DarrinG,
If you were using the same patch yesterday as you were a week ago we can begin with that
Take a compressedmeasurementof that thatching and we will call that a beginning point.
Bring your micrometer up snug in the uncompressed manner then holding with just your thumb and fore finger tighten the barrel of the mic and write down what reading you get. Uncompressed measurements of cloth fabrics are meaningless. The compressed measurement tells you what kind od seal the patch is putting around the ball.
On your next visit at the range load your rifle as usual but place a single sheet of thin paper between patching and ball and fire five rounds in that manner at 0 yards bench rest You say you lubed with mink oil but I have no idea how much you use I would suggest using as little as possible There are way to adjust the amount of lubrication but we'll go into that another day. If your groups with then first experiment with the paper are still wild try anoth five shots with two or maybe three sheets of paper between patching and ball and see if the group isn;t tightening up a bit.
a wild non group of no pattern is as igne of a variety of causes. Usually it means too thin a patching which allow some of the power to by pass the projectile,
OR too light a load, but I think your load is close to all right
OR too slick aPatch lube which allows the patched ball to zip out of the barrel like a hot suppository before the powder has been able to build up its maximum pressure.
If you get get a appreciably better group with a combination of patching and say 3 sheets of paper, take a compressed measurement of the patching and the same number sheets of paper.
that will be your new starting point.
I think your problem is going to be both too slick a lube or too thin a patching.
Let me know how you do.

We don'twant to clutter up the forum with all these instructions.
I hope you have been giving your bore a quick wipe between shots and that your wiping patches big enough to gather in the narrow neck behind the jag headand sweeping the bore clean.
Att the range we could accomplish more immediate success than this laborious method over the internet. but we may yet amaze yourself.
