Got out to the range today and was set up to give this a try.
Rifle: Cooper model 21 Leupold VXII 6 - 18 Flashlight taped to side to make it tacticool
Cartridge: 221fb 50 gr BK 16.8gr of AA1680 Norma brass Rem 7 1/2
Conditions were fairly good save a modest crosswind
These are two consecutive 10 shot groups on my homebrew targets at 100.
Group 1: 1.040 - 0.224 = 0.816"
Group 2: 0.771 - 0.224 = 0.547"
Average: (0.816 + 0.547)/2 = 0.682"
I said this before, but I don't regularly do 10 shot groups....I usually stick with 5. It takes another level of concentration to keep steady on all ten, for sure!
