F**k China!
62 GDSP 24445SP, 16" 1/8, unsuppressed, my data
5-shot group, magnetospeed IIRC, avg 2660, SD 49
12-shot group, oehler something or other, avg 2649, SD 31
I know I have one from a labradar but can't find. It was about the same. About the same from other barrels, too.

Molon, I think, found Gold Dot to be between Fusion and MSR in velocity. (Edit, here: https://www.ar15.com/forums/ar-15/Fe...Dot/16-687846/ ) Or perhaps my memory fails me. My 16” data shows MSR to match your Gold Dot data, but the barrel I used was quite slow; matched by a 12.3” with other cartridges. I can’t find any chrono data I’ve collected from SBR’s, though I thought I did.
I wonder if Gold Dot has changed to mimic the MSR. That might make sense.
Edit: this dude on TOS (Eagle_19er) found a big difference in 64gr Gold Dot and MSR in 4 barrel lengths. https://www.ar15.com/media/mediafile...SxS-233178.JPG Maybe my info is simply outdated and precedes the 62gr Gold Dot load.

I remember the 64 GD being faster and sloppier, can't quantify, but the 62 has been quite an improvement.
There's a thread here somewhere in which we kicked the GD/Fusion/MSR thing around. I couldn't find it in a quick look, someone else may be able to.
We also did the same thing with some of the Federal TRU and classic loads, too.

That was Molon’s thread. He posted the same OP on TOS, which is what I linked, because the pictures that contained the velocity tables were still present there, but the ones here have been lost to time. Here’s the M4C one: https://www.m4carbine.net/showthread...Grain-Gold-Dot
Yes you aim high because the angle of the glass will turn the bullet down.
That said auto glass does some funky stuff and it’s really unpredictable. The key to shooting auto glass it dumping a ton of rounds in the same place. You eventually shoot a hole to shoot through.
Edit: an important caveat to shooting auto glass and holds. You hold high shooting into the car. For the same reason, you hold low shooting out, as the glass will now turn the bullet up.
