The reason that will not work is that the release base for the old Howa is spaced differently than the new ones, which are the same as the Rem 700. I can get the old Howa base from a liquidator, but the Luepold chart only shows current production runs. Can I just use the Remington 700 base chart and believe those rings heights will be correct? I'm thinking so, but don't want to get burned.
