I don't understand - in the first post, the gun is shooting 10" low. In the second post, the gun is shooting very high?

On the Kodiak, you can replace the front sight with about any 3/8" wide dovetail bead sight that is higher to make the gun shoot lower, or lower bead to make the gun shoot higher. Williams and Lyman make rear bead sights.

Conversly, raising the back sight makes the gun shoot higher, lowering the rear sight makes it shoot lower.

Increasing the powder charge can, in some guns, make it shoot lower. This is usually with guns that have very little recoil impulse, like small bores.

With a gun that has 'some' recoil, increasing the powder charge will usually make the gun shoot higher - in muzzleloaders, that is.

Ctg. guns of large calibre (& handguns) and low velocity, usually shoot higher with light loads, lower with heavy loads - when using the same projectile.

I know some people are using much heavier loads in their 12 bore Pedersoli's, but I doubt the maker warrants such loads.

Since the barrels shooting fairly close together, I would not increase the charge, except for hunting, to about 120 to 140 gr. & of course, re-shoot to test point of imact and group sizing with that load. You may find that much powder is about all the recoil that's fun. You adjust the rear sight's height to get the balls centred - or - if the sight will not go high enough, or low enough depending on where it's hitting, replacing the front sight with one higher (lowers POI) or one lower(raises POI) is the next move on your part.

A .715" ball sounds small for such a thin patch. Put another way, the patch sounds too thin to give good accuracy and clean shooting that doesn't require any wiping- at all for an entire day's shooting. When the patch is right, no wiping is necessary.

POI is point of impact.
Here's a short loading video showing the process of loading a .58 cal. Kodiak.
