I just unloaded two CDL SF's one in 257 the other in 7mm rem mag. The Rem mag had crooked chambering. The 257 did not shoot as well as a Vanguard 257 I owned a long time ago.
Who the heck would knowingly buy a rifle with a crooked chamber?
Does your dealer allow you to borescope rifles prior to their purchase? Now STFU and stick to the political forum.l
