I had a nikon buckmasters on mine and I thought the field of view was to small.I do not like the muzzleloader scopes with the BDC.In my opinion it forces you to shoot a 250 grain bullet with 150 grains of powder.What if your gun don't shoot it well?I think a bdc crosshair is a waste of money.Please keep in mind that it is my opinion I'm not saying they don't work.
