    I'm getting ready to load some 165 Speer GD. I'd like a warm self defense load. My first hand gun was a .44mag so I'm not afraid of recoil. My issue is that I do t want to over run the bullet. I'm looking for some good expansion and hit and I'm ok with a little loss in Penetration. But I don't want over expand it and blow the pedals off causing over penetration. I'm thinking of around 1300fps. I've got some power pistol, auto comp, A#9 and long shot. I'll have to do some testing and see which powder gives the least flash and report. Any recommendations or advice on the load I would Appreciate.

    Stock G20
    50F, 95% Humidity, 902 ft elevation
    165 gr Gold Dot Hollow point
    AA #9
    Starline brass
    1.255 OAL
    CCI 350

    15.0 = 1268 fps avg
    1242, 1297, 1266, 1274, 1261

    15.2 = 1286 fps avg
    1308, 1267, 1291, 1280, 1287

    15.4 = 1310 fps avg
    1307, 1309, 1318, 1307

    15.6 = 1311 fps avg
    1322, 1319, 1308, 1297

    All of these were extremely accurate and I didn't see any signs of over pressure in any of the brass, which was brand new.

    Thanks for info. That will save me a lot of work with #9. Do you feel like that's a good Velocity for that bullet?

    I think I could have gone faster, but I didn't try anything (yet) after these loads. The accuracy and grouping of 15.6 load was outstanding, so I ended up loading 200 for a SD load for the home. Underwood pushes his 165 GDHPs at 1400+, so there's definitely room for more speed, but I'm not sure how the GDHP acts at those speeds. 1300ish was great.

    I personally like #9, but there are likely more powerful powders to use at 165 gr. But for me, it burns clean, low flash, no worries on overpressure and is very accurate.

    I think your right about the A#9. I use Longshot in my hot 200gr BT HC because I was looking for a real hot woods defense load. The #9 I tried at the time just wasn't getting me the vel the book said I should be getting. (In my stock 20sf) Speer loads these 165's at 1150fps from a 4" barrel so I'm sure they Engineered the bullet for at least 1200fps from a full size gun. I've seen some utube vids of 165's at 1300 that look real good in the gel. Like I said before I'm not looking for a max load, just something hotter than a .40 but still works good.

    I load up and shoot GD's in my 9mm's. I havent found anything to date better than XTP's for the 10mm and .357's. They are not bonded, But over all they only shed around 5% of there lead over all. And you can drive them to hell and back.

    Blue Dot is my 10mm powder of choice. :)

    I did the same thing. Went from 25 yrs of 44 mag to a G20. Stock pistol. Upon advise here on the forum (tater) I tested #9 and concluded that Taters load was the most accurate. However, 15.2 yielded only 1256 fps in my gun. I tried two sessions including moving the chrony out to 12 ft. I think I will try another chrony session to be sure, but the bullets open up fine and ballistics for 1256 are more than adequate. Best of luck!
