its the first time I heard about feeding problems with the CZ 527. any chance it was a monday made rifle?
the little CZ action see a lot of use here but in .222 what is the legal minimum for hunting roedeer. so far the .222 is also used for shooting the special "hunting " disciplines and this rifles make thousends of round's a year. the 7,62x39 is a little bit obscure because its connectet with the AK 47 and this is a "terrorist gun" in the public today. doesn't mean shooters dont like the AK action in a sporterized gun but there are not many hunter's using them.
the real king in this class is with no doubt the .223 rem today which shoot flat, is very precise and kill anything from fox to roe deer. and you have a much greater selection of guns!
if I dont had a special taste the CZ 527 would have been my choice in 7,62x39. no doubt the mini mauser action is much smaller and handier than the carcano.
