    I took my new Glock 35Gen4 to the range today. I vowed to never buy a .40 again; that didn't last long.

    The Underwood 135 Grain .40 ran like a champ. The 50 round box ran flawlessly. The primers looked good and the brass looked normal. The round was hot for sure, I wish I had a chrono. I also ran some Lawmen 165 grain FMJ and Blazer 180 grain. The glock 35 ate them all but I gotta say the Underwood stuff was FUN!!!

    Probably 1550-1600 fps. Insane.

    I don't know. 1550-1600 would be more like the 10mm load. Though he is rating the 40 load for 1500. Makes me think he's holding back on the 10mm load.:)

    Well there is a comment on the product's web page where someone said they chrono'ed it from a G23 at around 1525-50 so the G35 should be even higher.

    That has got to be hard on the gun, regardless of make.

    Wow. Now I think we're being jipped even more on the Underwood 10mm 135gr load than I started out. That is a pretty amazing load in 40!

    Someone please PM me if any mention of it being tested for pressure with real numbers so it is known as safe. Otherwise I'm not going to bother with the inevitable arguments again.

    You could email Underwood and see what he says. Matter of fact I'ld be curious to know too.

    Yeah, I got rid of my .40 awhile ago. I missed having a .40 so I went and got a Gen4 22. I still prefer a .45, but I like the .40 to.

    I wonder how effective that round would be as a SD round. Sounds like it wouldn't be a very deep wound but would be quite nasty. I shot that same bullet loaded by DT in the 10mm into waterjugs. Found the core in the third jug but the first jug was almost ripped in two and the second was also torn apart really bad with several holes from the shrapnel. Seeing a test into a block of meat they leave some nasty holes.

    As a reloaded and an owner of a Gen2 G20 10mm, a Gen3 G23 and G35 I find the +1,500ft/sec out of a G23 totally unbelievable.

    It's hard enough to get them to 1,600ft/sec in a stock lenght G20 barrel much less the shorter G23 barrel.

    I friend of mine has several G24's and has tried repeatedly get the 135's to 1600ft/sec and had failed every time.

    I know for a fact that DT ammo doesn't reach it's advertised velocity out of a stock lenght G20 barrel. Barely reaches it out of the 6" hunting barrel.

    Even with 11.5 gr max load of longshot you only get 1434 fps and 31,900 PSI out of a 40 sw test barrel. There is no way you are going to get that velocity out of a G23 without blowing it up. You certainly are not going to buy over the counter ammo with over 32 K psi sami max pressure.

    I've used 800x and 135gr Nosler. Average from 4.02" Glock 23: 1550+ fps. It's doable, I've done it. 1700+ from 6" bbl. FWIW IMR shows their 135gr load only at 24K PSI...40 S&W is rated for 35K.

    Too bad 800x kinda sucks to load with. I wish I knew what Underwoods used. VV 3n38 may do 1500+ from G23 (135gr) since it's got me near 1400 with a 155gr.

    First I hear of those velocities in that caliber/weights.

    From the Lapua reloading guide, using 3N37 or N350 will give you 1367 fps max at their max loading with the 135 gr. nosler bullet, using a 5.5" barrel, sure to be much less out of a G23.

    3N38 burns slower than 3N37 or N350 so out of the smaller barrels its a non starter.

    I am a non believer for anything over 1400 fps with 135 grain bullets in .40 cal and G23.

    Have these Underwood numbers been verified? I have DT ammo in 135 grain which runs 1375 fps. It certainly makes the G27 snappy! One thing about DT is they load the Nosler bullet which is not my favorite.

    Funny you mention that. I have some DT 357Sig. No trouble with the velocity (1452fps average but with a 154fps ES). However, they advertise that they load 125gr Sierras but they sure look like Noslers.
