40 S&W which bullet weight? Powder?

Tested AA#5, Unique, Power Pistol, and Win Super Field WSF with 165 grain bullets. The Win Super Field performed the best with uniform velocity increases with increased powder charges. The most noticeable thing was that it had a softer recoil at the same velocity as the other powders. Power Pistol works great with 155 gr. Hornady XTP's. I'd rate the 4 powders with 155 and 165 gr. bullets with WSF 1st then Unique and Power Pistol a close second.
 
I run 180 MG FMJ bullets, 7.5 grains of Longshot. Just ordered some 155 FMJ's from Montana Gold for other shooting disciplines and will also use Loudshot with them since I have a keg of it.
 
You mentioned that you have titegroup and universal. I've loaded thousands of rounds with both those powders. The bullet I used was MBC IDP 7 140gr lead truncated. 5.0 gr of titegroup or 5.4 gr of Universal. Snappy because of the light bullet but very accurate. I've also loaded 4.4gr of universal behind a 180gr lead truncated. All of these were shot out of my glock 22 or 23.

There are a few heavy bullet/fast powder recommendations on this thread! Proceed with caution if reloading for a Glock no matter what generation
Proceed with caution with any round for any gun! What you shoot in your M&P or Sig can be shot in your Glock! Makes no difference, glocks are great guns.
 
All of these (ed. lead bullets) were shot out of my glock 22 or 23.

This doesn't explicitly say the barrels are stock, but I am not following any advice to shoot lead in my G22 or Kahrs with stock polygonal rifling barrels, and I am not replacing the barrel of the Glock at $200 installed. The Lone Wolf barrel was ruled out by my gunsmith in favor of KKM, with which he has found better results.

Fortunately, I have well over a thousand left from a Zero FMJ-TC buy 3-4 years ago at what now seems like a good price. $200+, more like $300 installed for a special barrel, will buy a lot of FMJ. I don't use it to compete, so YMMV relative to volume.

Of course, if someone wants to share solid information about why lead bullet restrictions are silly in polygonal barrels, I'm interested.

The KKM barrel for my glock dropped right in. It required no modifications. It functions flawlessly and is as accurate as any stock barrel.
 
I have not experimented with a lot of powders in 40 due to having such great results with power pistol. With 155gr XTP's and 135gr gold dots I had extreme spreads of only 20 fps on 5 shot strings. Not to mention the 155's were at 1300fps and the 135's were at at 1400 fps out of my glock 35.
 
"what bullet weight and powder everyone likes? The why...."

Many like 180 grain bullets in the 40S&W.

I feel that the range is going to be short if used for anything other than paper and a little added velocity to expand is nice. So, I load 155 gr Hornady XTP JHPs. I've used Unique and Tightgroup but favor 231/HP38.
I also load 155 gr lead to the same/very close velocity using 231/HP38.

The whys are not as easy. The lead load to the same velocities as the jacketed is because I'm cheap and get a close recoil, bullet drop and follow up practice (I shoot double or triple tap). I run these in an XD SubCompact with 3 inch barrel, so greater velocities are not in the cards (yes, I can push them but not in my comfort zone). This nullifies my 'greater' velocity excuse over the 180 grain pills. So the why has to come down to, because I want to.
If the little thing wasn't so small and didn't feel/shoot so well... I like my 1911A1s... But....

Tribulations.
 
Thanks all. Now for my next question. What is the most common weight for .40? What weight is most common in plinking rounds found on shelves?
 
Just shot my g23 reloads for the 1st time yesterday with universal clays.

I used the 180 grain fmj and am very pleased with the results
 
Btw, I'm using a storm lake aftermarket barrel as I don't trust the factory oversized chamber. I'm not gonna reload glocked 40 cal cases over and over. That's another topic though
 
Most common I see is what is sold in factory ammo and the is 180gr FP for the .40 s&w, so that is what I load. I only use HS-6 for my loads and I use 6.3/6.4grs, this gives me a nice target load for the range. I also have found it to burn cleaner, I did try titegroup but didn't like that, fast burning powder. Tried a few with hp-38 and that was good but just liked the hs-6 better.
