The nikon's are good scopes but I shoot Burris Fulfield II balistic plex scopes on all of my long guns, and my Encore Muzzy. They have held up to any and all loads and bullet combinations, and I'm slowly replacing all my pistol scopes with them.
I guess I'm lucky as I can squint and still see the sights on all of my side locks, but I know in a couple of years I am going to have to go the "Semisane Sinful Sisters" route.
