    Bullet expansion velocity tables

    Is there a definitive list of minimum (and maximum to a lesser degree) expansion velocities for bullets somewhere?

    Most rifle bullets have them for reloaders. But handgun bullets are hit and miss.

    I can dig deeper into Google, but I'd like manufacturer's published data rather than some dude on YouTube.

    And God came down and gave unto John Moses Browning the divine knowledge of the perfect handgun. Amen.

    My older Sierra Handgun manual had the velocity windows for HP's listed, but most makers seem to have skipped that essential feature. They seem to have the philosophy of "just trust us, they'll expand".

    Yeah. I'm not so much in to "just trust us" *wink* *wink*. Especially out of my compact .45s.

    I'm running Gold Dot 230gr out of my 4-4.25" 1911's. Out of my 5", Gold Dots and some solid copper 185gr at +P velocities. The Gold Dots did require a bit of tweeking to get them to run 100% out of one of my guns; but now all 5 1911's eat them up happily.

    Seems to me the best combo for short barrels is pure lead that is coated to drive at higher velocity. I remember the Nyclad bullet was getting a good reputation in .38's but the 9mm auto craze took over soon after and Nyclad seems to have faded away.

    The 135 grain Gold Dots do an amazing job. I had been stoking my 38 specs with the BB 158 grain + P loads. But, with my new 642, the brass sticks in the chambers. Bad for obvious reasons. I asked S&W a "theoretical" question about their cylinder being out of spec and they said BB was close to proof pressure for the gun and waaaay above SAAMI. And they would be able to tell if I sent the gun in.

    I've been also looking for something from my 3" 45 and my wife's 3" 40. Federal says "our HST will expand very well from your short barrel" when I ask but provides no data or proof. The closest I've found is This Lucky Gunner Study which uses a 3.6" barrel 45 and a 3.4" barrel 40 for their testing.

    I'm OK with the 180 grain HST (factory) and Gold Dot (what I use for my reloads) used in my wife's 40 given the penetration and expansion in the LG test. However, I'm not a big fan of the 230 grain HST (factory) results or the Speer 230 grain Gold Dot (reloads) out of the 45. Plus the 230 grain 45 Gold Dots are unicorns right now. And I don't want to use +P 45 ammo in a subcompact. So I'm going to work up a Hornady XTP load for it over at the workbench.
