The Nikons are very good,especially the Omega which is designed for muzzleloaders, some people do not care for the circles reticule but if you know how to use it it is very good for long range. The Nikon with the military reticule is also very good. I believe that the next best are some of the Bushnell the value per dollar is very good on a Bushnell. I have had a number of other brands, some supposed to be very good that failed under the recoil of muzzle loaders but if you use light loads all of the time a lot of them will work.
