I have a Knight T Bolt from the late 1990s (probably 97) that I haven't used since around 2000. I will have a cow elk hunt in Colorado later this year and I'm trying to determine if I should upgrade the T bolt to a 209 primer conversation kit or if I should replace it with either a Knight Ultra-Lite, TC Encore Prohunter XT or a CVA Accura MR-X? I grew up muzzleloader hunting with a traditional muzzleloader but haven't done it since the late 90s. Thoughts?
