100 Yard .22LR Challenge


redryder, while you might find the post above to be a belly shaker, you should be aware that readers have been asked not to post anything other than qualifying entries on this thread. In fact, only last week, after you posted "ffs" in reply to such a reminder, I asked you not to post unnecessarily. Thankfully, these posts were removed by a moderator.

Now you do it again. Please respect this thread. I hope this post and yours above are again removed.
 
Since this is more of a personal challenge than a competition against others.

So here is a windy group. AVG 1.78 beating previous record.

Anschutz 64 Silhouette, Eley Sport Ammo, Tasco 8-32x44 ( 20X ), Vera Pod, rear rest.

Then knowing I can do better.

Anschutz 64 Silhouette, Eley Sport Ammo, Tasco 8-32x44 ( 20X ), Vera Pod, rear rest.

I'm still getting used to the lighter trigger and the gun. I was figuring how much pressure to put on the gun, so why the groups were improving as I went on.

AVG 1.4805

I am going to make one and final entry for this competition. Winter is coming, I am moving to indoor 25meter range with target/iron sights.

I guess I got lucky today. The group is pretty consistent and surprisingly good. Literally no wind, and temp was about 15C.
Rangefinder shows 106.4 yards.

Rifle is Anschutz 1761 MPR sitting on a Harris bipod and a caldwell rear rest bag. Scope is Leica Amplus6 3-18x44mm.
Ammo is SK Biathlon Sport.

Average = 0.747

My submission from today.
20” CZ 457 At-One stock except for a YoDave trigger spring and an Area 419 bolt handle.
Scope is a Bushnell Elite Tactical 4.5-30x50
100y prone.
Couldn’t use the covered shooting benches due to tens of thousands of lady bugs.
Normally I shoot this rifle with the stock fully collapsed but I don’t have enough eye relief with this scope.
I may need to juggle scopes around a bit to make this work better.
1.941, 1.177, 0.841 Average=1.319” with SK Long Range Match


Shot it with both SK LR Match and Lapua Center-X.
I literally had 30 rounds of each which is why I didn’t take any sighters.
The shot in the 8 ring on both upper right targets were my sighters.
I’ll be more prepared next time.

Fall has come and winter rains are here so this is the last good group of the year.
Our 100/200 Metre Rimfire is an all year event and the wood burning stove is a welcome relief.
Thank you to all the participants and to the co-ordinator, Mr. Rauhanen for running the event and keeping everyone in line.
This was my best group at our October 16th shoot, shot with the Remington 40XB.

 




Here's my 3 groups shot today at 100m.
Anschultz 1416 hb 18"
Cheap scope Buckner 4-12x
SK long range ammo.
Groups
1.485"
1.076"
1.250"
Average: 1.270"
Quite happy with that result. Also shot some 10 shot groups at 200m all around 2", 2.5".

New entry: Shot with aperture sights!

I am on an aperture sights kick these days, (new discipline for me), and was wondering how I could shoot this challenge using the official target. The official target is white on white, so there is not an aiming bull that I could see at 100m with apertures. I came up with a novel approach that I hope the Match Judge will accept as a valid method: I marked the center of the target and taped it to the back of a Cibles standard 100m aperture/irons target bull (8 inch aiming bull). I calculated elevation and windage clicks needed to move the 10-shot groups into each of the three white targets.

My calculations were slightly off for windage clicks, or the wind pushed the groups, but I managed to keep them on the official target taped behind the aiming bull.
Today's (March 4) conditions: Warm, about +2C. Light winds (weather channel said 6-8 km/hr with gusts to 10-15 km/hr, but actual range winds unknown, and the flags were moving).

Distance: 100m.

Indoor/outdoor range: bench in heated shooting house, rifle shooting through window port with end of barrel outside. This makes for interesting and unknown effects of barrel differential temperature. Ammo temperature is approximately indoor ambient, but it cools at the bench due to the cold air coming through the window port.

Rifle: Anschutz 1907

Anschutz aperture sights: Rear aperture sight iris set today at 1.3. Front aperture iris set today at 3.2.

Ammo: SK Biathlon Sport

Photo #1 shows the bench set-up:

Biologist_Mar_4_2023_100m_Bench.jpg

Photo #2 shows the post-shot official target taped onto the back of the Cibles 100m aiming bull target. The cross-hair marks find the center of both targets, which are then used to line them up accurately for calculating elevation and windage clicks to space the groups into the appropriate official target area:

Back_of_Target.jpg

Photo #3 shows the shot targets peeled apart, with the measurements. My windage clicks ended up being a tad generous for the right side targets, but all rounds stayed on the paper:

Targets_Peeled_Apart.jpg

Measurements were done on the top target because these had the accurate carbon ring around the holes. I checked the measurements on the underneath official target, and it is interesting that you can see a deformed paper ring around the hole, approximating the carbon ring. But for consistency I measured off the top target carbon rings.

Photo #4: Shows the same measurements on the official target:

Results: Not great, but I have a starter baseline now to challenge for improvement.
Group 1 = 1.560"
Group 2 = 1.713"
Group 3 = 1.379"

Average = 1.551"

Photo #5 Largest group 1.713".

Nice to see that it can be done with aperture sights. Let me suggest, you'd enjoy using an Anschutz competition sling, as an alternative to the lead sled. I mean the kind that tightens around your bicep, loops over your forearm, and attaches to the rail under the fore end of the rifle. It does a lot to stabilize the rifle. I have this setup on my similar Anschutz rifle.

Please post only valid targets and related information in this thread. This is noted in the first post and elsewhere in the thread. Comments, suggestions, and extraneous information should be sent by PM to anyone concerned.

New entry shot May 31, 2023.

Distance = 100m

Wind conditions today: Tricky with gusts and directional switches. Kestrel shows max gusts to 3.2 m/s and average 1.6 m/s. Three flags downrange for wind reading. For detailed discussion on the wind effect on results, see the Discussion at the bottom of the post.

Max_Ave_Wind_Speed_mps.jpg

Bench set-up:

Rifle: Anschutz 1907 (54 action, 26 inch barrel, 4 oz trigger).
Scope: Sightron 45 x 45, target dot reticle.

This 100m range shoots at a downwards angle. That Caldwell front rest does not get low enough with the rear Protektor bag as-is. Therefore, the box shim under the rear bag is used to lift it high enough in order to point the barrel downwards.

Gear_Set-up.jpg

Today's ammo: Eley Team.
This lot of Eley Team shoots very well in my rifle...BUT...on average there seems to be about 1 round per 50 which is a crazy flier. Today the 30 rounds of this ammo shot "honestly" with no crazy fliers. The ES in the groups was due to my errors. See Discussion for details.

Results:
Target 1 = 1.084"
Target 2 = 1.322"
Target 3 = 1.074"
Average = 1.160"

Discussion:

On practice targets I had zero'd on the center X. Predominant wind is from the right. On the targets here you can see the wind push to the left. When the wind was at its lowest, I held on the center X. When the wind was stronger from the right I held right and did OK. When the wind switched to come from other directions I waited.

On target 3 the waterline looks quite good, but that far left hit was my fault for a bad wind call. I held right but not far enough for what the flag was showing, and it opened the group. That bad wind call cost me an under 1 inch group.

I had some vertical on targets 1 and 2 which I think was my fault. On practice targets today shot before this one, my normal free recoil technique was not working for some reason. I was all over the place. For this target I switched to a controlled recoil method with a firm shoulder pressure, medium cheek pressure, and a strong grip on the pistol grip. The benefit of the strong grip is that it prevents lateral wobble, as long as the recoil force is perfectly straight back. But the danger of the firm grip is that I can sometimes pull down on the grip instead of letting it recoil perfectly backwards, which causes the muzzle to tilt up during recoil, which then causes vertical. I think that is what happened on targets 1 and 2.

Overall, not bad for the conditions. The ammo shot well. I need more practice with the controlled recoil method.
