Swivel Machine also produces an air powered arrow launcher and claims 600 fps. They also market barrels for Ruger rimfires that use blanks to get up to 435 fps. Neither come close to the 300 foot pound mark though. I have one of the 10/22 barrels but have never used it.
I’m not sure of the date, but I believe it was back in the mid 1970’s a company offered a more militarized air powered arrow gun to the US military for covert use.
The idea was as a means to quietly take out sentries without having to get too close.
For whatever reason, I don’t believe that the military bought it, so they went commercial.
Swivel Machine Works Ink. (swivelmachine.com) offers arrow shooting rifles using both high pressure air and industrial blanks,
Their top of the line offering is the Airrow Stealth capable of exceeding 500 FPS with light weight arrows.
Airrow Stealth
I was interested in one until I saw the $1,600.00 price tag.
However, they do offer a modification for the Ruger 10-22 rifle.
I bought a full kit, Barrel, arrows, and pack of high powered industrial blanks for less than $500.00.

It is marked for Blanks Only.
The aluminum arrows are cut off in back to fit down over the inner barrel
