper among these is Green Dot. Forced to substitute powders, it shot well in both calibers, although I didn't do any disciplined or scientific evaluations. I don't see well enough to get too particular about accuracy. It seemed fine to me. I hit what I aimed at, and my gun didn't blow up. A poster on one of the forums mentioned it being comparable to W231/HP38.

How much variation are you getting? .

Its been awhile since I used Power Pistol, but as I recall I was getting .5 to .6 variance in charges. I attested that to the large flake texture of the powder, (as I’ve had excellent consistency with other finer powders like H335)


Do you keep the powder hopper at 1/2-3/4 full like I do?

.

How full the hopper was didn’t seem to change the lack of consistency.


Are you using the chain return or spring return option on the disk assembly? .
I'm using a chain return, that I attached a spring to the end of to maintain the tension on the chain


Are you using disk cavities or the "Adjustable Charge Bar"?.
Just the disk, (not double stacked either). BTW, I’ve been thinking of getting the adjustable charge bar for fine tuning the charges for those smaller pistol rounds, how well does it work? (trying to find a disk cavity that translates to the grain value needed can be a real headache sometimes!)

+1 for Solo 1000.

Do some research on this powder. It works great for 9mm, 40 S&W and 45 ACP.

Bullseye throws very evenly, good accuracy, just very dirty IMO.

I load 4.1 bullseye for my target loads with 230g round nose moly coats @ 1.21 OAL

AIMSMALL
09-07-2010, 7:46 PM
I load the bullseye at 4.8 230g RN TMJ. I'd have to check notes for OAL but 1.2X It is a little dirty but it just works so well in my guns that it's worth it to me to clean after use.

Mac Attack
09-07-2010, 8:01 PM
I don't load .40 S&W but was looking at load data today for a friend who is starting to load .40. I do however load .45 and for years I was a die hard bullseye powder man but when bullseye was impossible to get last summer I went with Titegroup and am now a TG convert. TG will load both .45 and .40. It meters well in my RCBS uniflow and Dillon powder flow. It's clean and I noticed I do not have unburned powder all over the place after shooting with bullseye.

Revoman
09-07-2010, 8:04 PM
I suppose that Unique may work okay in both, but I have had better luck with Bullseye in 45 and Unique in 40. As stated above in at_liberty's post, the rates are different for each of those two calibers.

Cowboy T
09-08-2010, 3:58 PM
Hence the suggestion of Titegroup. As Mac Attack has pointed out, it works well at both pressure levels. Slower burning than Bullseye, but faster than Unique.

As I mentioned, if you *have* to pick *one*, TG would be an excellent choice--as would several others. But fortunately, we don't have to. Try the various suggestions listed in this thread and see how it goes.

BTW, the dirtiness issue with Bullseye may well depend on the type of case it's used in. My light .357 Magnum LRNFP load with B'eye is so clean that I don't even have to tumble the cases afterwards. My .38 Special LSWC load is very nearly as clean. But 6.7 gr B'eye in .45 Colt is so dirty it's ridiculous (TG is much cleaner there).

I was under the understanding that almost every gun reacts differently than another. If powder "A" works great in my 1911, that doesn't mean that it will do the same in yours... Your best bet is to buy a few and test them out till you find one that you like.

Unique sucks. It's a dirty flake powder that doesn't meter nearly as well as a ball powder.

Ramshot ZIP, give it a try.

Depends on the powder measure and the amount of static. Bullseye and Power Pistol are identical in everything but their burn rate.

I don't know about the .40, but Bullseye works great as a propellant for .45acp.

Bullseye is a great propellant for anything, but only in moderation.

sleeper among these is Green Dot.

Ditto this. 4.2gr of Green dot under a Berry's 200gr SWC shoots VERY well in my 6.5" S&W wheelgun. I also tried it when I couldn't get any Bullseye. I keep a few pounds of it on hand.

VV N320 is what I use for .40 and 9mm. I use N310 in 45 acp. N320 could be used in 40 and 45.

BlackICE

I use Universal Clays for both.

In the 40SW it works great, chrono round have a very close velocities.

In the 45ACP the velocities vary more than I would like about 40 fps spread. To get even that close the loads have to be at the high end near maximum. At slower speeds it is even worst!

That said, it burns clean, low flash, and meters well.

I haven't tried it in my 357 yet, but I suspect it will work well in medium ranges loads.
