I have two boxes of American Eagle 38 Special + P that I bought at least 15 years ago. It is marked AE 38H and is 158 grain Semi-Wadcutter.
I can find no data on this particular ammo and I thought it possible that some of you might have an idea of how hot it was loaded or might have some old Federal data.
I would appreciate any info that you might provide. Thanks.

As you know, American Eagle is Federal's economy brand.

I shot some of your load about 10 years ago and remember it made minor power in a 4" 686, but not by all that much over. The non +P did not make minor power. Should be OK in any modern revolver. Don't remember much else about it.

Since it's factory ammo I'm sure it is well within the SAAMI specs of the time. Any factory ammo, baring a mistake that requires a recall, is safe to shoot. I'm betting it's no hotter than the current AE +P ammo on the market today. (sorry I couldn't give you numbers you were looking for)
