They say you can always tell an American, but you cant tell him much.
Seeems the old experssion is true.
In order, Eightbore, as part of a team I worked on guns that were built for Holland &Holland.Dickson,Churchill,Westley,Cogswell& Harrison, Bland,Linsley,Chubb Webley & Scott, Greener and few others.Since then I have rebuilt barrels for many major companies both in the UK and the US, without any complaint.
Piper, the parallel in question is the parallel of the bores on the hoizontal plain or vertical in case of an OU. So as when you look down the barrel one is not higher than the other. As a self proclaimed engineer I would have thought that was obvious to you.
Stan, you are talking drivel and you obviously have no idea about gun making . When you have been in the trade for 20 years come and talk to me again.
Work it out ,subtact the distance between centers of a SxS at the muzzel from the distance between centers at the breech , devide this by the length of the barrel in inches to get the taper. From this you can calculate where the center of the bore line should be at any given distance ,.You can then apply the same priceple to the hight of the ribs above the bore centerline to give the same.
When you have done this you will see that to build a pair of SxS barrels that will give an exact overlapping pattern ay 30 yards you will need the barrels spaced about 5/16" at the muzzel and the rib at the muzzel would need to stand above the barrel about the same. How many of you have guns like this ?????
