I have seen very high variations in the 60 grain loads, and the slower twist barrel 1 in 16 only marginally stabilizes them.
I have heard the 60 grain load, or equivalent, was used in black ops south of the border...
The 60 gr load is also used by the IDF to plink “protestors” (with molotovs, walkie-talkies, etc) in a “mostly less than lethal” way, such as at the femur.
PS: I have not tried the 60 gr Aguila SSS from my Taurus 22, but thanks for the reminder. I will do it soon.
It functions perfectly thru my Ruger Standard Model with a 6” barrel, but the slugs keyhole. They randomly hit the paper sideways at 15 yards more or less. Which may or may not be a plus for a defensive 22.
Pretty nasty wound channel I’d guess, because that 60 gr slug is long. Be an interesting test in ballistic gel. See how many hit at what angle at what range out of a pistol, and what they do.
