Last summer i found a place where i could shoot 400 yard. The drawback is, it involves shooting on an open ridge, where it seems the wind always blows. Even so, we had great fun shooting shooken pop cans with our AR rifles, but never did try shooting a muzzle loader there. A desire to shoot a muzzle loader at that spot has been growing.
The Optima i have been shooting this year seems to shoot moa, so it would seem it might work out at 400 yard. The scope mounted on the rifle has an elevation dial that is readily reset to zero, and the dial can be spun around and around so for to reach 400 yard.
A calculator was used to see how much the elevation dial would have to be turned, to reach 400 yard.
The calculator say to dial up 33 moa for this load to reach 400 yard. However, when i turned the dial it would only go 2 turns, and then reached the end of adjustment. So... i removed the scope, and shimmed the base with a piece of shim stock.
Afterward, with the rifle unmoved, the elevation dial was turned down to set the cross hair at near the same place it was before the shim was added. The elevation dial was loosened, and set to zero. Then the elevation dial was turned up until it topped out, which thankfully revealed, there is plenty of adjustment left, to reach 400 yard.
Now... it is time to sight the rifle in again at 100 yard, and develop a load. Hopefully a day will come thereafter, with minimal wind, which will allow a try at the 400 yard shot.
