it is not supposed to work I know but I shot 5 rounds from the CZ 527 Carbine with 12 twist 18 inch barrel,,5 shots were just under one inch and all holes looked round and no signs of key holing,|
anybody ever tried this ?? you think it was a fluke or will some 12`s actually shoot the 69SMK,
load was with LC brass CCI 400 primers and 25 grs Varget and the 69 Sierra bullet..
