Has anybody used Accurate #5 for 45acp. My LGS has a pretty good supply of it and I am tempted to by some. I have used it for 9mm but not 45acp
 
I started using it in 45 a few years ago but that was when it disappeared. I wanted to use whatever I had left in 9mm so I quit. Certainly performed just as well in 45 as it did in 9mm. I pretty much use it in every pistol cartridge that I reload.
 
AA#5 is a great powder for full power loads in 45 ACP with 230 grain jacketed bullets. I load Rem and Win 230 FMJ's at 8.1 grains for a nice accurate load safe in various brass with CCI 300 and RP 2 1/2 primers. With 230 gr. Hornady XTP's I load from 8.1 up to 8.3 grains of AA#5. Some load from 7.9 up to 8.5 grains with 230 gr. bullets. I would be careful and work up when going above 8.2 grains with 230 gr. jacketed bullets in your pistol. Haven't used it for 185 or 200 grain bullets. Consult several reloading manuals as max data does vary between them. Accurate data online.
 
Been using it since it came to the States back in the early 80s. Never ever encountered a problem using it in my 45_Series 70. A little faster burn than Unique no doubt a whole lot cleaner too. Excellent powder for reduced cast lead loads. Plenty of zip when its needed for personal defense also. One thing that was never a issue. I change out my recoil springs quite often. Hard ball Soft ball. The series 70 always functioned regardless of its #5 charge weight..

I took it up to case failure and down to fail to cycle, I should have taken it all the way down to stuck bullet.

AA#5 In .45ACP

This has become one of my favorite powders in pistols. 7.75 grains underneath a 200 LSWC has been a just-can't-miss load for me. Accurate, easy recoil and pretty clean burning. Feeds like a charm thru a Uniflo. It works great in 9mm as well. Give it a try!:D
 
Greg for all intended purposes they are interchangeable for data, and results. While I would not mix them together, I would use data for weight, and volume the same for both.


To the OP lucky you being able to find much of that powder. It seems to be the only one not on the shelves around here.
 
I have too. AA#5 prefers a little more pressure than 45 ACP; but it still makes good rounds. I've loaded hot 185's with it that did well. But overall, it likes pushing the heavies (230's) better.

If you're loading fairly stout rounds, grab the AA#5. If you're just building range fodder, you might want to look for something a little faster.
