With a new entry in the 100 Yard .22LR Challenge, it seems like a good time to have a thread for discussing the topic and entries made in the Challenge.

Barthammer posted a good 100 yard target today shot with his IBI barreled CZ 457. In his post he made the observation shown below.

Trying out some different ammo and RWS Special Match showing some promise.... depending on the day. Did not perform for me on game day, but that's probably the shooter!

The same ammo didn't perform one day at 100, but it surely did with the target posted today.

This raises a question or two:

If all else is the same, is it the shooter or is it the ammo? Wind aside, while we may have .22LR ammo that regularly does well at 50 yards, do we have ammo that's consistent enough to regularly do well at 100?
 
I think it gives reason to go out and shoot.
22 especially. Going without reason can sometimes feel quite monotonous imo

Having a fun challenge anyone and everyone can take part in is fun. Seeing the different rifles and ammunitions used too.

It’s a very very level playing field for all skill levels and budgets.
 
lot number is one thing
matching a lot number to temperature and humidiy is yet another thing

you still take the laces out of your new shoes and then wonder why your shoes won't stay on, yet for years, we tried to teach you how to tie your laces, and yet here we go again, stick to flip flops
 
I really like to hear what everyone is doing and seeing! I am waiting on the snow (range has been blown full, 6-7 feet, not even kidding) to go so I can get back in the game. I think I have my 455 oryx pretty much complete, I have recently added a new take off 20" CZUB Varmint barrel, was able to find a correct, new CZ "Kompenzator" for it. On the indoor short range, it is showing great potential compared to the original "Supermatch" barrel. I am getting Itchy. LOL

Does this mean that ammo lots that shoot well when it's warm will not when it's cool?

Does it mean that lots that shoot when it's humid will not when it's dry?

That's what we've been trying to tell you for decades, try it sometime

With regard to .22LR, I have shot the same lots when it's warm (20 degrees Celsius or more) and when it's cool (minus 5 to plus 5 Celsius) and temps in between. It's quite likely that humidity was different at least on some occasions.

Wind aside, results have been quite similar with no correlation to temperature differences. In short I haven't seen differences because of temperature. And I've never seen one lot shoot when it's warm but not shoot when it's cool (or vice versa).

Of course my experience is not conclusive. Definitive information is almost always in short supply with regard to rimfire. The trouble is that there's no body of tested evidence on the topic of temps affecting lot performance.

For readers in general, a glimpse into how temps possibly affect accuracy performance see post #12 in the link that follows. (It doesn't in this study.) https://www.rimfireaccuracy.com/Forum/index.php?threads/cold-weather-ammo.27105/

When it comes to shooting at 100 yards, again wind aside, it's possible that the accuracy performance of .22LR ammo owes less to temperature and humidity differences than to something else.
 
Just a heads up for you .22LR target guys; MILCUN hosts a 22 M-Class shoot with practices this season. 10 shot groups from 50 to 300 meters in prone position. The class is unrestricted so long as it's .22 LR. Score is out of 400 points. The two top shooters scored 399. Winner determined by bullseyes.
 
I think lot matching is kinda stupid, especially if you aren't being paid for this.

1) you can't re-shoot something you already fired
2) the lot you got is probably sold by the time you get it, test it, and go back for more
3) What are you gonna do when you're out of that Lot?
4) You just proved that there will be other lots that do work for you
5) with a 22 at 100 yards you can already tell where the impact will be before you even hear it when your scope is set up right

this of course is just my opinion, which of course is right.
 
if you can't see the difference weather makes to your ammo, you're either, not good enough, or your expectations of accuracy are far lower then ours. when you're on a firing line of 20 or so good shooters, you can see the corrolation of overall score both drop across the firing line or increase given by the enviromental conditions, be it 50 yard score or 100 yard score matches, shooting on your own time in a relaxed enviroment when you're mentally ready to shoot is less likely to mimic the results of people who are forced to shoot on a particular day in particular conditions.

and again, as if it's never been said enough in the past, air temp drops, ammo will slow down, air temp increases, ammo will shoot faster, wet air is slipperier then dry air and thus has less drag on the bullet, you may not see the effects of this on an f-class target, but you will on a benchrest target.

I have had case lots of CCI SV that would shoot just under 3 inches at 100 meters in the summer that also shot inch and a quarter in sub zero temperates and vice versa, for the average 2 brick a year guys, you're never going to see the results of us 6-8 case a year guys that put in the effort on the range to learn for ourselves, can we duplicate it over and over, bet yer azz, it's part of the information gathering we do in the field rather then relying on false information on the internet and universiy grads that say according to computer graphs what we're experiencing is impossible, it's more credable to have someone posting pictures and asking questions then it is to have some keyboard warrior just drafting up hypothetical questions from the comfort of their couch

but hey, anyone with a factory tikka and a bushnell scope are pros? right?

maybe enlighten the group on your years of shooting experience and accomplishments so we know why your "opinion" must be right

Glenn doesnt. Its a rhetorical question,he only has the right answer and nobody else. Turns into the same dhit everytime. Too many small variables that adds up. You cannot repeat the same conditions each time and you will get variables.


And #### like this is why nobody does the challenges anymore. I find rimfire people have an expectation past what the ammo can do. I got told my Annie 64 a POS and I'll never do good. I must need this. Sorry I'm not an elitist prick that has to #### on everything and discourage others from getting into it.

I think this challenge isn't what it's orginally decided for. Nobody new is trying because if you don't shoot 1 inch or in the target elitist #### on you. Pepple forget to have fun.

But if you want to sound like an ass and discourage others, keep doing it.


I can goto 2 different ranges and have different results only a day apart, using the same ammo.
 
Read an article on Rimfire Central where a shooter tested ammunition based on atmospheric density.
At a shoot he had four lots tested to various AD's, and as conditions changed so did the ammunition of choice.
I can't keep track of one AD and one lot of ammo.
However, on a day when my ammunition performs admirably it was because the AD was right for that lot. LOL

He definitely seems to adjust the rules on the fly to make sure people are outside of the parameters as much as possible.
Way to serious for "not a competition" only "shooting against yourself"
I paid for a bunch of in spec targets printed and sold them to someone more willing to participate before even trying one.

And here I am passing mapleseed. Not only did I pass on all 3 attempts, I was also the only person attending who passed. AFAIR my worst score was 225/250. Im also only wearing a $25 Crappy tire sweater. Too bad i didn't get some Sitka - imagine how much I'd know then!

Guess what I used?




a $199 chinese rifle with a $199 Vortex chinese scope shooting CCI SV in a Home Hardware PINE stock that I rattle canned a week before the event. It was still off-gassing the day of the event. Every animal I gotten was shot through the heart while being offhand - last one was 180 yards.

Im not good at a lot of things, but I have a natural knack for marksmenship, calf raises, sarcasm, and putting people like you in your place ;)

Of course, that's just my opinion. (which you didnt understand the first time)

✔ + Use of a Cortina Tuner - helps with different ammo lots types etc yeah 😏
 
Great, now do a Mapleseed with bolt action and open sights and also get the high score of the group ;)

Temperature can certainly affect performance of the ammo, when ignition consistently fails with a particular lot, the scores become quite poor indeed :LOL:

I don't think he was calling you out near as much as he was calling Glenn out, and in all fairness, mapleseed is shot at 25 yards, the target sizes in ORPS and CRPS are so large that anyone shooting any ammo stands a good chance of acing all three, they are designed around the shooter, not so much the equipment, now take that out to 50 and 100 yards or meters and run it in a benchrest match and you will begin to see things differently. Great shooting on both accomplishments, sincerely, but it's kind of cross contamination of precision and practical shooting, and there is nothing precision about practical shooting, they are as different as a clip and a magazine
