Bill:
I will shoot with you. How about a 25 round match, 10-meter, standing, off-hand. Do you have Edelmann 5-bull practice targets by any chance? If not, then Gamo targets are OK, too. And if not that, then any target you want that you can post a link to that I can download it. I will shoot my AR2078a / .177 with the Tim Null stock.
If you want to go longer, weather permitting, I will break out the 2250 XT and we can go 20, 25, or 30 yards, standing, seated, seated w/ rest or bench - what ever. I could probably even find a 5-gal bucket for a bucket match. I do not do prone yet, and probably won't with the 2250-XT in any case. I guess I could shoot the Hammerli 850 in a CO2 match too.
You pick the distance and target. I will pick the CO2 rifle and shoot with you, what ever you choose. You have been called out, sir! Your honor is at stake.
