could a 10mm push 135grs @ 2000fps?

    Not that I plan on trying it, just wondering :what:

    What would be needed to drive a 135gr Nosler up to 2000fps, more importantly, what would be needed so you could do it more than once :p

    for fun, lets say were working with a G20, LWD 6.6" barrel, 24lb recoil spring, and some trimmed down 10mm Magnum brass
    (MIL spec. safety glasses and a face shield, too)

    More gun and more powder capacity. Dustin Linebaugh's heavy duty .38-40 Ruger Bisley with a custom oversized six shot cylinder pushes 180's@1800fps and 200's@1600fps. It could surely propel a 135gr at 2000fps. You could also do it in a late vintage Winchester 1892 .38-40 but what would be the point? I push them at 1600fps out of a Uberti 1873 Deluxe Sporting Rifle and they practically vaporize on contact.

    I would suspect that a jacketed bullet would tear itself apart in flight if you were able to fire it at that velocity. Pistol bullets were never designed to be fired at that velocity. It's also possible that your pistol would "let go" at the pressure required to drive that bullet at a velocity of 2000 fps.

    There's no SAAMI standard for 10mm 135 gr bullet? Most it's showing is 1410 fps for 155 jacketed HP bullet.

    Here's the SAAMI standard pdf link (see page 15) - http://www.saami.org/specifications_and_information/publications/download/205.pdf

    2000 fps? Page 16 of SAAMI pdf shows 1950 fps for 357 Rem Max with 158 gr SJHP, so I guess no worry about jacketed bullet disintegrating?

    Don't know what the bullet would do at 2000fps. I can tell you that they are extremely accurate out of that Uberti at 1600fps. Clustering into 1"@50yds. Great varmint load.

    A few years ago one of the Handloader.com's members pursued this very question. The powder he used was 700X.

    One of the moderators over there was able to guesstimate pressures for the loads. Some of us other posters who were familiar with the 10mm were following this closely, checking pressures, etc.

    We finally reached the conclusion that one of the pressure peaks likely was over 60,000 psi. That was with a 135-gr. bullet running about 1700+ fps. So, I wouldn't recomment stretching for 2000, based on what my own Glock had looked like when I blew it up.

    Why would you want to? Such a load woulf fragment the bullet and severely limit the penetration. On top of that, it would beat the crap out of your gun.

    He doesn't want to. He's just wondering.

    Like sometimes I wonder what it would be like to swim in peanut butter.

    Same idea.

    Well I'm wondering why anyone would want to. Like why would anyone wanna know what it is like swimming in peanut butter.

    He doesn't want to, he's just day dreaming.

    Like that daydream you told me about, where you were eating your pillow.

    I never told you about that dream?

    Anyways, driving a 135gr bullet out of a 10mm at 2000 FPS will KB a Glock for sure.

    How about a 145 grain bullet at 1600 fps with standard pressure? Doable using Power Pistol and cast bullets. Might can go a *little* faster using a compressed charge of a little slower powder (like 800X)

    You might can get that 135 Nosler to 1700fps. No way to get it to 2000 without a longer barrel or a lot higher pressure.

    If there was a bullet with appropriate construction to survive a 1500 FPS+ impact then the project would be worthwhile. As it is, most pistol bullets are designed for 1200 FPS and 35000 PSI. Unless you plan on exploding rabbits, why even go there?

    That's the main reason I mentioned using a cast bullet instead of jacketed (also less barrel friction, but that's usually not an issue with pistol-length barrels)

    I've thought about seeing how fast I could cook a 135 out of my 6.5" 610, but I was thinking more like 1700-1800. Just because, I guess. :)

    From Shmackey's link -http://www.doubletapammo.com/php/catalog/product_info.php?cPath=21_24&products_id=46
    But this with a 95 gr bullet and not 135 gr. :D

    Even with 125 gr bullet, it only produces 1700 fps (funny, "only" 1700 fps! :D) - http://www.doubletapammo.com/php/catalog/product_info.php?cPath=21_24&products_id=98

    Like I said, excellent varmint load.

    A 454 Casull can launch 180gr JHP even faster.
