Has anybody used this before. It’s supposed to be good stuff and fairly new out on the market. What it boils down to I bought a lb and there is no data for 9mm 115, 124 and 147 gr FMJ.

I went here http://data.hodgdon.com/cartridge_load.asp but it does not really help.
<o:p></o:p>
Is there any other place that you guys know where I can check.
Thanks

There are AutoComp loads for each of those bullet weights on the http://data.hodgdon.com/ website.

Might want to give that site another try, the below is copy/pasted from there:

Bullet Weight (Gr.) Manufacturer Powder Bullet Diam. C.O.L. Grs. Vel. (ft/s) Pressure Grs. Vel. (ft/s) Pressure

115 GR. SPR GDHP Winchester AutoComp .355" 1.125" 5.1 1078 28,200 PSI 5.6 1161 32,500 PSI

125 GR. SIE FMJ Winchester AutoComp .355" 1.090" 4.7 1055 28,900 PSI 5.2 1120 33,300 PSI

147 GR. HDY XTP Winchester AutoComp .355" 1.100" 3.6 827 27,900 PSI 4.0 916 32,800 PSI

Thanks for the info but I have the Berry's 115 FMJ and not hollow point and reloading for the 1st time I catch a big scary.

Start with 5.1 grs, 1.130 OAL, 115gr FMJ bullet. Work it up from there.

Autocomp is made for compensated guns. take it back and get any of these.

Powder is usually not returnable so you might as well use it with the 115gr data listed and Berry bullets are plated and not jacketed and most people use lead bullet listings.

Not true. It works well in compensated guns (because of it's low flash characteristics); but it's not exclusively for compensated guns. Turns out it was the powder Winchester used in pistol rounds.

I found the article in June 2009 of Handloader magazine (pg 26). They run loads for 32ACP, 45ACP, 38SPl, 357Mag, 41Mag, 44Spl, 44Mag and 45Colt. None of the guns had compensators.

"Now Hodgdon has turned its attention to handguns and selecting from powders used in several Winchester pistol cartridges, chosen to expand the line once again. The powder is called AutoComp. It was designed principally for use in auto-loading pistols."

"AutoComp's burning rate is in the range generally occupied by slow-burning shotshell powders, being a bit slower burning than Hodgdon's HS-6 and slightly faster than Alliant's BLue Dot. That said, the same range of burning rates frequently works well for metallic cartridges too, especially those of relatively small case capacity and moderate bullet weight. One of AutoComp's more significant characteristics is the very low level of muzzle flash, most important in low light, defensive situations, even of the training variety."

"There are several other catridges with published AutoComp data I haven't tried yet, but the picture is pretty clear. There is a great deal of potential here in both pistol and revolver cartriges."

Dudel:

All that info sounds encouraging. However, I'm at a point where trying out new powders, and going through more load development is becoming less and less appealing to me. I really do like the Winchester powder line, tho.

I hear you BB. Right now I'm happy with what I load. The M4 is new, so I do have to work up some loads for .223 (not as much fun as I remember it). Might not be a bad idea to get back in the practice of it though in case one's favorite powder is unavailable again. Might just be easier to stack your favorite powder(s) high and deep.

My main purpose in covering AutoComp is/was to dispell the notion that it's only for compensated guns.

Lack of load data support is probably the biggest problem with Autocomp. I've burned nearly a pound of it trying to find a sweet spot in 45acp. IMHO it sucks. If a person wants mouse-fart loads, use Clays, Titegroup, VV320, etc. If you want high-end loads use AA#5, PP, or maybe even RS Silhouette. AutoComp doesn't make sense for the 45acp unless it is the only thing you can find, (and that's how I ended up trying it).

Nevermind.. don't know how I missed it..
