I realize that there don't seem to be many gun manufacturers chambering the "Triple Deuce" (.222) these days but I still feel it is one of the most accurate and fur friendly calibers out there today. It is easy to reload and very cheap to shoot as well. It handles coyotes out to 250 yards. Not near the muzzle blast of a 22-250 either. Just food for thought Gents!
Now if your looking for that "Dynamic Dual" caliber for hunting both whitetail deer or varmint/predators, you can't beat the .243 Winchester or 25/06 caliber in my humble opinion.
