I have these type of scopes in Burris,VX11,and buckmaster (with the half mil dashes) and they work great,but it takes a lot of shooting finding what power setting for different bullets and speed.
At present I have the VX11 blistic dot on a savage muzzleloader and it worked out to be dead on at 1,2 and 300 yds.Have had the buckmaster and burris on it and they worked out the same.
Would like to try it out past 300 yds but our range only goes to 300 yds.
