22250.....Reloaded down yes but factory ammo um just two much for the little fox.
The 22 WMR....Yes......used it a lot over snow when no light was required...Bulb Squeaker, full white camo and a bulb squeaker...
17 Rem.......Not only good for fox but coyotes too... Prefer the 25 grainers. Same for the 17 fireball..... Don't own a 17 fireball since I have a 17 Rem. Just recently I compared the ammo....Never realized the 17 fireball was so much smaller then the 17 Rem. Probably if I ever get a custom Encore barrel made..Would like a 20 inch barrel, standard contour, in the 17 Fireball. Kind of a carbine type light rifle instead of the bull barrel I have for the Encore.
22 Hornet.....Yes great fox gun...... use 45 grain SP.
222 Rem and the 223......Use to think they were a bit to heavy....However I can't wait to try out the 50 Grain Silver Tip bullets that Gerald Stewart recommended as good fur bullets.....They are made by Combined Tec...AKA WIN/Nosler....You can buy them as factory bullets from Win
Then there is the 17 HMR. I don't own one since I have the 17 CF.......However I know of a few people that have now taken fox at 100 yards......I think I wuould use these like I would use the 22 WMR.. Only when twilight conditons prevailed at night over snow....Death runs when it's dark....Hard to find once they take off...
What kind of calibers do you like for fox?
