Rich,
Not to speak for DocGKR, but I know he's a busy guy, so I thought I'd pass along his data on the 124 Gold Dot (saved years ago from a site that he's no longer on):
9 mm Speer 124 gr JHP Gold Dot (53618) fired from G17 at ave vel of 1149 f/s; 5 shot ave below:
BG: Pen = 13.0", RD = 0.62", RL = 0.32", RW = 125.5 gr
4LD: Pen = 16.6", RD = 0.51", RL=0.43", RW = 125.2 gr
9 mm Speer 124 gr +P JHP Gold Dot (53617) fired from G17 at ave vel of 1232 f/s; 5 shot ave below:
BG: Pen = 12.0", RD = 0.67", RL = 0.30", RW = 124.2 gr
4LD: Pen = 13.0", RD = 0.54", RL= 0.39", RW = 124.5 gr
Both the 124 GD and 124 GD+P are acceptable, the +P is just a bit better for LE agencies. I find the 147 gr HST has a very low felt recoil.
Facts matter...Feelings Can Lie
Cool, did not know that GJM. The +p sure "pops" for me.
Good stuff. I am slightly confused by the numbers, though. BG is Ballistic Gel, right? And 4LD is four layers of denim, with Pen being penetration in inches? Forgive me, but it looks like the +p round has less penetration than the standard round. Am I reading that right? That seems kind of...backwards? Bear in mind I'm pretty new to all this...

BG = bare gel (ie. no covering or intermediate barrier). This equals base case performance
4LD = four layer denim test. This demonstrates terminal performance typical in many shooting incidents.
The slower standard pressure GD bullet expanded less, so it penetrated deeper; the +P GD had a higher velocity, expanded larger, so had more drag and penetrated less--very common result.

No reason to guess, as I've never said I had any training or did any testing.
How do I know the HST bullet didn't penetrate 13.8" because it was a 148.4 gr bullet?
What would the penetration be if it was a true spec 147 gr bullet? 12 inches?
What was the data of the individual 5 rounds?
Anyone wanting to pick up any 147 HST better latch on to the Target Sports deal. $399.80 shipped for a case is the best deal I've seen in years on the stuff.
