Probably not, it's going to remain a niche market that grows smaller & smaller every year
Without a doubt the British box locks are better guns compared the Stoegers out of Brazil or the various Turkish guns, but you don't see, at least here in CT, British box locks on the racks of the guns stores.
Who is going to introduce them to a SxS? It's great that high schools and universities have skeet & trap teams, but what guns are they using, almost certainly O/U or semi auto.
I shoot skeet and scap (wobble trap from the skeet stations) almost every Sunday and almost always with a British hammer gun or side lock for skeet. My friends think the guns are interesting and appreciate them, but they aren't going to spend the money for one and here are some of the reasons:
Cost of the gun, cost of ammo for the 2.5" shell, cost to repair when they break (not counting finding a qualified gunsmith to fix the gun that doesn't have a significant backlog) double triggers, lack of interchangeable chokes.
If you're young and a new shotgun user, why spend $1000+ for a used, perhaps tired looking British box lock when you can by a CZ for under $700 that comes in a hard plastic case and with 5 chokes?
