Landy, on the Target Data image the Target Distance indicates 50. For clarification, should that be 200?

By the way, that image (or whatever the term is for one that changes) is a very good illustration of the changing results.

Yup, good catch....disregard the angular measurements and look only at the raw statistical metrics under inches. Or, use a divisor of 4 for the angular measurements.
The image is a GIF.

Eley Semi-auto Benchrest Precision 40 grain 22lr, rated 1080 fps

Lot # 1219-02321

Why did I offer the lot number this time?
Very surprised by the chrony numbers from a midgrade cartridge.
ES of 29 fps for the first 50 shots, 25 fps for the second 50.
Had to check the numbers twice on the chrony...thought I was reading it wrong.

Daaaayyyyyyuuuummmmmmm!

That's better than my results with ammo costing much more per round.

CZ 455 Varmint, Lilja barrel, Sinclair bipod, 200 yards



Clear lubricant, no plating, looks like a new cast lead bullet just out of the mold.
Minimal visible defects, clean uniform crimp...good looking cartridges.



Freshly cleaned bore with the chamber scrubbed to clear the carbon ring,
and started out by sending 5 at the steel to fine tune the scope.
Then the remaining 45 on target. Vertical is tailwind and clean barrel.
As the barrel regained it's lubrication, trajectories tightened up.
I could see the bullets spinning into the backer in tighter and tighter paths.



The second 50 did extremely well, even with the tailwind.
Fully lubricated bore and a better feel for the wind changes on my end.



Really didn't expect this new cartridge to do this well.
I'd buy it again. It'd be some very decent hunting ammo.

Jaia- I appreciate what you've done here with showing consistency (or lack of) with.22 rimfire. Honestly. But I'd prefer groups of 50 shot at 100 yds. which is more practical for me. Just saying. As with all suggestions, feel free to ignore.

A, you know what to do, right? Apply the half-third rule.

Tailwind at 2 to 5 mph with this box of cartridges,
ya' get 5 inches at 200 yards, expect 1.7 inches at 100 yards,
0.57 inches at 50 yards and 0.19 at 25 yards, for a 50 shot group.
Can't offer much more information than that, right?

A dime is 0.705 inches in diameter.
0.57 plus 0.21 = 0.78 inches.
You could just about cover all 50 shots with the dime at 50 yards.
That's pretty decent for a 22lr, eh?
