one thing i have heard is that CF will chamber evan if the gun is upside down. its supsto be more relibal on feeding and extracting. maybe CF are my pf will chamber upside down to. of all my shoting with pf i have never had a problem with it feedig or extracting. the only falure of a bolt gun i have had was with a surplus 98m. the claw broke. so i dont know if the cf vs pf is that big of deal. Btw on the falure of the 98 i loaded it from the mag.idid not force the bolt over the cartarge.

but from what i have read the post 64 mod 70 it was not just the change from cf to pf that caused the problems is the fact the whol gun was redisined and looked and functiond cheaply
