As the title states, 50 shots at a single aimpoint at 100 yards.
Any rimfire rifle, or pistol, any caliber, any setup you like.
Not everyone has access to a 200 yard range, but most have access to a 100.
Let's see just how tight those clusters can be with ye'r favorite rig and the cartridge it "likes".
No rush, take ye'r time, use windflags and/or one piece rests.

Benchrest competitors...ya' don't have an excuse not to show what can be done.
Ya' don't even have to change the vertical adjustment on the scope, only the focus/parallax.
Just remember the poi will be 7 to 8 inches below ye'r 50 yard crosshair setting.
Here's a chance to show what can be done with ye'r custom setup.

That's 50 shots, all at the same aimpoint, at 100 yards.
Indoors, outdoors, offhand, bench, prone, are all acceptable.
Include pics of the setup, the view downrange, the cartridges
and the results with a ruler alongside the group for reference.
Include wind direction and velocity to see how it affected the trajectories.
You don't even need to chronograph the results.
We can figure that out from the vertical spread. :D

There are lots of claims of all day long,
let's see what really happens for just one box of ammo.
See if those "all day longs" actually hold up. ;)

I have some assorted leftovers from the 50 at 200 to work through.
Might as well send them at 100 yards as a comparison.

I'll link the results in order by cartridge and brand for easy searching.
Spectacular results will be highlighted for envious ogling. :rolleyes:

To review results produced at 100 yards in a testing tunnel see the 25 at 100 thread.

Not a broad assumption, Jack.
My comment is based on what is available in each state using the range search program.
Yes, you might have to drive a bit further than you prefer, but there are a large number
of rifle ranges and the majority offer 50 and 100 yard facilities. Whether or not you
choose to avail ye'rself of those facilities or to attempt a 50 at 100 is a personal decision.

https://www.wheretoshoot.org/

If you only have access to a 50 yard range, no reason you couldn't start a 50 at 50 is there? ;)

I wouldn't mind seeing results from that one. :D

Probably be more more useful as a reference tool regarding rimfire trajectory consistency
than those 5 shot wallet groups posted along with that famous phrase..."all day long". :eek:

Well had hoped to shoot my 17 today, had a doctor visit and was dizzy enough that I couldn't drive.... so had the wife drop me off to do 50 at 100 with my 1022. Have always found the best solution to medication induced vertigo is target practice.

Nothing makes for interesting groups like serious inner ear issues. On the bright side my groups were easily repeatable "all day long" . .. . Just picture t shot at 100 through a modified choke 12 gauge. Would give a measure on a pic but my tape measure wasn't in the truck and my phone doesn't have a wide angle lens.

Wife asked how it went, honestly I needed bigger paper....

Hopefully tomorrow is a better day and we'll try it again.

You too?
My Doctor prescribed Roids Monday for mine. Now I'm the angry guy that hasn't slept since Sunday.

How about that... it's a Saturday and it ain't raining. :eek:

Range gear is loaded in the vehicle, 22wmr Feddersen Fuglie is aboard.
Good morning to see what 30 grain CCI Vmax and 40 grain Maxi-Mags can accomplish.
People keep claiming the 22wmr is capable of consistent MOA at 100 yards.
We will see. Instigator? Who? Me? :D

CCI 30 grain V-Max 22wmr rated 2200 fps



CZ 455 Feddersen Fuglie barrel block, set trigger, Mueller 8-32x 44 target reticle
That is 18 lbs of inertia and stability...makes testing ammo very simple.
No skill required. ;)



Results at 100 yards holding a single aimpoint for 50 shots
1.7 inches of vertical, 2 inches of horizontal...definitely not sub-moa. :(



Visual inspection showed variations in seating depth, overall cartridge length
and several bullets seated at an angle/visibly tilted relative to the case mouth.
Rolling on a flat surface showed tip wobble.

I could live with that group from a hunting rifle .

CCI Maxi-Mag 40 grain hollow point rated 1875 fps



CZ 455 Feddersen Fuglie



Results 3.6 inches of vertical, 1.7 inches of horizontal



Better than Crackerjacks...three surprises in that box. :eek:

Irregular seating depths, tilted seating, varying cartridge dimensions,
typical CCI production.

Now that I've set the bar nice and low for 22wmr results,
I wonder if anyone has put their hands on some cartridges that can do better?
Shouldn't be too difficult. :rolleyes:

I'm going to have to resize the images for the 40 grain CCI.
Too high the resolution and the server times out.
I'll get it fixed Kirby. Stupid computers. ;)


Easy enough to resize/rename the images.
Took the image resolution down so each image size is less than 100 kb.
Looks like it solved the problem.


I agree with ya' Kirby...the 22wmr makes for a very useful hunting cartridge.
Flatter trajectories, more oomph on impact, ideal for center of critter.
It's just not going to be a "sub-moa all day long cartridge at 100 yards" for paper punching,
not even from that 1 piece barrel block monstrosity I use for ammo testing. :(

I'm hoping someone has a better batch of 22wmr and will send a box for us.
It'd be enjoyable to see that one of the manufacturers gets it right once in a while. :rolleyes:

I enjoy looking at the groups .
Hard for me to visualize 3.6 inches of vertical, 1.7 inches of horizontal . :D
Sometimes a couple of fliers can be the difference between 3.6” of vertical and 2” .
Someday I’m going to start back going to the range and I’ll shoot a couple targets for this .

The Firearm Hunters will be all over the range until the firearms deer season starts next weekend. Got to sight those rifles in that haven’t been shot since last season :eek: .

Marlin 60 off of front bag
Winchester M-22, old stock before WINCHESTER went down the tubes
75 degrees light wind from 5:00

The rounds out of the black are on me. I was rushing to complete before the cease fire was called.
Next time I will try different brands of bulk

Mals, l still use a 1974 model 60. 17 shot tube.
My favorite squirrel rifle. Load it in the morning, hunt all week. ;)

Out to 25 yards it fills the game bag. :t
Nobody is taking 100 yard shots in the thick North Florida underbrush.
Usually 15 to 20 yards...at that range ya' don't need match ammo. :D

Someday, Bill, I'll have a similar setup....I hope. :D

Meanwhile, I entertained myself finishing off some leftovers.

Federal 36 gr cphp 22lr rated 1260 fps



CZ 455 Varmint, Lilja barrel, Sinclair bipod, Mueller 8-32X 44 target reticle



And the results

 
#51 · (Edited)
SK Magazine 40 grain 22lr rated 1073 fps
Goober lube in a can, bring paper towels to degrease y'er fingers. ;)



Excess bullet material crimped down past the case mouth onto the brass,
irregular seating, asymmetric drive bands...yep, it's bulk ammo.
Used a CCI box to hold 50 to keep track and keep my fingers clean.



CZ 455 Varmint Lilja, Sinclair bipod



Look at the vertical spread...some serious mv differences in those cartridges.

 
#54 · (Edited)
Well Bill, I'm sitting down here bored, started raining and last shooter left. Wanted to shoot something but no spotter/witness/scorekeeper to do my timed event entry. Saw your post and since the Martini is sitting here decided to try 25 at the 8" circle at 197. With the rain its a tad above center but decided to go for it.

I'd say 4" vertical but the target wasn't perfectly clear every shot and I've done better but wanted to pass it along. I can live with it though for rain and slight haze and 66 year old eyes after spotting for 4 days.

Wind was from my 4, wall and RSO office on that side.
That put me in the wind shadow along that side of the range Kirby.
Minimal wind effects. What ye'r seeing is cartridge quality differences.
Neither is great, but the SK had serious problems with mv spread.
The supersonic transition has minimal effect on the 22lr,
when compared to the effects created by primer/powder variations
and bullet deformities.


...except for the three fliers...:D

There are no exceptions in my world K.
It's the results from all 50 shots, not just those that make me look good. ;)

Top...how do you compensate for rain drift?
Droplet size or the number of drops intercepted per linear yard?
Just thinking...;)

Wind today so played .243 at 200 yard, had to fire form some cases necked down from .308 NATO brass. 10 gusting to 23mph has so little effect with 100gr bt hp’s compared to .22, spoiled with 2-1/4-2-1/2” groups.

If the wind ever settles remains Eley Match to be tested through both Martini’s in side by side comparison. Early MK II has a whole lot less rounds through it then the MK V perhaps a million more as a club rifle.

Good shooting fellas!

It's a start CM. We will see what happens as we work our way up the quality levels.
Maybe we can get some others willing to invest their time and one box of cartridges.
This would make a useful rimfire ammo reference, where the results aren't cherry picked.
Everything from Aguila to X-Act.

I know this is the 50 at 200 yards thread but personally I've found that 25 rounds is more than enough usually to get the results I'm looking for. This Biathlon is by far the most consistent ammo we've seen for our longer range matches. The group down South that is stretching it out to 400 yards or so stumbled on it first. Scores at my matches have really gone up and spotting all the shooters I've seen a big difference in group sizes and smaller targets hit.

Wind affected by rain? Have shot in some really heavy rains at the 1000 yard matches and it still doesn't seem affect it. Humidity and other factors mess with it more. Hardest part is keeping a clean picture of the target and trying to hold for slight wind changes peering thru the peeps. But it's sure fun and what I've shot about all year at my rimfire matches.

I hear ya' Top.
50 at 100, 50 at 200, same idea, different distances.
It's about ammo quality, wind and the ability to maintain concentration.
Most benchrest matches run two 25 shot targets in succession.
That's 50 shots to determine the best results.
Same routine taking place here, just all at a single aimpoint.
How tight can the results be when you have to count every shot?
Not when you cherry pick only those that make you happy.
Sure cuts down on random acts of accuracy, eh? :D
