I solved the problem a few years ago by rethreading a Model 70 type front sling swivel to fit the stud on the barrel of my .300EG. I don't remember what the thread is and don't have the die readily at hand, but the diameter of the screw for Model 70 type swivels is large enough to allow you to turn the threads down with a die that fits the 99 barrel stud. You see the type of swivel I'm talking about in a lot of the Bishop and Fajen stock jobs that were done back in the 50 and 60s. I suspect you could do the same thing with a standard size quick detachable swivel stud.
