Forever. CVA rifles all have excess head space, and have had excess head space for a long long time.

Years ago, i made shims to reduce head space of the old model Accura, and later used them in the new model Accura too.
















Ironically, this excess head space is helpful if one wishes to use the metric o-ring to reduce blow by. One can take almost any CVA rifle, stuff the o-ring into the primer socket, and shoot it. Far and away the easiest way to solve blow by, of any rifle. Western Powders even includes some o-ring with their breech plug. One cannot do this in TC rifles; head space is consistently near perfect.


Another thing done years ago, was to make breech plugs that would reliably ignite Blackhorn in CVA rifles. These plugs were intentionally made several thousandths longer than factory plugs, because the rifles had excess head space.
