just saying, you saw what the kit looked like before you bought it.

Finally dialed in.
What a pain.

After chasing my own tail for a while, because it didn't dawn on me over the past couple weeks to shoot a separate target for each sequential load from a clean bore, I eventually figured this thing out.


Based on the current zero:
Clean, greased bore goes way low and way, way right. (~14" low and ~36" right @ 100 yd)
Second and third rounds stack up nicely, right at the POA.
Fourth round goes 5-7" high and 12-18" left.

There's a lot of machining chatter on the land at 9 o'clock (3 o'clock, looking from at muzzle). And there's a nick in the crown at about 2:15-2:30 (10:30-10:45 looking at muzzle).
But, neither of those should be causing a variable divergence issue that is also influenced by fouling -- especially when considering gyroscopic precession and point of impact.

...The stupid thing just doesn't like to be clean.
(Or very dirty.)
