    For whatever reason, I’ve only shot 180 grain in this caliber. I guess because the first time I bought some ammo, 180 was available or cheaper or recommended. I really don’t remember.

    Local gun store had some 165 in stock so I bought a couple of boxes of Blazer Brass. They had a few more boxes of WWB in 165 as well. So, I bought the Blazer on a whim just to see if it’s any different from the 180 grain. Most of what I’ve shot is Magtech 180 and S&B 180 FMJ target rounds. And WWB 180 grain JHP’s.

    I’m guessing with the Blazer 165, I really won’t see any noticeable difference. Shooting a Glock 22 and a Beretta PX4 Storm.

    Anyone think there is a big difference between 165 and 180 for .40?

    I do not believe the velocity changes much until you go down to 155 gr or less.

    My goals are to go subsonic for working with a rifle: Keltec Sub 2000 (Sub 2K) suppressed, so I’m going to reload 200 gr bullets into my cartridges.

    Challenge is getting them to cycle.

    That’s kind of what I expected. I may go back and get a couple boxes of the WWB 165 and compare it to the Blazer 165 along with some 180 grain S&B I have saved up at home.

    The 15 grain difference between 165 and 180 equals 0.03 ounces - the exact weight of a postage stamp. I don't think that will affect terminal performance.

    My JHP ammo for my home defense in my G22 is 180 grain and isn’t likely to change. However, since I can find .40 locally, I prefer to shoot it now rather than dive into my stash of 9mm. I go through the 9mm faster because I use it for range and games and I’d prefer to save it since all the competitions have been cancelled due to Covid-19. When they start up again, I’d like to have a good supply of 9mm ready. So, I plan to shoot .40 in the mean time. I was mainly curious as to whether or not the 165 was snappier versus the 180 or whether one was considered more accurate.

    I found it to have a little more muzzle blast and recoil and 180. But I never shot them side by side, and they were different brands, so could just be subjective.

    15 grains is lots more than a stamp. The 165 grainers are loaded hotter with more blast, energy and recoil. Makes a .40 a .40 in my opinion.

    I’ve got some 165 and180 HSTs. I‘ve shot a mag with both and I can’t really tell which is which.

    Actually it IS about 15 grains. The man was right.

    180 is the most readily weight available in range and HP. One of the reasons I like .40 over nine is this. In 9mm the common range ammo is 115 but the best self defense is 124 and 147. I like that the range ammo is easy to find an equal weight in HP. I shot some 165 Golddots and it seemed a bit more push than 180.

    I get issued 180 grain HST. I purchase 165 grain on my own. Corbon 135 grain is a good approximation of .357 Magnum 125 grain SJHP.

    I generally carry 180gr and that's what we were issued. In unofficial testing, putting down deer, I've found the 165gr seemed to be more effective, but there are always too many variables to really matter.

    I shoot both 165 and 180 grain weights in .40. For range ammo FMJ, hands down 180 gr gives the most group consistency both in my Glocks and M&Ps.

    For self defense hollow points, I prefer Remington Golden Saber 165 grains in my Glocks. In My M&Ps prefer Federal HST 180 grain. By "prefer" I mean what provides the most group consistency as well as having a good combination of penetration and expansion numbers.

    I am fine running 180gr in a full size gun but like 165gr in my g27. Insurance for good bullet performance n shorter bbls.

    I currently have 180gr. Winchester Ranger T-series as my EDC load for my Glock 22, but I prefer the 165gr. loading. I believe that the Glock 22 with the 165gr. loading is the best power-to-size ratio of any self-defense pistol currently out there. Just my opinion. It's hard to beat .40 S&W at 1,160 fps.

    Timely thread as I have some 180 gr. Blue Bullets on the way, have been loading 165.

    For many years I carried 165 HPs. I practiced with mostly 180s. I began to notice a substantial difference at the range. "Carry" 165s seemed hotter, with more felt recoil than the same in 180s. I bought some 180 HSTs. Heaven.

    I still have a couple hundred rounds of Gold Dot 165s. They serve as a back up now.
