I think Harly Quinn clears things up nicely, but I must say I'm still kind of jellous about the fact that he is a "Golden Shellback" I'm just a regular "Shellback" Thank you for ur service Mr. Quinn.

DC3-CVN-72...
Yes it was pretty nice sailing back then...The initiation was very rough, but worth it...
The 38 is what I carried when LEO in a revolver Colt 6" for a few years then the 15-3 S&W... When issue was Beretta 9mm it was a real upgrade, the biggie, being so many rounds in the mag
Take care...

Alliant has published data for the 38 using their 2400 powder (they call it +p but it only lists at 17,400 psi) 158 g LSWC at 1035fps, starting load 7g.
It has always been my understanding, if you start to see problems with the primers, (cratering etc) it really doesn't matter what the published pressures are, your load is too hot.
After everything I have read, sorry Harley, I am of the present understanding that when my .38 Colt was manufactured in 1926, (there was no +p) .38 Special pressure was 21,500 CUP max. (based on old published, that is, pre "+p" handload data)
Example: Top load, 1974 Hodgons: 150 grain JHP, 10.5 g H4227 "small pistol primer" 959 fps 15,500 CUP (6" barrel)
1971 Sierra: Starting load: 150 g JHP, 12.0 grains Hogdon H4227, CCI-500 primer, (no pressure listed) Top load 14.2 g H4227 @ 1100 fps (6' Barrel)
The fastest 150g/158g Sierra loads were all AL-7, most velocity, least muzzle flash etc. Too bad it is no longer available, or maybe it is,,,,maybe AL-7 (or it's equivilent) is Buffalo Bore's "low flash" non-canister powder they use with their "standard pressure" 38 at 1100 fps from my 6" Colt barrel?
I know, CUP and PSI are not directly convertable, but primer deformation is a function of CUP and primer deformation is what I watch for when I think I am on the edge.
