thank you for your information on221 fireball
I have a cooper 221 fireball. I have leupold 4.5 by 14 30mm tube 40mm head side focus an a ken Farrell costom mount. I used a 40 gr v max 15.6gr of imr 4227 longest shot 300 yards. I had a hard time making this gun shot.
used all kinds of powers bullets weights. 40 gr v max an imr 4227 is the only
thing that would shoot well. not impressed with cooper rifle. or maybe it is the
caliber that is hard to set up. thank you for your imformation.
