LOL!
(Except he’ll kill his own dog.)
Well I didn’t say it was a perfect solution......:o)
I freepmailed the guy ....told him to scope his marlin and use stingers as that works here in the panhandle of Texas for my coyote solution within a hundred yards. type of bullet and shot placement is key to quiet solution !
If he could keep his pup kenneled up a few weeks the liquid solution is magical. I have also seen pieces of compressed sponges fried up in bacon grease scattered in and about coyote land that does the trick.........think corked up at one end ugly death.
Cheap route was suggested to snag a surplus 6,5x55 Swedish Mauser and a Scope and lay waste to the critters for less than a 150$ if your a careful shopper.
Stay safe !
...and the cat too!
