More on the 221 fireball
Well got the CZ 527 in ( 221 fireball cal.) and adjusted the trigger , it has a set trigger 21/2 and the set is on 1 lb... I reloaded a reduced load for it. CCI 400 primer, 700X power, hornady 35 gr. V-max bullet. The power load ended up at 3,5 grs.. Shot it at 50yrs. and got a 3 shot group at .147". I have not checked how fast it is going yet.
