Do you think George Digweed worries about COB CG and MOI?
Just learn to shoot.
Bless you Joe. Yes, I will learn to shoot. And I think George Digweed thinks about everything, then closes it out, and then focuses and shoots.
The point of the initial question is about where the CoB should fall on this given gun. It is a purely subjective and speculative question.
The gun has been restocked and I believe the stocking might have added 5-6 ounces or so to the gun.
The gun has three weight barrels, other three weight barreled guns weigh in the 6lbs 8oz or so range, not 6lb 13oz range it currently sits at. Yet the gun balances where most of us normally think it should, on the hinge pin. Minor experiments at adding 5-6 ounces in the range of where the opposite weight falls shows it might have been 3/4 inches in front of the hinge pin if my theory is correct that the restocking changed it.
My research has shown me that Fox did custom guns with CoB in front of the hinge pin by as much a 1 inch (possibly more) so it is within the range of probability even a Sterlingworth could have been so built (this one was built with at least two barrels. I have written for a factory letter so we will see if there is anything in the old files. It is likely that those details if they existed will not be there.
I agree with what others have posted about shooting it for awhile to determine if the CoB agrees with me or not before altering. That the actual feel of the gun is more important than a particular CoB point.
I further agree that the CoB in relation to the trigger hand is more important than the hinge pin, but I caveat that statement with the added observation that it also depends on where one habitually places their hand on the forend. Ultimately as pointed out by Rocketman it is preference.
This gun is only a fowl weather back-up as I could not resist the three barrel set and I always regretted selling my Fox years ago. The questions about this gun and CoB are esoteric and part of what I do on every gun which is to make every observation possible and know all I can figure about them.
