Aw the title says what is the max range the 222 rem can hit something at reasonably consistently. Are you using factory or homeloads? I know you wouldn't shoot a live animal at 500 yards with it but even just paper or steel. I am going to try and push mine to the max range for some targets.
I have a RCBS FL Die Set .222 REM (P/N 10901 Group A Dies) for sale. This is BRAND NEW, never used. There is a F/L sizing/decapping die and a seating die in a green plastic die holder box. £37.00 inc postage.
