Building an MOA chart for a red dot Muzzleloader.

[CascadeHunter180]

I recently bought a CVA wolf with a Leupold RDS off of the classifieds here, and it has an MOA cap on it. It’s currently sighted in at 100 yards with a nice 3.5” 6 round group, but I’d like to build an MOA chart for it so I can dial anywhere from 50-200yards. Does anyone know the best program or way to do that with a muzzleloader? I’ve done it with my rifle before but I wasn’t sure if there’s something else I should do because it’s a muzzleloader. It’s a 24” .50 cal barrel and I’m shooting 100 grains of Tripple 7 with a sabboted 250 grain Hornady SST if that helps.

You shouldnt really need to do any dialing out to 200 yards (and Leupolds aren’t made for a bunch of dialing). Published speed on that load (assuming 2F) would be about 1928 fps. Published BC is .210. I’d plug that into a ballistic calculator. You should get something like this.

Just BC and velocity like everything else. Play with the zero distance to see what makes most sense to your area. A 150y zero is typically a bit more useful for muzzies for quicker shots to 200. Just don’t forget to really pay close attention to the wind, 10 mph pushes that bullet a foot at 200y!
