I went out today & brought home a pound of Autocomp from Cabelas. So when I got home decided to work up some .45 loads. I have a Springfield TRP that I just love and is very accurate. So any excuse to go shoot is good enough for me. I had done a lot of reading the previous posts about Autocomp here and was a little concerned about my purchase. I have a dillon 550B and I take 10 powder drops to get an average on what it's throwing before I start loading.Well here's what I put together.

10 rounds each of:

6.04gr 230fmj at 1.265" (bought some federals at this length that ran fine)
6.14gr 230fmj at 1.265"
6.30gr 230fmj at 1.265"
6.49gr 230fmj at 1.265"

Unfortunately I don't have a chrono so I can't share numbers with you.(that's next on the list). But the best groups came from the 6.14gr and the recoil was very similar to some 4.52gr WST I put together th other day. The second best group came from the 6.30gr and the recoil was just slightly more but still very manageable. The Autocomp burned pretty clean, but it's better than some of the dirtier powders out there.
All in all for target loads it was fun, but I need to find out if these loads are going to make pf for IDPA. I have a friend who has a chronograph I can check my loads with.

do yo have a compensator on your gun?

No it's just a standard Springfield TRP.

There are lot better softer shooting loads for an uncompensated .45 than Autocomp. Clays would be my first choice followed by Solo 1000 and/or N320. As the name implies Autocomp was designed for compensted guns needing lots of gas pressure to make the comp work properly meaning keeping the dot in the glass. I am using it in a .40 making 1140fps with a 155gr HP.

One of the most important things for a competition shooter is a chronograph.

Let's get something straight, I have lots of friends who shoot open guns so don't treat me as if I just fell off the truck.:steamed:
I did lots of research before buying my whopping ONE pound of Autocomp. Here are some of the results of those searches on this forum. Although the marketing is focused on compensated guns (open) the powder does not limit itself to just those guns this powder will do very well in other autoloaders. Next according to a couple of longtimers here this powder was originally a factory load powder for winchester aka smb224.
Last I know a chronograph is crucial to getting the numbers right I just haven't had the money to purchase one yet.

Maybe next time when someone posts some information about a new load and powder you won't be so anxious to "pee" in their wheaties.

Yours is the first post I have personally read from someone who is using that powder in a non compenstated gun that actually liked it. Even open shooters don't like it much it seems. I'm kinda suprised it even burned clean at low loads? Did it?

john58
04-14-2010, 16:56
Yeah, I liked the feel of the powder. I had shot some titegroup loads so I can't give you a good answer about how clean it was or wasn't. But I'll be happy to give a report about it in the next couple of days here. I also shot some 231 rounds as well. Personally I like the feel at the lower loads. But I do want to get with my friend with the chrono to see where these are running. The data in the latest hodgdons reloading annual says starting load fps is 789 but I need to get some real numbers. I'll let you know.

John58, I recently purchased some of the Autocomp myself and am appreciative of you posting your results. FWIW the only reason I bought the Autocomp is due to the difficulty I have been having in finding powder lately. I tried it in my .45 loads and felt it was just a bit snappier than my W231 loads using 200gr SWC bullets. I still need to figure out the best WinAC load for my purposes in .45acp.

I have since made a few trial loads for my S&W 66-2 in .38spl using some 148gr LWC bullets. If anyone is interested in the results I will post my impressions once I have some range time with them.

Thanks gforester, I found with the mid range load 6.49 (6.6 is max for 230fmj) the powder started to get a little snappy not much,but a little. I put together (60) 6.20's today (balance of the 100 primers left over). I'm going to try to get to the range on friday. I may put another 100 together to get a better feel on how dirty this powder runs.

I've used it in an uncomped gun too and love it. 6.1-6.2 grains with a 230RN FMJ. It feels (recoil wise) to be about 85-90% the power of factory 230gr FMJs. Very accuarte powder.

Glad to hear I have company in the Autocomp fan camp. I also noticed the accuracy on this is pretty good. And it's available!!! I've had a hard time finding WST and 231. I have about 5-6lbs of TG that I'm using to load my wifes G17. She can go thru a couple hundred rounds pretty quick.

I'm sorry you got up on the wrong side of the bed and I wasn't aware I was pissing in your wheaties. Hell you can use any powder you want I hear Longshot even works in a .45.

I didn't get up on the wrong side of the bed. How else is someone going to take "meaning to keep the dot on the target"? Well duh!!!! Or how about a chronograph is one of the most important things a competitive shooter can have?
Do you also go by Captain Obvious?:tongueout::rofl:

I've used Autocomp in my Colt DE (non-compensated) and am quite happy with it. Fairly clean and, at least in the moderate loads I've worked up, very accurate. I wouldn't try to sell anybody on this powder, but sure wouldn't discourage anyone from trying it out.

john58
04-17-2010, 13:05
Alright, I went to the range yesterday and shot 80 rounds. The groups were very tight and the gun looked cleaner than using titegroup.

Nice to see some noise from my old stomping grounds (Geaux Tigers). For 6 months or so, I've been using Autocomp for my Colt DE (non-comp) loads, in moderate 10 mm loadings, and have been very happy with the powder. It seems fairly clean and in the loads I've tried, very accurate with 155 & 180 gr JHPs.

john58, I didn't read anything by mteagle1 that you should be offended by. He was just giving his opinion that there are better powders. In addition, he provided some load data since you don't have a chronograph.

Well I might have reacted a little harsh, but if you read his post he stated some very obvious things like keeping the dot on target and the line about the the chronograph. I read it as condescending. That's why I reacted the way I did.

He was talking about how the extra gas from powders like AutoComp help the compensator in a Open gun work properly and keep the red dot sight from moving as much when you shoot. I didn't see it the way you saw it either. It's a odd powder for a regular gun in .45 really.

john58
04-17-2010, 18:01
The reason I reacted the way I did is that I have quite a few friends who shoot open guns and I understand completely how they operate. I felt the comment about keeping the dot on the target was unnecessary and obvious. I also mentioned that I didn't have a chrono in my post and I felt that again mentioning that a chrono is critical to a competitive shooter was piling on.
But hey, I'll try not to let things bother me that much in the future. Oh and for what it's worth it's a great powder at lower charges for a .45 (6.10-6.30) clean burning, recoil is very manageable.
