This is the first video I’ve watched on this channel. It could have been 2 hours long and it would have only made me happier. The amount of effort to make this video is not lost on me so a very sincere thank you! You’ve got a new subscriber from up here in Alberta, Canada.

I was at the range this morning at sunrise, shooting my custom Ruger 10/22. The redbirds were chirping in the trees behind me. I enjoy your videos, and I like that you appreciate the sounds of nature, and the smell of gunpowder. Life is beautiful.

Thank You, It is so enjoyable to watch someone that never acts out his ego. Also can shoot and tells the real story

I really enjoy your 22cal videos. Such a great wealth of information. Thank you so much for putting in all this time and effort for the rest of us to learn from.

Interesting results with that ammo and tuner . Great fun once again to watch, and a great last group.👍

Very educational. I really enjoy this kind of testing. Thanks for putting in the time to do this. Not to mention the ammo!

Excellent, detailed video. Thanks for your hard work making this useful for all!

I‘m impressed….! 😳 Thank you for this great video.

You are a pleasure to watch Sir ! Thank you for your videos.

Great stuff! Love the 22 LR vids. Keep em coming. Thanks

I enjoy the videos. My dad was in the Marines too. He was on Guam with the Raiders early on. Thanks

You look comfortable! And that helps when shooting for sure. Another great video, thanks.

Thank you for this video. I appreciate all the ammo I didn't have to burn to learn a bit more about the Harrell Tuner.

Fantastic video!

Thanks for the video. I know you kept saying it was longer than you’d like. I’d rather see the struggles you had so when I’m at the range having the same struggles I know it’s all apart of the process.

Solid video, I’m on the path of research and I appreciate your sharing this us.

You sure have one of the nicest 22 rifle collections and you make some great videos

Tks again brother, you have inspired me to shoot more 22lr long range. 200-225 yards

very nice! Thank you.

I performed this same test with a tuner I made on my lathe. The test rifle was a bone stock Savage FVSR that isn't really accurate to begin with and the short barrel didn't respond to the tuner very well. To say the least it was exasperating but in a fun way. I found I could make the rifle shoot worse more easily than better by making coarse adjustments like you did. I found a sweet spot and went back to it and pulled off a couple of one hole groups with some Wolf Match ammo but ran out of it and have never played with the tuner anymore. Then I found out that particular Wolf ammo isn't made also and I primarily shoot high velocity in the Savage anyway now for varmints and occasional long range steel targets. I wouldn't mind trying a better tuner on my 513 since it's threaded I regret now cutting the barrel back on it when I had it threaded I believe it was more accurate at it's full length.

I have one on my 24" 6.5 Grendel gas gun. I got the 2 port brake an tuner. I had factory ammo stacked deep. It really works using match ammo, SST an ELD bullets. FMJ ammo, can't really tell

Great video

It's the wind ,your a boss with that rig.

Great channel, great info! I use SK Magazine to baseline my rifles.

Good deal man. Thanks.

Yup may want to try a more consistent ammo. Tuning does not change with ammo brand, as long as bullet velocities are close. I enjoy your videos.

Thank you for the video! This is one of the best tuner videos I have found. Specially since I've been looking at one of these Harrells' for my Anschutz. Considering the price and availability of good ammo now days. Seems like a tuner is a requirement in order to have a decent day at the range (practice and fun) and avoid the overwhelming frustration, thus shooting worse as the days goes and frustration mounts, ;-). Makes me think I can use my giant case of Federal Gold Medal for practice and save the Tenex and Center-X for actual competitions. Once I get the settings recorded for each I can just readjust, verify and have fun. Without going bankrupt just practicing. I'll save the high end ammo for competition.

good stuff here! I was really hoping you changed ammo and you did!

Try the Hopewell method to tune. You are using an AR style tuner and not the true rimfire tuner. Although that will work it needs to be adjusted with a modified Hopewell method. This style tuner has 10 increments per revolution where the true rimfire has 25 increments per revolution. I have this style tuner on AR's and use the Harrell and J&L rimfire tuners on all the rimfires. Yes they help but you will need to adjust for change in ammo brands and velocities. Hopewell method is 10 shots into one target with 2 shots per revolution. Target 1 will be from 0 to 040, target 2 will be 040 to 080, target 3 will be 80 - 120 and target 4 will be 120 to 160. Yes you can get 160 even though not marked you can estimate. Now go back and look at your targets and select the smallest vertical stringing. Readjust the tuner to the lowest setting of that target group and start with 5 round groups adjust the tuner one turn and move targets for another 5 rounds until you get to the highest tuner settings for the selected group. Now look at the targets again and select the tightest group. Move to that setting and fire 5 shot group. Rotate 1/2 turn either direction and shoot another group at a fresh target. Move tuner 1/2 turn in the opposite direction from start setting and fire another 5 round group. Look at targets again and see which one is tightest group. Now you can decrease increments by 1/2 and continue tuning till you get the best possible shot group. I have found 1 increment can change the POI enough to throw you into a tizzy. Nice thing about this style tuner is you can go to minute adjustments where Harrells rimfire tuner stops you on a hard increment due to the detent. End result is if your rifle is setup properly the tuners will increase accuracy buy finding the barrel node point at the end. Please note that tuners do not compensate for lateral stringing. That is a shooter problem. When tuning you need to be the only one tuning. No help, no changing shooters and constant atmospheric conditions.

Great videos and info on a never ending quest for the perfect group. I’m also a tinkerer and should stick with the same ammo but I don’t and the tuner is my next toy I think. I wonder if sorting that SK ammo would have made a noticeable difference in those groups. Anyway, thank you very much for your time and passion for our sport.

Number 7 is where I would start.

Thank you sir. outstanding video. I just started playing with a .22 after plinking for years. I purchased the Bergara BMR carbon and mounted an Arkin EP 5 on it. I'm shooting 1/2 inch and better at 50 yards. I just put a Timmy hit trigger in and I am considering a Harrel an EC tuner. My sons are beginning to compete. I doubt I get into competition, but I can go out and shoot with now and then. God Bless and keep the videos coming.

It was a pleasure to watch this intelligent presentation, though I must agree with your wife; all those groups are terrible considering the pricey equipment you employed. Perhaps it would be prudent to try a different brand of ammo. I would like to see a follow-up to this, if you do.

Man, don't be sorry, this is awesome information. I would like to see you do a ladder test while changing your torque on the action screws

Top channel for rimfire thank u

I have found that if you weigh your shells and get them as close as possible to the same weight that it reduces the flyer by quite a bit. You can use any weight system because you are not concern about the weight but getting them with in the same weight. Hope that works for you. Thanks a lot for the videos that you put up here I enjoy them a lot.

Mr. Revolver Guy you can`t make every person happy so just make yourself happy. Most people can see you are a very trust worthy person so let the others talk and just enjoy what you are doing.

I would say that you would have to readjust not only for each brand but for even changing lots.

That tuner is really going to come in handy for quick succession firing, to decrease barrel vibration movement between shots. That's why they say for AR-15!

Great! Now I need a tuner LOL!! :-D

Tell that guy holding the target that there is nothing to be nervous about! Lol.

Thanks, I bought the ATS tuner for my Bergara b14 r carbon fiber trainer. I had the same experience with Eley Club. Still trying to find the sweet spot

Thanks for the video. Enjoyed every minute of it. Do you realize the rabbit hole adjusting a tuner you dug yourself into?😊

Great video just ordered a tuner brake on seeing how well it worked for Will be well pleased if I can match your results with SK long range match in the Annie 1761

Great video , suggestion ......CZs are notoriously good at showing the effects of Rim Thickness and pressures .....it’s hard to see effects of tuning if Ammo has random pressures . Your left hand and left finger keep moving ... as well as your cheek position , I can tell by the space between the brim of your hat and the scope eyepiece during the shoot. I’m more worried about pressures on the Stock. Overall these are some of the most informative on the net. Try using a Laser to see your wobble and dry fire ...

Good shooting. Ammunition can make a difference.

I gotta say ur thumbnail made me click. Awesome rifle. I love the sk ammo. I love these kind of test!! Great job

500 rds = 100 bucks. It's a crime!

If you want a good barrel tuner a limb saver deresonato and you don't have to worry about all that stuff collecting in your barrel and the limbsaver works if you want a good barrel tuner

Tune 0 and 7.... so 7 and 2 lines!!!!! Lovely... that last group after seasoning shots seemed close though

Very interesting. I wish you would have shot another 5 rounds in the next target to see if it was consistent.

Hi Big Guy It’s all about fun and bettering myself

Thanks fella, great video as usual 👍don't compete myself, just having TOO much fun tuning and tweaking all sorts of ammo and ranges 🙂 Regards to you and your family.

Hey from Ireland . Keep your cheek on the stock till all shots fired hard to remember to do but helps with groups

GAR Martin I noticed when you have a flyer the bolt handle seems to move a little. Maybe the bolt is not quite in the fully locked position

Now with the tuner the best for that ammo,get some class Ely ammo and retune

Informative video! Thank you. Just Sub’d 👍🇨🇦

i heard that barrel tuners can work pretty good but you still have to have ammo that is consistent enough to make it work. Need a good ammo that maybe the barrel doesnt like that still has good SDs and ES and can probably bring the groups tighter

Both fliers were at the same poi. That indicates ammo to me, not the rifle, or the shooter. I've had this happen to me on occasions.

I just purchased the Harrell Tuner. The Rimfire style. I am very interested if it can help my CZ 457 with cheap CCI SV it will be interesting. Thanks for the video.

I wish you lived in my area, I'd love shootin' some 22lr out at the range with you!

Getting stuck? So the wife still loves ya!!! Good too hear! Get her some flowers just cause!

I'm using the ATS tuner. Still trying to find the best setting.

Thanks for the video I think I'm going to get one and try it! By the way what rest are you using, do you have a model number and a name?

Would love to shoot with u. Thanks. I agree, let’s find enjoyment with every shot and every day and every buddy

Group 7

Tuner is working great but ammo not so much. You need to use better more consistent ammo and retest for us...thanks for your time. Good job...

Love your videos. I think you saved me the price of a tuner. You probably would have been better off with better ammo. Rifle match or Center X. Really appreciate what you do

In my humble opinion no "tuning" is required. Great shooting !

with my 223 20" remington barrels I need to shoot 7 times, full revolutions everytime and I will find at least ONE good node to set Harrels tuner at. I have used all 16 revolutions technically 17 if you start at 0 and have found TWO and sometimes THREE good nodes so seven revolutions works just fine starting at 0 with a Harrels tuner my best five shot groups without and with have been reduced from 5/8" to 3/8" @ 100 yds.

What size threads does it require machining your barrel to? I have a Krieger 1.25" straight contour barrel. My builder doesn't want to thread the barrel any smaller than 1" x20. I'm looking for a tuner or tuner brake designed for .22LR rimfire with a 1.25" barrel

Hi Harrell I notice that you seemed to have trouble seeing through your scope with the safety glasses on, they are not a good thing to use when shooting as they tend to magnifier and distort the image that you see. We found this was apparent when shooting at the ranges here in Australia try using your ordinary glasses if you have them and you will have better groups.

What does the tuner actually do? Or how does it work?

Where I'm from, "Harrell" is pronounced like "barrel".

Well I just place an order for the AR15 model. Let's see how it does.

What scope are you using?

Accurizing 22LR is tantamount to Sisyphus’s punishment and requires a masochistic personality type.

Great video, but will never have a shoot off with my two brothers ,(I'm the middle brother) Older brother doesn't do 22lr. Younger brother doesn't like competition.😯😩😞

Hey how do I get some of those hostages target

What kind of tuner is that? From which manufacturer?

How did you get interested in precision shooting? I love your comments, and the fact that you don't have a potty mouth. I love paper punching with my CZ 455 also.

Sk mag does throw flyers. Good for field class not so good for serious fclass.

Which model tuner did you order? Did you have to get your bored out?

Need let that bolt action go

DATR, is this now the Harrell Rabbit Hole ??.......... keep shooting !!

What do you do with rifles with lots of copper fouling? No bronze brush?

Kinda think a ammo change would help

Was this test at 50 or 100 yds??

Just got mine. Looks great can't wait to get out and try it out this weekend. Super video! Please join my Michigan's Ruger 10/22 enthusiast page on Facebook. Come check out my tuner and share ideas. My tuner is specifically made for rimfire and looks a little different.

Could you hear me hollering to go to 3 and see what it does?

#1#7

Flyers might be lead buildup in the choke...

Looks to me that your conclusion is your rifle does not like sk magazine... I'd try Rifle Match or ely Match .both are more in line what you would shoot in Competition

How in the world do you get the gun so quiet? I don't see a suppressor on your rifle.

See how the Starik tuner is tuned. Same method applies for the Harrell tuner. kzfaq.info/get/bejne/rs9hocKS1OCoZWQ.html

get some windflags and watch those groups shrink

Big man if you could make one complete video without all your incessant gum bumping your testing would no doubt improve immensely. Lol Problem with this whole process is when you get it all tuned up it's going to be tuned to that scrap magazine ammo. Then you can turn around and do it all over again.

Mr. Revolver Guy *shoots .27 group* Also Mr Revolver Guy* with better ammo id get better results* sheeesh

I don't know how a tuner is supposed to work with inconsistent ammo. It isn't a magic bullet.

Actually after watching the video just take the thing off!
