Thanks to you all I am moving on from my Lee to a Dillon 550. I wish to use a high volume powder to help detect any double charge that may or may not happen.

I am currently using HP38 which has been pretty good. The choices I am looking at from researching are:

For 230 Grain Jacketed:

Accurate #7 9.9 grains
#5 7.8 grains
Blue Dot 8.5
Unique 6.0
Win 571 8.4

I am looking for something not too dirty and readily available. The Crossroads is next weekend and I would like to stock up.

Of those mentioned. AA #5. Accurate, clean, bulky enough a double charge is evident. I've shot a lot of it in .45, 9MM, and a bit in the .40. It is very versatile.

WSF is similar and does very well also.

AA# 2 is grey and easier to see in the case, but not as good for top end loads. I drilled my Projector for an LED flashlight which shines in the case so it is not that big a deal, but I still like powders which are light in color for that reason.

Blue Dot is going to give you more recoil for the velocity produced, but is definitely bulky.

Nothing wrong with HP38/W231. ;)

One that I really like that you didnt post is Red Dot no way your gonna get a double charge with it. Red Dot works great anyware from 4.0 to a 4.5 with a 200 lswc works great for me.

Win 231
Bullseye
Both above are great powders of the .45ACP Just pay attention when reloading on a 550, I upgraded to the auto-indexing XL-650 with the powder check system.

I like Accurate #5. Hard to double charge and meters very well. This is from Accurate's site:

"No. 5 A relatively fast burning double base, Spherical propellant developed for use in the .45 ACP. No. 5 is our most popular handgun propellant."

I like Blue Dot and Unique, but that's because it's what I've used. Both are about the same cleanlieness wise, but for economy, I'd pick Unique, you're almost 30% ahead of Blue Dot. That's a lot more rounds per pound in the grand scheme of it all.

If you're making 1000s of rounds, this should be considered. If only a few hundred, then choose what meters best is my opinion. I have found Blue Dot and Unique to meter quite well in my Uniflow. And in the 45ACP, if you double charge, you'll be spilling powder.

Not the case with Bullseye and Powerpistol type double based powders. Those will easily double charge and leave room to spare.

Unique has been my staple for the last 20 years. http://i9.photobucket.com/albums/a62/lakcaJLOpe/thumbs.gif

I use AA7 for hot loads in 45acp. No way you can double-charge. Twice 9.9 would fill the case to the brim, with no bullet room. Number 7 is a powder I actually beat factory data with, and 9.9 is not a soft load. Might be a little hot for punching paper, unless you need to make a PF.

Win. 571/HS7 has been discontinued. It and AA#7 have been powders I've used for .45 acp (and other calibers). Seem to be at their best with upper end pressures/velocities. Not "plinking" loads. I've since had success with HS-6 (Win. 540). A bit faster than AA7 or HS-7/Win. 571, but still impossible to double charge a case. 8.3 gr with a 230 FMJ gave 830-850 fps from memory. Obviously, one downside to a slower/high volumn powder is the additional cost (nearly twice as much powder).

#5 and Unique are the most versatile. #7 and Blue Dot will get you the highest velocity, but don't overlook HS-6 in that regard. It appears that most of your .45 ACP loads are velocity oriented. 231 is a very good choice, but it's not on the list. 571 isn't available, but last time I checked HS-7 still is while it's being phased out.

I'm going to sound like their salesman again, but I believe you could cover a lot of ground with Ramshot Zip. It's spherical and will meter well. Bulk density is 780 Grams/Liter, so you'll get good case fill. It burns cleaner than 231. The Ramshot data won't excite you, but Sierra's should. With their 200 grain "Match" bullet, Zip gave the best accuracy in their latest manual. The price can't be beat, so as far as volume and getting the best accuracy with a variety of loads, it might be worth a look for you.;)

I have had good results with Green Dot. Bulky, a bit slower than Bullseye and seems to meter well through a Dillon powder measure.

In my opinion, double charging is less likely to happen on a progressive than one a single stage. I have used a Dillion 550 B for more than two decades. Sure there have been times when I weighed some loaded cartridges to make sure they had powder, or were not double charged, but I have loaded well over 70,000 rounds on the thing. Probably closer to 100,000 rounds. And no double charges or empty charges to date. Keeping my fingers crossed by Gum!..

The chance for a double charge occurs when you get interrupted. Maybe the bullet was misaligned in the seating die and you had to stop and remove a crushed case. Ditto for the sizing die. Maybe the primer did not feed. Something like that. When interruptions happen, and that includes phones and friends, you have got to teach yourself to double check everything before you pull the handle again. Regardless of what you remember doing when you were interrupted. Allow doubt in your ability to remember, acknowledge that you have early advanced Alzheimer's, and follow a process, not your memory. Typically, I pull the pin on the case under the powder die, remove that and dump the powder in the measure, finish with the case in the seating die, clear the press, and start with the empty sized, belled and primed case on station two, and a new case on station one.

Again it is my opinion, but double charging is most likely to happen when using a single stage. Instead of a continuous process, such as the progressive gives you, you have this batch process. And it is in the charging of the cases where you have the greatest chance of error. I used to examine each and every case in the loading block with a Maglite flashlight, and on occasion I would find an empty. It is easy to get out of sequence when using scoops, or even the little Dandy powder measure. Maybe it was because I had too much time to daydream; whatever. Because my mind is so often in la la land, I think it is good practice to use bulky powders when using a single stage press.

Before I got my progressive I used to be scared of fast powders like Bullseye. It is well known that a double charge of Bullseye will blow the pistol. Not any more. I have my process and practices down. I have successfully loaded so many cases of 38 Specials with bullseye powder that the fear has gone away. Bullseye is now my favorite powder in 32 S&W long, 9mm, 38 Spl, 45 ACP. I just have to pay attention to my process, and double check when I am interrupted.

Buenhec, are you selling off your Lee? :D

Green Dot is my favorite 9mm powder, but Promo is a close second and it's really cheap. Both are bulky fast powders (Promo is the same as Red Dot but slightly less bulky so it meters better) that should do great in a short stubby case like .45ACP.

Yep, I am selling my trusty Lee. I keep getting told to keep it, but I dont really need two presses. If my Dillon breaks, I just take a 20 minute drive to the dillon HQ. I am asking $100 for the Lee classic 4 hole turret, it includes the auto prime (small/large) and the auto disk.

Which meters better, Unique or #5 in a Dillon. These two seem to be the most popular overall.

I thought Blue Dot would be a bit too slow for .45ACP, no?

Blue Dot works fine in the .45 ACP, but it gives a lot of recoil for the velocities produced. There are better options.

AA #5 & Unique for example. ;)

Might I suggest IMR'S Hiskor 70OX powder. I use it to load my 45acp and, at 4.8 grs, there is no way you can double charge a case. It also meters very well in my 550 press.

I'm kind of surprised no one has mentioned Herco, a fairly fluffy flake powder that used to be the go-to powder in 9mm. I've used it a good bit in 40SW, and I see no reason it wouldn't serve admirably in the 45ACP as well.

Regarding an earlier comment about it being easier to under- or overcharge a case when batch loading, I'd have to disagree. I use Lee Auto-Disks, and the brass goes from one loading tray to another, with a stop at the powder measure in between. I've been doing it that way for 15 years or so, usually 200 rounds per batch, and I have NEVER had a high/low/missing powder charge. I guess the system matters, mine is apparently pretty good. For me to use it that long without any boo-boos, I'd have to say it's fool-proof! :p
