From the looks of these threads, it looks like you're delivering on that 1-2MOA ballpark with the FR's pretty regularly. My B&D mag isn't an FR, but if I can't get it out as far as I want it, I already talked to Chris about having it converted over!
I'm half tempted to convert it to an FR anyway, I'd love to see what kind of velocity the 357/44 B&D Mag could do with a 10-12" barrel and a 1-2thou B/C gap.
As long as I can get keep it under 3-4MOA, I'll get what I'm looking for, at least in the short term.
