As for the Lightning, using factory fodder, it groups pretty well. Low charges resemble a shotgun pattern. I'm playin around with several powders, with loads, still under Max charges. I found Hornady listed both Rifle and Handgun loads which helped explain the significant charge differences between the books, using the same powder.
I'm using the same bullet you're casting, but I don't have the time to cast and size, in spite of having the equipment, but I do have two good bullet casters I can buy from. One with a Magna-Caster and the other producing good quality big bore rifle bullets in smaller quantities,
As for your wet, then dried primed cases, it sounds like they've dried sufficiently to use. I'm not sure I would use them for an important match, but practice wouldn't be an issue. Any misfires, you can use the old RCBS hammer and salvage the bullet, powder and brass.
The thing I might be concerned about would be any changes to the primers flash temperature, as a result of the soaking, causing squibs. I'd load a sampling and make a trip to the range and give them a try.
Now:Now, GET OFF MY DRY LAWN!
