Appears with that load, the bullets would cross about 2"(just a guess) at 100yards, and be about zero'd at that range, if the rear sight was moved slightly right to compensate for the left impact.
That probably isn't bad, however longer ranged leafs would continue to spread.

Slightly less powder, or slightly more - or different wads the change the recoil characterisitcs might spread the barrels to more parallel impacts and drop the poi slightly.

A change to 350gr. might also have that effect, or might increase the current tendencies.

Looking pretty good, but 2 shots only makes it very difficult to judge accurately.

2 or 3 sets of targets of 2 shots each will be present a more accurate picture to judge.
