I bought the scope last December 2020 from cabelas. I watched videos of shooting on a 50 caliber muzzleloader. I now have it on my Thompson center encore magnum gun and contacted Burris fir a drop number. The velocity is 1846 and the bullet coefficient is .210 as given by Cabelas staff zak. Burris tells me I need to send it back and get a eliminator 4. I am looking to shoot up to 300 yards. Can anyone give me some guidance. I am looking for a drop number for the scope.
