    Heavy .40 S&W load data...

    My Glock 22 really likes the 200g wfngc from Doubletap and makes for a nice backpacking carry. I would like to replicate this load but searching has turned up no data for 200g bullets above 1000 fps. Anyone know of any published reloading information for hot and heavy .40 loads?


    Caliber : .40 S&W

    Bullet : 200gr. Wide Flat Nose Gas Checked

    Ballistics : 200gr. @ 1050fps / 490 ft/lbs- Glock 23 (4.0"bbl)
    Glock 22 4.5" bbl - 1106fps
    Glock 27 3.5" bbl - 1009fps

    Sounds risky. Try a 10mm would be my suggestion. Are you using the stock barrel? New brass.

    May indeed go for a G20 at some point...but the thinner G22 fits my hand much better. At this point not reloading these. Only shooting the Doubletap. Gas checked...no fouling. The G22 loves em. As close to 10mm as the .40 can be. Yea...no margin for error reloading the 200g. Been reloading 165g and 180g for years. Probably just buy the Doubletaps to carry.

    Underwood 200 grain -- 950fps 401ft. lbs. -- listed as "subsonic ammo"

    No idea on reloads.

    Hornady lists 200 gr XTP and HAP IMR 800X 6.6 gr @ 950 fps. That is the highest I have seen in my 4 manuals. BB, underwood and double tap buy specialized powder mixes to achieve high velocities at acceptable pressures. It is hard to replicate without those powder mixes and your own lab.

    Also a note, unless you chrono the DP and Underwood ammo I wouldn't go by their published velocities. I've some ssen several tests that show DPs velocities to be 150 or more fps slower than what they publish.

    Hodgdon lists one using 6 grains of their longshot powder that puts it at 954 fps but that is almost 100 fps slower than the DT. Like someone said in another post they are using blended powder to reach that velocity and still stay in proper pressure specs.

    I think Glockman10mm loads a lot of .40. Maybe he might have some idea that can get to that velocity.

    I got nothing against 180g XTP's. Good bullets. That's a smokin load. Around 900 fps is the best I could find in my manuals. Thanks for the info.

    Yea...I found this load on the website. I can about guarantee there is no N105 powder in my area. Heck...there's hardly any powder on the shelves.

    I've got a lot of heavy reloading data for the .40, including 200gr WFNGC bullets.

    800x seems to do best with 200gr in the .40 S&W and quite frankly, there's no need for a 10mm when you load the .40 warm. Maybe that sounds like sacrilege to some, but hey the 10mm's popular because people load it way over the norm too, and comparatively isn't that much faster than the .40 (~100 fps) when BOTH are loaded hot and are shot from similar length barrels.

    Using a Beartooth 200gr WFNGC and 800x, 8.0gr of it gives 1,150 fps from my 4" G23 and can exceed 1275 fps from a longer 6" bbl. Several other powders work okay with the 200gr and can give close to 1100 fps in a 4" .40 S&W, VV 3N38 does well maybe a few others. That bullet, which is pretty much the same one as DT uses, is very short for a 200gr, it's shorter than many 180gr JHP's which allows more room for powder. (which is why DT's 200gr velocity wise is essentially identical to their 180gr jacketed).

    If you go over to GlockTalk in the .40 S&W club I have a post called heavy .40's with a good amount of load data in there in pretty much all bullet weights.

    Call me overcautious, but I never warmed up to the idea of loading hot rounds for the 40 S&W. The round is high pressure and I just don't see why I should push the envelope to squeeze a few more FPS out of it with my reloads. My view: load for range use and buy for your 200 gr. for SD or backpacking carry.

    In the FWIW department Hornady shows the best velocity with 200 jacketed from 800x.

    No one suggested hot loading anything. They're just talking the top of the published charts. Truth be known, I have never found maximum published loads to be unsafe. I'd recommend weighing each charge individually when doing so, but as long as you're meticulous it isn't an invitation to an injury IMO.

    I have done extensive and dangerous over pressure testing in my younger days when I thought "magnum" was a word that meant invitation to break limits and push boundaries. There is no denying just how stupid I was, or that by the grace of God all that happened to me was bulged and jammed cases instead of missing fingers or a hand. I generally don't even load near the maximums anymore, and if I do it's out of a full frame revolver or a rifle with a block or strong action than I know can handle way more pressure than I'm going to generate. I also check and confirm the headspace of each of those firearms and make certain I don't get any added pressure that could make a difference when you're at the top of the chart.

    Just be careful and conservative (i.e. follow the tables) with your recipes and there is no danger that there wouldn't be with factory ammo.
