As far as the shooting went, I can only comment that I fought elevation mostly from what was expected from GA settings. Seemed like I was trending low until I overcompensated high!
Darkness wasn't an issue most of the shoot with the longish day, but the lights came on near the end and I got to try one bank of white painted rams. Very cool! Didn't hit much, but it certainly wasn't for lack of target definition. Wanting to try this when it gets dark sooner. A full night shoot would be great!
Some photos:


The "IHMSA Cage". Note the bank of lights above the roof. Worked well.


Running low of the one lot of Federal Value Pack that this revolver really likes. Seems to have better terminal ballistics on squirrels than most other ammo as well.


Not a good run on the rams, but rack it up to operator error rather than conditions. They fairly well glowed!
I want to try this again! Bit of a drive, but hopefully will get some more shoots in in the not too distant future.
