Effictive range of a .17hmr or fireball? Thats a FAST moving caliber, that can travel a long distance in a short amount of time … but on the flip side being so fast will hurt you as you get out there.
You should be fine for a couple hundred yards on a fox/yote … as long as your a good shot but not with a hmr …
I would rather have more caliber for coyotes … but a .17 will do that part … as long as you do yours
I use a camo nikon buckmasters 3-9 on my .223 for predators … I used to use exclusivly leupold optics … than over the last few years I have only been buying/using Nikon (Spotting scopes, binos, rangefinders, scopes etc.) and have never had one let me down.
The 250 yard Primos (optroninics) scope light is a nice unit for the money … but for somereason mine had something come loose.
