Need some help with a 165gr GD load

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.

The parts in bold are my sentiments too. I used the identical data that you listed in the earlier post. my results were about 50 fps faster accross the board. There has been some variability with A9 it seems, plus different barrels will react slightly differently too (my gun seems to agree with A9). So the differences don't seem too out of the ordinary. I imagine if you tested your loads at summer temps that velocities would bump some too.

15.2 grains under a 165 was my carry load for a while before I decided to go with factory for in-town SD (not getting into that discussion here). I thoroughly tested that load for function, including running it in IDPA. I also shot it at different things that I could drag to the range. It is a load with reasonable recoil, good groups, and reliable function in my G20. 1335 fps is a pretty good speed for that bullet in my opinion.

Hopefully this helps. All the numbers are in the video's description.

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!
