i have a friend who thinks this bdc is the turnkey solution to his muzzleloading problems and its only the begining of some new ones imo.
While I would agree that a BDC scope is not the solution to any muzzleloading problems, they can be a very useful tool IF you do your homework at the range. This 3-9x40 Leupold just showed up on my doorstep yesterday, and when winter is over, I plan to wring it out. I will do a full report when I do. The thing I like about this scope is by just changing the power ring to another setting it will compensate for the drop in ANY load of your choosing. The center crosshair stays on zero for any setting, so I plan on getting zero at 100, then shooting at the other ranges using the crosshairs, then checking the POI with the other dots. By benching your rifle, all you have to do to check the accuracy is put the crosshairs back on the bull, the dot for that range should like up with the POI of the bullets on target. If they don't, just dial up or down in power until they do, that would be your setting for that particular load. I will do that with all my pet loads and by process of elimination, I will be able to figure out what setting will be best for each load. I am not saying this will be an exact setting for every bullets trajectory, but should work well out to 200 yards. I doubt that I would ever shoot further than that unless it was perfect conditions and the range and trajectory was known. I have heard guys say, I sighted it in at 100, so I am good out to 250. I say BS, you have to do your rangework to find where your individual load and rifle are going to print at those distances or those settings on the scope.
I hope people don't think that these scopes are the fix-all for shooting long distance, because if you can't already shoot long distance, you don't have any business doing it. I look at these scopes as a tool to aid someone that is already versed in long distance shooting, but also knows their limitations when they are hunting under field conditions and not setting at the bench. Big difference!
With this scope, it will allow you to tailor the setting to your load, versus loading to the setting IMO. That to me means several loads, from the 200 grain SST in my .45, to the 350 grain Hornady FPB or 460 gr No Excuses in any of my .50's. I will just have to do the rangework first, and figure out the best trajectory setting. I don't have any grand illusions of shooting out to 250 or 300 yards in the field for deer, so this should work well for me. I may shoot out to 300 yards at wood chucks with my .45 Elite loaded with 120 grains BH209 and a 200 gr SST or lighter bullets with an appropriate charge once the trajectory has been all figured out.
