is there anybody who makes a single shot break-actioned .22 LR/WMR/Hornet?

it shouldn't cost much more than 500$

Thompson Center

Savage Model 24.

Edit. Out of production but easily available. .22lr, .22mag, or .22 hornet all over 20 gauge shot gun barrels.

If you shop carefully you might get a Contender Carbine out the door for under $500. The falling block Stevens Favorite has an MSRP in the $300s and a realworld price in $200s. A H&R/NEF Sportster goes for $138? Toward the bottom of the barrel is the Rossi which comes with a spare 20 ga tube for all of $135 (but they're rougher than a cob and ugly to boot).

The H&R "can" be very accurate.

Had an H&R in the hornet it wouldn't shoot anything under 55grains worth a damn but any thing 55grains and up shot quite well. I traded it off to a buddy he is quite happy with it loading 13grains of l'il gun with 55grain Hornady sp
