Just heard about this thread, very interesting! Some real nice rigs/shots out there.
This picture and attempt was taken before i saw this thread, and my attempt didn't fully comply with the rules, but this is my 5 shot group (minus the flyer' at the bottom) at 50 yards using my custom Ruger 10/22 and a 3-9x40 scope. The barrel is an 18" Green Mountain .920 bull barrel with Benzt match chamber and recessed target crown. The group was not measured with calipers as you can see, but i placed a tape measure (only thing we had at the time) to get an idea. It appears the group is between 1-1.5cm
This is the part list i have already installed or will be installing in the near future. Almost $1,000.00 into her and i still plan getting much better glass... #moneypit (and yes, i just used a hash tag
