I played the "frame game" too, and until just after the 2000 SHOT Show had 20 Contender and 5 Encore frames. I want the barrel locking bolts matched to the frame the barrel will be shot on, and so set up groups of "like" barrels for each frame.
Dumped the Encores completely, and nearly 90 factory Contender barrels - so also cut back on the frames. Only have 5 EO frames now, and they handle all my custom wildcat barrels just fine - again dedicated in groups of barrels per frame.
