Do you find them to be accurate? I haven't shot mine enough to know much about it and won't be wasting Underwood anymore. 10 is hot but I don't find it intimidating at all. The Rubbermaid Glock seems to soak up recoil pretty good. I kinda like the feel of power.
Iâm not exactly a âbullseyeâ shooter but at 15 yards or less I can normally shoot out the X ring on a B26 target with little trouble, at 20-25 yards the groups definitely start to open up by a substantial amount, but Iâm also âthat guyâ and will attempt to shoot my G19 & G17 out to 100 - 200 yards to see if I can, yes itâs silly, but I enjoy the challenge.
The whole point of the word salad above is to demonstrate that I found shooting hot, jacketed Underwood 10mm ammo was just as accurate as the milder âoff the shelfâ 10mm ammo from 135 grain to 200 grain ammo and smaller calibers, such as .40 S&W & 9mm, donât get me wrong, the Underwood 10mm offerings are âsnappyâ to say the least and youâll have zero questions if itâs loaded to the cartridges safe limits, I was still able to shoot out the X ring on a B26 out to 15 yards, albeit at a much slower rate of fire, I also found that shooting out to 100 yards was easier due to the flatter shooting cartridge, I think I recall only hitting the 100 yard plate once out of 50 rounds with the G22 , 8-10 times with the G17 and at least 12-15 times with the Underwood 180 grain FMJ 10mm ammo.
We did run into horrible accuracy & feeding issues shooting the lead hard cast 180 grain offering, the bullet basically tumbled out of the muzzle, but then again we knew that shooting un coated lead projectiles out of a factory Glock barrel wasnât exactly all that bright, the owner of the G40 told me he picked up a quality aftermarket barrel with standard rifling and the hard cast shot extremely well.
Hickok45 made a video shooting hard cast 10mm out of a G20 and he had a similar issue, once he switched to a LoneWolf 10mm barrel the hard cast also shot fine for him.
I found the video showing the hard cast lead bullet issues, I believe he also has a video up of him shooting jacketed Underwood 10mm ammo with great results.
