Discussion thread - 2024 - 100 yard .22LR challenge

[horseman2]

For those with rifles that can be shot from either side it is interesting to see where the groups go.
I tried this last week and was pleased that I could probably be competitive had the change been required.
MEROH's situation is an example . . . Necessity is the mother of invention might apply.
Many left handed shooters learned on a mentor's right handed rifle and never switched to a left handed rifle.
There is limited choice in rifles produced for left handed shooters and some just do not exist.

just posted a couple more targets in the other thread shot with my Oryx Supermatch; this time, because of the rapidly advancing cataract in my right eye, it was either shoot left handed or quit. I was quite happy with the results shooting weak eye and left handed on the trigger. Much less of a handicap that I had thought. In pistol I shoot right handed, but with the left eye and do OK with that as well.

It may not be a regular experience to have genuine "flyers" with match ammo at 100 yards because groups easily vary in size and it's hard to always know what's in the normal range of a group at that distance.

This morning it was as calm a morning as could be imagined. I shot two lots of new-to-Canada 2024-manufactured Lapua Midas. I've been testing it this week, today with the third rifle. While the results so far have been unremarkable, today's had some groups that left me thinking about flyers at 100.





The top two were unaffected by wind. There was none that could be detected with the flags. The bottom two seem as candidates for errant shots that can be explained by MV variation. But in neither case were the outliers either the fastest or slowest rounds in the groups.

I did get one group without an outlier.

The thing I like about 22 is you can tell when a flier is going to happen with these young eyes. I know where the reticle was when the trigger broke, and I can hear and see the bullet impact elsewhere. Those groups are insane! Think of how many people and rifles struggle to even get that at 50y.

Very nice... should serve you well.

I'll have to enter again with my CZ457 chassis build now that I've got the IBI barrel on it. My CZ 457 American got the old varmint barrel used in previous entries... so I now have a very accurate hunting rifle for grouse this fall.

Please, do I understand you fit a varmint barrel - thicker than the original - on a CZ 457 American ?

I started with a CZ457 Varmint and then replaced the barrel with an IBI barrel

Bought a CZ457 American, and replaced the pencil barrel with the Varmint barrel, and swapped the composite American stock for the Varmint walnut one. So it is almost everything from the original Varmint rifle, except the action from the American.

The actions are identical and will take any 457 barrel. If you plan on building out a CZ457 with a new barrel and such, just get the cheapest 457 you can find, as the action is what you're after and there is no difference between any of the models for that part.

Since I've recently picked up a lighter gun for grouse (Zephyr II), I'm not sure what I'll be doing with the Varmint now. Don't have a use case at the moment.

 

[DanRR]

Thanks a lot barthammer....

Bought a CZ457 American, and replaced the pencil barrel with the Varmint barrel,

I should have asked : I have a CZ-457 At-One.
Can I buy a Canadian Edition stock and install the varmint barrel of the At-One ?
I believe the answer is "no", but , being new in the CZ-22lr realm, I prefer to rely on the answer of a knowledgeable shooter.

Thank you.

That's a slightly tougher question... I'm not sure if the Canadian stock for a pencil barrel has the same clearance for the barrel as a varmint stock. My american was a synthetic stock, which definitely has the clearance to accept a varmint barrel but I have no idea if that also applies to the american/canadian wood stock.

There are a bunch of 457 shooters at our monthly matches, and I think at least one of them has put an IBI (similar profile to varmint) barrel into a wood stocked 457. I'll see if I can find out for you this weekend.

 

[grauhanen]

Today I continued testing the recently arrived 2024 manufactured Midas.

I achieved a first, something I have never been able to do over the years. Ten consecutive sub-1" groups.

Along the way I got my best group of the season. It was under .500"ctc.

You can install a varmint profile barrel in a Canadian edition stock, though you'll likely have to relieve the barrel channel of the stock a little bit. This can be done with some sandpaper attached to a long socket of the appropriate size. Work it until you can slip a sheet of card stock under the barrel all the way up to the receiver with the barreled action installed and torqued down. Be sure to re-seal the exposed wood with some clear polyurethane or finish of your choice after.

Congrats on the achievement, grauhanen. I'm sure that must have been very satisfying.

Thanks a lot Leuchtkafer and barthammer.

Unfortunately there was not a CZ 457 set up at the shoot yesterday that showed what I wanted to see to answer this definitively for you

I would agree to err on the side that you may need to open up the relief a bit on an american/canadian wood stock to fit a varmint profile barrell

Nicely done grauhanen... 1/2" groups at 100y are rare but feel damn good when they happen!

With the snow going earlier than usual across many parts of Canada, the 2024 shooting season is underway for many rimfire shooters. I visited my club's range two days ago for the first time this year after its access road, which remains unplowed in the winter, was declared sufficiently dry and fit for vehicular traffic by the club bosses. It was cold and windy so results were poor. But being able to get back to shooting was good.

As in the last couple of years, I wish to invite .22LR shooters to make an entry in the "100 Yard .22LR Challenge". This is not a contest between shooters, but rather a challenge for each shooter himself. How well can you do? Can you do better?

The rules and requirements are described in the first post in the thread itself. The challenge thread is here https://www.canadiangunnutz.com/forum/showthread.php/2297200-100-Yard-22LR-Challenge

Basically the challenge is to shoot at 100 yards/meters three ten-shot groups at the required target. Measure the center-to-center group sizes and calculate the average. This is a challenge for each shooter. Improved results are welcome.

The target is the same for everyone. It can be found in links in the instructions and below. I will email a pdf of the target to shooters requesting it. The target must be printed on 65 lb card stock.

The link immediately below should show the target.

https://drive.google.com/file/d/1PCc_bNidaPtRd6ywdP4dISZhLMYYE1-g/view

I haven't posted any Challenge results since 2021, when the Challenge was developed and begun by CGN member horseman2. I've acquired a couple of rifles since then, so if no one objects I may post an entry or two if I find that any of those rifles produce good results.

Observe the rules and be safe at all times.

The 100 Yard .22LR Challenge thread is for entries/results only. PLEASE DON'T COMMENT IN THE CHALLENGE THREAD ITSELF.

If you have questions or comments, please post them in this thread.

Will definitely give this a go, my son, daughter and I just got back into shooting last weekend after 8 years of no shooting . My 15yr old daughter was the best outta the three of us lol 100 yards and she hit the 8in gong with a marlin model 60 on average 8/10 shots. Will print out the targets and post the results. Always looking to improve

I was tuner testing at 100 again today and shot the ten-shot group shown below. While a single group doesn't necessarily tell much about the big picture, it feels satisfying to get them now and then. The caliper shows the outside dimensions.

Good afternoon barthammer,
I had a friend of mine take some measurements from a CZ-457 American and the swap of barrels with my At-One seems feasible.
I then wrote to Tesro and asked if it was possible for them to send me a stock with the wood grain without streaks.
They then sent me this morning the photos of the four stocks they have .
I choose this one.
+1 for Tesro.
Thanks,
Dan

Today I used a rifle I have used only for the third time this year. I was pleasantly surprised to see a couple of sub-.500" ten shot 100 yard groups.
These don't happen very often.

The caliper shows the outside-to-outside dimensions.

It would be great if you mentioned what rifle and ammo combination is used to get these incredible results

On Sunday, Sept. 29, the rifle I used to achieve the .616" outside dimension group was my Anschutz 1907. The ammo was a better-than-average lot of Center X. I hadn't shot much of that ammo prior to that. I shot fifteen ten-shot groups and the average was 0.915".

Yesterday's results were shot with my Anschutz 1913 and the ammo was Midas. I shot ten ten-shot groups that averaged under 0.850".

I used different Starik tuners with both rifles but it's not clear that they are responsible for the results. I say that because, except for the sub-.500" group results occurring within a few days of each other, the averages are quite similar to results previously obtained without using a tuner.

 

[EugeneM]

grauhanen, are Anschutz 1907 and 1913 both with 54 action? I am not too familiar with the Anschutz line, and their model numbers are very confusing.

Anschutz model designation can get a bit confusing. Yes, they are both 54 match single shot actions. These are a little different from the sporter 54 repeaters.

The difference between the 1907 and 1913 is the barrel. The xx07 barrels are 660mm (about 26") long and 22mm (0.866") in diameter. The xx13 (and xx11) barrels are longer and heavier (690mm in length and 24mm in diameter). All Anschutz xx07 and xx13 models, from the 1407/1413 to the 2007/2013 have these barrels (except for one model of the 20xx that has a 500mm barrel).

 

[grauhanen]

Today I shot ten ten-shot groups at 100 yards that were all under 1". This was only the third time ever that I have done this. It's harder to do that than shooting a target with a three group average under 0.700".
