I had access to a large quantity of Super Vel in about 1976. It was old stock that a FFL dealer friend had acquired a few years before. I shot quite a bit of it back when my Smith & Wesson Model 10 Heavy Barrel was the only handgun I had.

Chronograph tested some from this batch of Super Vel in July of 1980. I ultimately shot it all away except for a single box.

In 2010 I discovered a couple more boxes of the Super Vel I had stored away and hidden from myself. I undertook to retest the ammunition in the same revolvers I had used in 1980. I also tested it in other barrel lengths.

It was scalding hot summer time on both occasions so temperature was approximately the same. I recall that in both instances it was hot, but this is Texas in summer.

Here's the July of 1980 tests.

Here are the June of 2010 tests using the same two revolvers used in 1980.

ME 349 ft./lbs.

Model 14 8 3/8-inch

Here are some additional tests conducted in 2010 using two additional barrel lengths.
