I always suspected the forearm screw but the old 99F had the stud attached to the forearm and not a screw/stud and had the same POI problem.
I noticed that the stud is looser as the weather becomes drier.As I said, I don't cinch it down real tight as I am afraid of cracking that slender piece of wood.
An analogy would be this; I have a tomahawk with a steel head and a hickory handle. In the summer the head is tight as a drum but in the winter it's so loose you can wiggle it up and down. I'm sure you've seen similar.
I always seal the inside of wooden stocks with True Oil or LinSpeed but probably doesn't help much since the outside has the original finish.
If I test it w/o the fore arm I'm fairly certain it would hold zero but then what? I would have narrowed the problem down but what to do about it?
