GDay guys, I have a few questions regarding regulation, if you will permit me...

I am assuming that the major cost involved with building a double rifle is the regulation of the barrels for same impact point at a given range with a given load. Otherwise they would be as cheap as a SxS shottie. I understand the barrels are soldered together and tested then 'regulated', tested again and so on until they are right. True? Time consuming!

I don't like the idea of the jackscrew on a moveable barrel like has popped up of late but surely there has to be a better way to do this in today's age! Don't you think? This may seem stupid but why couldn't you get your two rifled barrels which have been chambered and a laser to fit each and simply line the lasers up together at whatever distance, then join the barrels together and develop a load to suit?
