So I took my 5" Model 29 Classic with Burris Fastfire RDO out Sunday to confirm zero, and to readjust the zero for 150 yards.
It only took a few shots to re-adjust the sights as I had previously been zeroed at 100 yards.
I only had time to shoot 2 groups, but I figured I would share the results. Once I made my adjustments, I shot a 3 shot group on one target, and a 5 shot on the other.
I was using the old Elmer Keith method, leaning against an object, which in this case was my truck tire, bracing the revolver between my knees and shooting.
This is 5 shots at 150 yards.
For reference, the circle/target is my highly precise Folgers coffee can lid that I used as a template to spray paint
The load is a 240 grain hard cast powder coated hollow point pushed by 10 grains Unique.
The 240 Cast/10 Gr Unique has long been my standard mid range load and is a pretty solid working load.
