Report-- Went to the range today, armed with 2 factory loads, and several cast ones- the Sab will not keep both barrels on paper at 50, with anything I tried! Shot about the same with all- R was 4" low and 4" right, L when I finally found it was 12" left, and 6" low. So, back it goes- kinda a shame, because it really fit me! No sign of the Dremel regulation on this one, although there was one where I got this! They are still out there for sale new! Guess I'll keep looking- would like a 45-70 double, heck, I can shoot it cheaper than a 22 if it would regulate!
