I like heavy loads, with a muzzleloader they are hard on scopes. I have had Swift, Redfield and Tasco scopes that the recoil knocked out and I have a couple of Weaver 2 power I have had for over 25 years that are still good and some Bushnell variable power for 10 years that are still good but the Nikon Omega is what I like the most though I have only been using them for about 4 years.
