- CZ 457 LRP - 100 yards - SK Long Range Match - IBI Barrel
In this video I will test SK Longe Range Match 22 long rifle rimfire ammunition to see how well this highly regarded ammo performs in my CZ 457 LRP. I have installed an Olympic contoured barrel from IBI as well as a flat blade Timney CZ 457 precision Trigger.
this video is shot at 100 yards to test the ammo for repeatability and accuracy!
Hope you enjoy the testing and DON'T FORGET TO SUBSCRIBE! , COMMENT, AND LIKE! the video.
There will be new videos releasing every Sunday morning at 9 am!
Question: Since wind indeed will effect placement and size of grouping why not adjust the sight to counter it? After all, isn’t the idea with these .22 rifles to develop marksmanship? And isn’t marksmanship mostly about correctly countering for wind? As an NRA governed long range competition competitor I find that it’s the ability to counter wind correctly that separates winners from losers and since the .22 LR standard velocity cartridge has an MOA wind constant of 10 at 100 yards the wind adjustment formula for this cartridge at 100 yards is super simple and can be done from in the head math in a heartbeat, so why not just do it? The formula is yards divided by 100 times wind value in mph divided by constant of 10. So, let’s say you have a full value 10 mph wind then the formula looks like this: 100 yards divided by 100 equals 1 times 10 mph wind equals 10 divided by constant of 10 equals 1 MOA of favor. Pretty easy and for sure will ALWAYS improve grouping size and placement. The bottom line is use the .22 rimfire trainer to develop marksmanship including knowledge for what to do about the wind because having the wind disturb performance does not go well when the whole idea is to hit where aimed.
Yes I agree. Thanks so much for sharing this information it’s really appreciated and I will definitely start practicing this. But basically in this video I was just maintaining a constant aim point to see how the ammo performs. But yes 100 % on the idea of trying to read and adjust for wind to make the poa = poi but again thanks for this post. Cheers
Thanks for the heads-up on this ammo. As a result of watching this, I bought some. I am in the UK. I used my old1957 BRNO Mod 2 and at 100 yds on an ouside range, got consistent 1" groups. My friend, using a 1970s Anschutz 54 match target rifle got a 1/4" group. This is clas ammunition, especially for the price of £8.20p over here.
That’s awesome definitely anything moa or less is great
Cheers for the video, great groups.
Thanks! Glad you enjoyed it cheers!🍻
Very impressive shooting from the prone position. My old neck won’t let me do that anymore.
Thank you sir
Well is pretty safe to say that ibi barrel likes SK long-range good shooting
That and tenex are awesome in this barrel
Man, liking that
barrel, not to mention your shooting skills. Go job. Yes! See you next Sunday.
Thanks so much I’ll keep the videos coming and if I get extra time I’ll have video’s Wednesday also! Stand by!
Nice shooting mate think that SK long-range match is one of the best iv come across especially at the price
It's half the cost of tenx R 50 and Midas plus in the UK.
Ya same here and easier to find also
Got the same gun ,it extracts the casings but drops all of them at the last shot -frustrating
Just sighted in a new lot of eley match and it did 0.33moa at 97 meters 5 round group.
Was gonna shoot with the sk lrm, but the lot I had performed horribly, about 2moa 10 round groups. Usually that round has worked pretty consistant.
.33 is awesome at 97 meters! Very impressive
@@BROTUNED Yes, best 22lr group so far and performing lot as well. Not sure if im more impressed with the 97 meter group or that managed to shoot a 0.84moa 5 shot group off of a prs barricade at 200 meters. Sure sample size is small, but have to reserve ammo since only bought 3 boxes and the comp will require 2 boxes
Seems like I forgot in my original comment that have a competition coming and was gonna shoot the sk lrm at the comp.
Nice shoot my bro ❤
Shooting pretty good!
Now that you took a chrony break you can go down there and put the caldwell on target so we can see how much energy is left @100 haha
I could definitely try that fire sure! The accuracy is there so don’t really have to worry about shooting the chrony
Awesome just friggin awesome 👍👍👍👍
Thanks Vinny!
Hey man, is it the stock trigger or did you alter it by Timney, Yodave or something else?
Greetz
I at first modified it with a pen spring which made it a lot lighter. Then because I really appreciate nice triggers I purchased a timney replacement trigger and haven’t looked back
Nice! I had about the same results with SK Pistol Match Special out of my CZ 457. I made a feeble attempt at a video, I'll add a link to it if you want to see.😄 I wasn't dealing with the wind like you were.
Yes definitely I’ll watch it!
@@BROTUNED Get your popcorn ready 😄 It's 30 seconds long. 8x speed ua-cam.com/video/a2w9CXJIm1Y/v-deo.html
I subscribed! That 4th group was great!
I have very similar groups with Sk red at 100yrds with the stock barrel
That’s perfect! Definitely can’t complain about that.
Excellent for sure with the conditions. Time to think bolt shim now. Lol Don't know if it's the little extra squeeze on the back of the rim but most of my aggravating tiny flyers have ceased to appear way less often
In keeping with The Wheels comment, I too weigh sort all my SK.
Makes a Hella difference in my 3 rifles. In fact my Kidd Supergrade has tallied a few scary groups under .100 Scary because I've been using these same eyes for nearly 77 years. Lol Thought I might be missing the entire target but my step-son did it too.
That’s amazing I’ll have to try it! What kind of weight differences am I looking for?
I still have to try the shims
Rifle would shoot a lot better if you got rid of that ridiculous rear rest you have to hug & continually adjust !! Get yourself a decent one , try a Protector 13A & you will see your groups come down to under a 1/4 inch. Also look at a Farley front rest. Rifle has everything going for it especially the IBI barrel. Also give Eley Match ammo a try, much better than SK.
Cheers
So how bad was the factory barrel to make you want to slap another one on?
It wasn’t bad but I have never tried an aftermarket barrel and this was my opportunity to be able to easily do it with no specialty tools and without breaking the bank. The factory barrel is great but the ibi is way better
Seems like it's working well for you! I'll suggest to you something that was said to me when I fist started in this. Aim small miss small. Instead of aiming dead center of a 1"x1" Square try aiming at one of the corners of the red squares.
Yes agree 100 % I’ll start doing that for sure
Thanks so much for the advice
Excellente Bro 👍🏻👍🏻👍🏻✌🏻🎯
Thanks
LUV SKLRM MYSELF GR8 VIDS BRO😎😎
Thanks
Run Some Eley match mate. ;)
have you done a review with sk yellow? I have the same rifle they are heavy but i put it on a tripod shoot rabbits all day
I haven’t seen any yet but I’ll let an eye out for them for sure.
what barrel length and twist?
Barrel length is 22” and it’s a 1:16 right hand twist
Great shooting brother! Where did you get the rear bag? And what it called?
Beagleman
I made my own I’m cheap so I learn to do it myself so I made a bunch of different shapes with material and a sewing machine then fill with rice and this shape seems to work best for me so far
I can make more if you want one
@@BROTUNED sure would like to have one will pay you good for one just let me know how much you need and I will send you the money you could probably sell those I have ordered two and these were both little things not worth it let me know how much I Wllsend it to you.
Beagleman
Did you want them full of rice or just the bag and you could fill it because I would imagine the shipping would be pretty steep with the rice in it.
Have you tried Eley sport and club in the new barrel?
No I haven’t as of yet but I will do it soon for you. I wasn’t sure if anyone was interested in seeing it.
@@BROTUNED thanks, I’ve become a big fan of Eley sport recently, I bought a few boxes of club as well, I didn’t think they were much better than sport at 50 but there might be a different at 100.
It crazy how things can change at 100 yards 22lr is a completely different animal
Tough shooting at 100

What chamber does the barrel have? What is the twist rate?
Hi there Timothy! I’m not exactly sure what chamber is cut in the barrel. Maybe google can help find that out, but the twist is a regular 1:16 rht. I’m been tempted to test a 1:14 to see what it can do but that’s still on the table. Also I’d like to try a longer 24 or 26” barrel to see if that makes a difference
@@BROTUNED yours is a 20" correct? I am kicking around the 24" right now. Havent decided yet.
Iseeyou also fill your rear bag with RICE !!! Wait until your bag gets even slightly damp & you will find the RICEwill start to shoot with green shoots all over the bag.--- AMATEURS !!
So why waste your time and ammo when conditions are not optional?? Information is of no use if the wind is moving the group? I just got back from the range and shot my CZ at 100 yards..10 shot groups. Eley match. Averaging .6". This was under good wind conditions (daisy wheel wind flags) when the wind started to move the flags and my group started opening up? I quit! No sense wasting good ammo unless....you are practicing shooting for score in the wind and are holding off.
I see too many you tube videos with people shooting/testing under windy conditions and then, without some decent wind flags. It looks like you shoot from behind your house so you should be able to pick and choose when you test😮
Yes this is true but I try to do it in the best conditions possible but I also work 48 hours a week and can’t always shoot when it’s calm. I wish I could but at best I can shoot in perfect conditions maybe 1 day a month. But I hear you loud and clear Richard. On your .6” at 100 yards that’s a great group I have been there before and I was completely impressed that a rimfire rifle could do that. Even though the price is basically equivalent to shooting 223/556 if not more ha ha. Most of the time the only time it’s calm is super early morning before the sun comes up or after the sun goes down and in Canada it’s illegal to shoot at these times of the day. It’s just what I have to deal with. I find at 50 yards the wind doesn’t really make much of a difference but at 100 there is a shift for sure. Anyway thanks for commenting your concerns about the wind and I’ll definitely try to do my best to shoot these ammo tests in low wind situations. Cheers sir!
What the fook is going, on you have a beaut rifle and put another barrel on it WHY!
These test are not inclusive of the rifle in original condition.
It's not a CZ 457 any more, if you change the barrel my friend, no it's not a CZ.
I just don't get it at all, just wasted my time here!
Sorry to hear that
