Hey Numero Uno...you guessed it. My #1 (which I call a #1 S26M) does have the BB etched in the hanger. I didn't even know that was there. All that cool stuff aside, what really gets me about the piece is that it's the tightest #1 I've ever seen - no jiggles or rattles anywhere. When that lever shuts, it shuts tight, smooth and silent. Second, it will shoot 150s, 165s, 180s and 200gr bullets all in very acceptable hunting groups. And I have particular recipies with 180's that are better than acceptable, and a couple 165gr loads that are just plain great. Thanks for the insight!
