My server won't connect with the server hosting the 25 yard target -- I e-mailed robmints for the actual RFC target.
In the meantime, I made my own 25 target: Outside dimensions of the black circles are 0.360", inside white area is 0.200" - I think it's slightly smaller than the actual 25 yard target. But when I get the target from robmints, I'll use that in the future.
Tried it last night, around 7 pm in 92F heat and 90% relative humidity. I was sweat soaked after the 25 rounds and called it good enough. The target doesn't look too good, but I scored it with a plug made from an unfired 17m2 round and scored it as a "20". Here's the target:
Here's the gun, a CZ 452 American in 17m2 with a Leupold 3-9x33EFR scope:
I was shooting Eley ammo, and I've got Hornady and Remington 17m2 ammo, going to give those a try and see if they do any better.
