I think I've come up with a useful scenario...maybe.

50 shots at 200 yards, rimfire, whatever setup makes you happy.
22lr, 17 hmr, 22wmr, 17hm2, 17wsm, all brands, all types.
Full benchrest setup, bipod, bags or one-piece test rest, it doesn't matter.
Grab a chunk of cardboard, about 14 inches by 24 inches,
set an aimpoint at the top/center, dial y'er scope up
so the poi is about 10 inches down from the aimpoint. (5 moa)

Post a picture of the results with a 12 inch ruler alongside the 50 shot group for reference.

Include a pic of the setup, the box of ammo used, and if you have a chrongraph
the high, low and average muzzle velocities of the 50 shots.

To avoid having to hunt the entire thread,
in order to find the results with a specific brand of ammunition,
the links below are in alphabetical order by brand name and type.

Example: Brand and type of ammo Link to post

### indicates best results so far

You can calculate what the results will be at lesser distances by applying the half-third rule.
Half the distance produces a third of the spread.
At 200 yards the 50 shot group measures 9 inches of spread
At 100 yards expect 3 inches of spread, at 50 yards you'd get 1 inch of spread
and at 25 yards expect 1/3 inch of spread for 50 shots.
Useful if you are looking to compare the results for accuracy at lesser distances.

This sounds like fun, although the wind we've been experiencing in North Texas lately will make it challenging.

I'll be doing it with iron sights and a lever action 22, to keep it interesting.

Heck, I may dig out the Vostok with peeps then. Love shooting peeps at those distances, just need something big enough to see to aim at.

Is there a reason why the POI is 10 inches below the aim point? Why not have both the same?

It's easy enough to keep all shots on a 14x14 inch target.

Vertical spread is the reason doubs.
I do almost all my range shooting at 200 yards.
1 fps difference in mv is 1/10th inch of vertical spread with standard velocity 22lr.
I can destroy the aimpoint if I zero there. A substantial number of rounds will hit tight
but the strays caused by mv differences spread vertically quite a bit.
Add a tailwind, or turbulence, the vertical for 50 shots can be 14 inches top to bottom.
With the aimpoint above the group it's there for all 50 shots.
Put it at the zero point and there's a good chance it'll disappear halfway through the run.


Here's a starter to give an idea of what we're looking for

CCI SV 50 shots
High 1103 fps
Avg 1066 fps
Low 1018 fps



CZ 455 Varmint, set trigger, Lilja barrel, bipod and bags, Mueller 8-32x44



and the results at 200 yards
Wind at 4 to 8 mph swinging from my 7 to my 4
about 8.3 inches of vertical spread

Looks like your POA would have been safe from being "shot out" at any place on that target jaia. But, I guess that you've got a point if it's the shooter that posts frequently about shooting at metal eggs at 200 yards and hitting something like 50 out of 50. Maybe he'll try this game and show us how it's done.

Later,
Johnny

Thanks for explaining. When I have the chance, I'll try it both ways.

Here's a quick 10 shot group at my 16" gong set at 220 yards. The wind is howling at about 20mph over my left shoulder. First shot blew about 6" to the right at 3 o'clock. Held left and shot the 7 round group, which measured 6.5".

Shot the last 2 off hand, which landed at 12 and 2 o'clock.

Gun is a Winchester 9422 with iron peep sights. Geco rifle ammo.

.17 @ 200 yards, video

Here is a video in light air of a .17 HMR at 200 yards. A tad over two inch group.

In the RFC CZ forum, we have the 100/200 yard challenge.
If you want to see sub-moa rimfire at longer range, look at the posted results.
We've been doing it for a couple years now.
Every month different targets and scoring methods.

Here's an hour and a half spent with the CZ 455 Son of Fuglie Lilja 17 hmr
on a Sinclair F-Class Bipod. Set trigger, Mueller 8-32x44 target model
Near calm, variable, 85 degrees F, minimal mirage






Vertical spread of 5 inches is due to muzzle velocity differences.

Same setup





Large circular pattern is caused by bullet seating.
ES is only 100 fps, not enough to create that much vertical.
100 fps would produce about 3 inches.
Seating depths varied and roll a cartridge on a flat surface
the bullet tips had a visible wobble about the axis of rotation.
Not a surprise to see such a large pattern from poor bullet alignment.

Iron sights with lever gun at 200y.

12 " round gong. Shot a couple of rounds over the top before adjusting the elevation to the sweet spot.

Iron sights would be a waste of time in my case.
My eyes are so bad the optometrist said not only do I need glasses, so do my firearms.
He's not lying.
