I have a five seven. It feels like shooting a 22 mag.
Because, it basically is a .22Mag. about 200fps or so faster.
So the stats for some Amercian eagle 5.7 40 grain ammo is 1655 fps with 243 ft. pounds ME.
Ballistics by the Inch shows .22 Mag loads from a 5" barrel giving 1474s fps with a 40gr and 1672 and 1723fps for a couple of 30gr loads.
I couldn't find any short barrel data for the .22 Hornet, but from a 10" barrel it moves a 40gr at 2400fps. Now, think about that...the Hornet, from a 5" barrel would still be moving pretty quick, probably a bit faster than the 5.7mm, certainly no slower.
Who recommends the .22 Hornet for self defense???
(waits while listening to the crickets chirp......)
NO ONE.
The 11 folks who took CBM hits from a 5.7 , at the Fort Hood
Massacre might have something to say about
the effectiveness of the round. Oh, wait, no, er, THEY ALL DIED.
While the victims did die, as an argument for the effectiveness of the 5.7 round, this is BS.
Ask any of the uncountable thousands of people who have been shot with a .22 rimfire, and died, about the "effectiveness" of those rounds.
Given the choice, I always opt for the broadsword, over the icepick.
