Ever since this thread started, I've been looking for my range books from the late '60s and I'm darned if I can find them. A lot of things got displaced/moved around during Ike, and my notes from '68-'72 are AWOL.

I thought SuperVel was as close as you could come to a death ray. I bought 9mm and 38/357 when ever I could (that is, when I could find it and had the money to pay for it).

Some of the bullet weights were unusual, like 112gr 9mm and 137gr 357.

In those days, I had 3 9mms, a 39-2, P-35, and a P-38. IIRC, the 39 would run OK with the 90 and 112 grs, but only from down loaded mags. If you tried to feed from a full mag a six oclock jam was certain (as opposed to just likely).

The P-35, mid '60s production, wouldn't cycle more than 3-4 round before producing a 12 oclock jam. And of course, the P-38 was a single shot.

The 38 and 357 were not match ammo, but out of my 2" Combat Masterpiece I seem to remember groups around 3-4" from sandbags @ 25yds. I think the 357 did about the same from a Highway Patrolman.

SuperVel was assumed to be very high velocity ammunition and there is no doubt in my mind that it was faster than anything else at the time. But no one had a chrono, so all we had to go by was what we saw in the gun rags, and very few of the gun writers of the day had any more hard information than the rest of us.
