Rifleman2,
Noticed you indicated you often shoot 300 yds, I doubt you would need cmo when shooting out past 200 yards. Coyotes (if that's what you're hunting)seem to be pretty curious and aren't going to immediately scamper away. And as far as camo is concerned, if you're a spot and stalk guy, the rifle's always behind you (slung) and out of sight.
I used to be very concerned with camoing and tried all the tricks. Now, as long as I am in all white or drab colors, I'm not much concerned with what the rifle looks like. And when I'm down to shoot, all the animal is going to see is two small black spots in the distance (objective lens and tiny muzzle). In the event you might question, "What does this guy know, anyway?", might add over 42 years I've taken just over 2600 coyotes here in Western Montana (good record keeping). Probably 200 of them calling and the rest spot and stalk. Mike
