The following photographs are of Steve Cranston of Holland and Holland regulating one of their .577 Nitro double rifles. Steve has been doing this for over twenty years. These were sent to me by a good friend, Stephen Howell, who asked me to help him get these put up on here for your enjoyment. In one of the photos you will see that he is heating the barrels up and putting on more rosin before he makes an adjustment to the front regulating wedge. If this is the way he does it, especially with a heavy recoiling rifle, you can bet it is the best way. Notice the placement of his front hand and the cover they put over this brand new gunstock to protect it.
This is a direct quote front Steve Howell that he sent me with the photos.
"Steven Cranston of Holland and Holland has been regulating barrels for nearly 20 years, and to my mind knows more about it than anyone else in the world. The 4 shots were at 50 yards after he moved the wedge in the flaming photo. Steve also does the final choke boring for pattern centering of Holland shotguns in order to get it the way the customer wanted his new shotgun to pattern. It is all in the Holland & Holland video titled: " A Look Inside Holland & Holland" which is available at "www.gunmakersrow.co.uk or from Holland & Holland in London and New York shops. I paid $50.00 for my copy 3 years ago. It is a one hour video of all he facets of building Holland & Holland guns and rifles."
