Rick: IMHO, you totally miss the issue. Who cares what a manufacturer claims about their product?
Obviously, you don't. You're warning about external chokes while Briley has been making them for quite a while with excellent success. It is apparent you believe that the sun rises and sets on Stan Baker, but he isn't the sole authority on shotguns and chokes that ever graced this planet.
Come to think of it, if I don't care what somebody claims about their product or work, why would I care about Stan Baker and his work?
Now that wouldn't be very smart of me - no smarter than saying I don't care what Briley, or Lyman, or any other successful and reputable manufacturer says or sells. Or does that rule only work for folks other than Stan Baker?
And that IS the issue. You're blind to anything but what Stan Baker told you. Which is fine - I'm sure that works for you. And I appreciate your repeatedly making the effort to offer me your warning. But I don't see the world in quite as narrow a light as you do.
They are in the business to sell what they produce.
This is just a guess on my part, but I'll bet Stan Baker was in the business of selling what he produced as well. And I'll also bet he made more money when he convinced somebody that something like a Cutts would fly off their shotgun and they should have him install some of his custom chokes instead.
Anybody who wants to stay in business long promotes their products/work and tells you other alternatives are inferior. That's just the way it works, and I am quite willing to believe that most of the sellers do believe their approach/product is indeed the best.
Stan Baker knew more about shotguns than you and I will ever know.
Probably did. Reminds me of another expert named Jeff Cooper who said the 9mm was inadequate as a fighting handgun cartridge - something the real world has shown to be false. Even those who sit at the right hand of God have their own personal prejudices and don't get everything right.
On the other hand, Briley and others out there aren't exactly unknown, and they appear to differ with your view of the situation - and not only have been quite successful at it, but don't appear to be swamped in lawsuits from chokes flying off in the marsh, barrels splitting, etc.
Give it up my friend, and buy a shotgun choke tube system suitable for steel shot.
I've never been much for "the sky is falling" stories that aren't accompanied with at least a reasonable supporting argument, thanks.
So far I've heard the dire warnings, but nothing to support them. No evidence of these terrible things happening with any regularity, and no evidence these loads would stress a choke more than heavy magnum loads of big shot.
And if she does really take to hunting waterfowl, then we probably will look at getting her another shotgun. But for trying things out, this will work fine without causing the end of the world as we know it.
