MODS should feel free to move this to a more appropriate category, if one exists.

Does anyone have experience with Hodgdon Longshot powder in 9x19mm? It certainly seems to give top velocities in 124/125gr. bullet weights, as well as the heavier projectiles. Never having used it, I'm in the dark about its characteristics, and I've always regarded it as something of a Magnum pistol powder, not especially suited to smaller-capacity rounds. CHIME IN, please.

Yes, this same post HAS been posted on other forums. I am looking about for as many opinions as can be had.

God bless Jeff Cooper

No experience with it in the 9 x 19 mm, however I did use it in my .45 ACP, 230 gr HP loads. Let's just say that it did do the job well, but was fairly snappy in recoil vs. Unique or VV N340. If you would like, I could give you a QL snapshot if you give me the barrel length, bullet make and weight (if it is in the data inventory), and proposed OAL.

Thanks, HockeyNick39! My main interest is in using it with 147gr. projectiles, and I anticipate that all or most of them would be cast. My barrel length is 3.75" (I know, not optimal for highest velocities), and I would most likely use once-fired Winchester commercial cases. ANY cast 147gr. cast projectile would probably get close enough for what I am seeking.

God bless Jeff Cooper

VERY edifying, Nick! I do TRULY appreciate the efforts you made on my behalf! Please inform me, if there's some way in which I might reciprocate, in the near future.
