Back around 1970, roughly the same time Super Vel was making a fuss, a guy in one of the gun magazines, I think it was Dean Grinnell published what he called a hot 9mm load.

I will not repeat it here but it was 2 grains above what the Speer manual listed as maximum for Unique in the 9mm. I figured he would not have published it if it was not safe so I loaded maybe 20 rounds.

I loaded up a mag for the Browning Hi-power and let loose. It threw the empties around 30 feet and the primers were as flat as a frying pan. Some of the primers just fell out. The load was insane and it probably would have blown up some guns.

I still have no idea what the consequences of him publishing that load were. It must have resulted in some damaged guns.

When I was active duty USAF we were issued the M15 SW Combat Masterpiece .... beautiful solid revolver. I was EOD an we weren’t as “supervised” as SP’s, Aircrew etc.... and got away with purchasing our own Super Vel 110gr JHP... Had we been caught carrying that ammo versus the old M83 ball issued we’d have been still making little rocks out of big rocks at Levenworth.... But we never felt under gunned while burdened with the M-15. Later mid career we wormed our way with command to use 1911A1’s and keep the 1911’s when new M9 berettas were issued.

Loved those Super Vels while we had the Smiths.....

The later [post-1968] Browning GPs with the pivoting rather than internal [like a M1911] extractor were notorious about cracking slides with overly hot loads. British 9mm ball ammo, loaded hot for the L2A3 Sterling SMG, will also do it. And, sometimes, the two-piece FN High Power barrels will come apart.
