Hi Mate, Had a .22K hornet for about 3 years and IMO an excellent calibre :thumbs:and would great for use with regards to comments in your post.
i reload mine with 40 Gn Sierra blitzking head & 13 Gns Lilgun Powder this combination will drop a fox at 175 yds ( up to 200yds if confident ) Easy and cheap to reload, quiet with a good mod, no recoil worth mentioning, 700 to 800 Ft Lbs energy more than enough for fox.. I also use a .223 but looking back and taking into account that average range of foxes shot is under 150Yds, i have accounted for many more fox with the hornet than the .223.
