I wish I could use iron sights and do that well, gizzy.
My optometrist says that not only do I need glasses, so do my rifles.
And offhand? Forget it... I'm all over the backer.

I do almost all my range shooting at 200 yards.
With rimfire you can calculate what the spread would be at lesser distances
from the results at 200 yards. My last attempt with Norma Match,
produced 12 inches of vertical at 200 yards. Apply the half-third rule,
half the distance will give you a third of the spread, under similar conditions.

So 200 yards, 12 inches, quartering headwind at 6 to 8 mph.
100 yards, 4 inches.
50 yards, 1.3 inches.
25 yards, 0.4 inches

Ouch Hey wonshott, be careful about pulling on the Tiger's tail You seem to be an experienced shooter but have you been following Jaia's work AT ALL here on RFC? From what I can see, he know's his .22 ammo and puts in a tremendous amount of time testing ammo @ 200 yards.

When you do the "challenge" make sure you use a different POI from your POA such that the 50 shot group will not obscure your aiming point. You probably already KNOW this but just sayin'... I'm interested in seeing your 50 shot group @ 50 yards with this ammo as well, so get to it! I'm prepared to eat a little crow if your group turns out to be appreciably less than the 1.3" Jaia mentioned. Be advised, though, it takes just ONE flyer out of fifty to spoil the results. I just shot a 40 round prone/sling match @ 200 yards this past Saturday, and a couple fliers (well, maybe MORE than a couple) sure spoiled MY target! So NO cheating, do fire all 50 rounds into the group

All 50 shots on a single target does keep it interesting.
Most make noise, then never back up their claims.
While I'd love to contribute with "Results on Paper" part, my observations were that the particular lot# I got during the "Great Midway Norma Clearance Event of 2018" (What I called the $33/brick sale of the White box Match) shot absolutely phenomenally through my KIDD barrel 10/22. Through my CZ455 and 457MTR (both stock/factory action/barrels) the results were in the "pretty decent but they've shot better" category.
At today's pre-panic prices of $60'ish a brick, there's no way I'd buy more.

My chrono results were considerably better than Jaia's, but nothing to persuade me into dusting off the old Delorian, firing up the flux capacitor and getting any more for the $35 pricetag:

My labradar suggested the following over 50rd
08-18-2019 - CZ455 16.5" barrel
Average 1093.22 fps
Highest 1127.68 fps
Lowest 1064.51 fps
Ex.Spread 63.17 fps
Std Dev 15.2 fps

08-18-2019 CZ457MTR 20.5" Barrel: (Partial box, 40 logged shots)
Average 1135.49 fps
Highest 1154.43 fps
Lowest 1110.96 fps
Ext Spread 43.46 fps
Std Dev 12.16 fps

Thanks for posting the numbers dave, considerably better than the last order I received.
Still not what I would consider match grade with that ES over 40 fps.

As long as each 5 shot group is sent using the same scope settings
and a known aim point for each group, with a scale reference I can build the 50 shot aggregate.
That way the flyers will show up and not ruin all the rest of the groups.

jaia, i shot my 50 round box of norma match this morning. i was using my modified ruger 10/22 with 20 power scope. i couldnt feel any wind from any direction. Sorry no chronograph. the group was very rectangular in shape measuring .811 inches vertical and .535 horizontal center to center. thank you for opening my eyes to this vertical dispersion. when i think of short range plinking ammo, i think of remington golden bullets. norma match is not in the same category as golden bullets.

Now you know how I felt when I started testing with 50 shot runs.
Up until that time I was doing pretty good with sub-moa at 50 yards for 5 shots.
It wasn't until I started recording chrony numbers and documenting targets and group aggregates
that I started wondering where all those odd flyers were coming from.

Feel like attempting 50 at 100 and 200 yards?
You can double check my half-third rule.

Any pics of results/rifle/range and setup?
I like rifle pron.

Thanks for giving it a try, not many have.

That's not bad at all W. Actually pretty good for a midgrade 22lr cartridge.
When you do shoot those 100 and 200 yard groups of 50,
I'd like to add the results to the 50 at 200 thread in the RFC long range forum.
The more results from different rifles and conditions, the better the discussions.

I was under the impression it was reboxed Geco Match Rifle. Iíve shot a lot of the Geco and at 25yds. Itís shoots as well as standard +. At 50 it opened up Geco sells at Target Sports for $30 a brick
Some of my rifles shoot it well, most shoot the Semi Auto better. My 52 Pre A shoots it as well as SK Rifle Match, again 50 yards not as well.

Hey wonshott---nice shooting there! Looks like a CMP Rimfire Sporter target you were using? Using your proven 10-22, with a 20X scope and no wind to speak of, that .811 vertical stringing is certainly due to the extreme velocity spreads within that box of 50. As you noted, it IS an eye opener and turns those tight 5rd groups we all shoot into, well, that .811 x .535 group. I do think that is still VERY respectable for a fifty round group. Thanks for posting the target.
