I have 2 Encore muzzleloaders and the each have there own scope.
I have 2 Encore pistol frames, a 30-06, 22-250, 7mmBR and 44MAG and they all wear there own scope.
I have A contender frame and I have a 444Marlin and a 44MAG barrel that wear there own scopes.
I do not like to have to change scopes. I sight a gun in with a particular scope and I make adjustments for different bullets. I have scopes from Burris 3X9X32, Weaver 2X8X32 and a lot of Leupold scopes in 2X20mm EER. My variable scopes, I use on my long range shooting pistols and the Leupold 2X20mm I use on my shorter range barrels. Just a hassle having to sight them in all the time. JMHO.
