That looks like it could have been funI took my CZ 457 to an Appleseed Rimfire Known Distance (KD) shoot this weekend; shot a 50/50 on the 100 yard course and a 49/50 on the 200 yard course (the white sticker at 10 o'clock in the photo is the shot I missed; dropped it on the 150 yard stage).
Course of fire for the 200 yard course is:
10 shots offhand at 50 yards, 2 min time limit
10 shots seated at 100 yards, transition from standing to seated, 1 mag change, 55 sec time limit
10 shots prone at 150 yards, transition from standing to prone, 1 mag change, 65 sec time limit
10 shots prone at 200 yards, 5 min time limit (these shots count double)
Same course of fire for the 100 yard course, except the ranges are 25, 50, 75, and 100 yards, and the target is 50% smaller.
No bipods or bags, just slings.

Since this is the cz thread, I am dumping my harrells tuner, ready for a 457 mtr barrel or others at .860"
