Hello 500Nitro,

Yes, very good observation. Actually, R1 L1 R2 L2 were fired first. I had loaded 6 rounds with that load, but initially only fired 4 of them. After testing the other loads, and after the rifle had cooled, I fired the last 2 rounds of that first load. I think I had learned a little better of the trigger control at that point, and they printed a tad different than the first 4 shots, albeit in the same group.

As far as aiming goes, the front bead fits nicely into the black ring with a sliver of white showing around the bead. My old eyes can't see a 1" white sticker at 50 yards.
