.45 with .440 RB, .018 patch, spit lube (forgot my bottle of Hoppes).
Fact - 30 years ago I was steady as a rock, now wobble all over off hand
Excuse - stiff breeze straight in face made wobble even worse
Shot 2 sets, sadly, set A was my best, B was terrible.
Target arrangement shown. The 25 off hand was standing, no rest; the 50 I rested forward hand against the post to left of bench while standing, which helped a lot.
I score the 25 yard as 13 and the 50 yard as 43.
