Shot a couple hundred 18.1s yesterday, all from the 1:22 SubMOA barrel. Some of that was the 150 yard pickle jar lid fun mentioned above, and some was on paper @ 30 and 50 yards.
So, reg pressure of 125bar, plenum stuffer and a transfer port restriction in place, white spring on "12" produced 880fps with the 18.13s. Lots and lots and lots of shots per fill. Very minimal cocking effort with the white spring. Overall pretty darn enjoyable.
Here are two "30 yard challenges." Shot them benched, which I think is my first time doing so, as I usually shoot them from a field target position. Per the National Weather System, the nearest weather station to my house (3 miles) recorded wind speeds from 3-18mph while I was shooting, and from various directions.
And this is the chrono date for one of the above, I didn't note which one...
From there I went out to 50 yards. Found some old printed N50 targets in my target binder so shot at them. BIG disclaimer here on the 18.1s @ resisting wind....I've got at least 6 different .177 and .20 barrels and guns that resist wind better than the .22/18.1s @ 50 yards.
I don't have a 0.35 plug so I set my calipers to 0.175 and measured from the center of the hole to assist in scoring, like this...

(Top row of both = sighters)
And then for scoring here's the math to extrapolate the 196/200 to a score out of 250, had I shot a full card.
So, by setting up ratios, it would have shaken out to something like a 245/9x.
I hadn't put many 30fpe shots down any of the barrels for the BW prior to this, but I found the experience quite enjoyable.
