40 s&w 165 gn powder

I finally picked up a chronograph, and found out some interesting things.
I am using these rounds in a 9 inch long barrel 40 s&w carbine.

A 180 gn with 7.8 grains of Longshot 8 beeing max load, came out to be 1265 fps. Average fps.

A 165 gn with 7.8 grains of Longshot 7.8 beeing max load, came out to be 1280 fps. Average fps.

I did a little research on Longshot, and what I got out of it was Longshot is good for getting a heavier projectile moving fast.

I thought that the 165 would be moving a little faster.

What would a good powder be for getting a 165 gn out of a 9 inch barrel at maximum velocity?

I have a progressive press, so it would have to be something that meters well.

Thanks

Winchester Super Field WSF has been my best powder choice for 165 grain bullets in pistols and carbine rifle. Fine grained and meters fine. Definitely worth a try.

I have check my reloading powder books and only found one powder that was in 1205 was CFE 7.5 I looked at Winchester Hodgdon IMR & Accurate Ramshot That is for a 165 Gr bullet

I have been reading up on the forum here, witch led me to post a question.

Sounded like AA#9 was the way to go from reading up on it, untill I tried to find 40 reloading data.

Then AA#7 seemed to be the way to go. That I can find 40 reloading data on.

Someone stated Ramshot enforcer was the way to go, but it seemed to be a magnum type powder.

I could use a little guidance on selecting a powder.

I have CFE, Autocomp, and Longshot.
According to hodgdon longshot comes up on top just under 1200 fps out of a 4 inch barrel.
CFE is similar at just under 1200 fps

AA#9 and Enforcer are pretty close to each other and both will end up with compressed loads. Seems as though manufacturers shy away from compressed load data for handguns. Enforcer data can be found but I've never seen data for AA#9. I'm basing my AA#9 and Enforcer comparison on using both in 44mag.

In my search to make a 40 more competitive with 45s at bowling pins (safely) I tripped over Vihtavouri 3N38 data with a plated 165 which magically gave right much more velocity/energy than anything else I could find.

I’ve used AA #2 and #5. Prefer #2 as the case is fuller without compressed and #5 can be double charged (but would be very compressed and should be noticed).

I looked up 3N38 and it gets you with a max load of 9.8 grains 1252 fps. But that is out of a 5 1/2 inch long barrel.
Pretty much everyone else uses a 4 inch barrel.

Longshot with a max load of 7.8 grains out of a 4 inch barrel gets you 1,185 fps.

3N38 with a max load of 9.8 grains out of a 5 1/2 inch barrel gets you 1252 fps.

The carbine has a 9 inch barrel, and I was getting 1,280 with Longshot, maybe 3N38 is the way to go.
The longer barrel should beat out the Longshot only 30 fps to beat it.

The reason that I am on this kick, is way too much work on the house, and way too much traveling for work.

Haven't reloaded annything in about a year and a half.
I miss it, and the chronograph box has dust on it.
Reloading bench Shure needs some cleaning.
That is how life goes sometimes.

I use Longshot for 180 grain bullets and CFE Pistol for smaller bullets (155 or 165) in my .40 carbine. Mine is a JRC wIth 16” barrel. Never have run them over the chronograph, but they shoot quite good. I am using 7.6 Longshot for 180 and 7.2 CFE for 155. One of these days maybe I will chrony them...maybe.

I'm really surprised nobody has mentioned Power Pistol.

I don't load 40 S&W; but do load 10mm. And although I usually load a 180 grainer, I have loaded a few 165's with Power Pistol and got amazing performance. I suspect it would do nearly as well in the 40.

Power Pistol makes bullets go fast. I really like the stuff and use it in just about every caliber. It's truly a high performance propellant.

I ordered two pounds of 3N38.
I looked it up on a powder burn rate chart, and 3N38 comes in a little faster then Longshot.
I think with a slightly lighter bullet a slightly faster powder makes sense.

Thanks for all the help.

unfortunately I'm going to be on the road till about the middle of September.
Can't wait to see what the fps are going to be.
