9mm ammo, 147gr Gold Dot vs HST?

[Chuck Haggard]

In the old Firearms Tactical articles on the subject, the standard pressure 124gr Gold Dot was actually recommended for folks using service sized 9mm pistols.

I'd carry it without losing sleep if I couldn't get my preferred +P, same-same with the 147gr

Just picked up 200 rounds of 124 HST, couldn't find any GD

Both the standard pressure 124 gr GD and HST work fine.

When I've chronographed the 124 grain standard pressure and + P Gold Dot loads out of my G17 a while back, most of it was running at a velocity over factory spec. The standard pressure was right about the factory spec velocity for + P (1220 fps) and the actual + P rounds were going between 1260 and 1310 or so, depending on the specific lot. I carry the + P because I have it, but the standard pressure would be just great too.

The only exception to the above that I personally have run across is some surplus standard pressure 124 gr. Gold Dot that was supposedly rejected from a French National Police contract for being loaded hotter than they wanted. I chrono'd it at the stated factory velocity of 1150 fps for standard pressure. Also great ammo from my use of it. Very accurate.

That's at least partially because you were shooting it out of a 4.5" barrel and the chrono numbers for that stuff are based on a 4.0" barrel. Also, your barrel had polygonal rifling which probably resulted in an (admittedly very slight) increase in velocity over the factory test barrel's likely standard rifling.

Shoot it out of a 4" barrel with conventional rifling and I'll bet you'll get numbers a lot closer to Speer's.

G2 can be expensive, hard to find, and is as yet not well proven in actual use (only 2 OIS I am aware of).

That didn't take long. Any details you can share?

[Chuck Haggard]

Ammo varies from lot to lot. I've crono'd the +P 124gr Gold Dot as high as 1275 average from my 5906s when we were carrying those, and as slow as in the 1220s.

[DocGKR]

Nope. But it did work acceptably in both shootings, although neither were shots to the torso.

No BS question: What defines of an ammo "Lot"?

Were they to the head, then?
