Questions About Tuner

Over the last several weeks I have gotten into shooting 22br and recently purchased a Suhl with a Harrel tuner (no weight kit as of yet). I have searched near and far and read numerous threads on the net but can't really find much information about tuning a barrel. I've read a few threads here that gave some information but still left me with some questions.

My main question is about adding weights. I remember reading a thread here the other day that stated something about shooting two different types of ammo and adding weight until each ammo fell into the same group. Then once you accomplished this you would start adjusting the tuner itself until you find the sweet spot. Have you guys done this? If so do you feel it is a good way to go about tuning.

So, what do you guys think. Should I add weight until I see the groups I'm looking for and then fine tune by turning the tuner or should I just forget the weights for now and do some tuning with the tuner and try and determine if I need extra weight or not? I'm pretty good with rifles but this part has got me a little perplexed. Also, if there is a link or thread that explains all this please point me in that direction as I have not been able to find sufficient information by searching. Thanks.
 
Check out rimfirebenchrest.com. Look at "worth reading". Several different approaches.

Range Junkie welcome to BC! i would answer your question like this,

A tuner takes out vertical sometimes referred to as stringing. Try the tuner just like it comes no extra weight.

If your testing gets you out towards the end around the 400 mark (and you still have vertical) your about out of adjustment. Add some weight 20-30 grams to get you back "on control" of your adjustment clicks.

Start back out at 100-200 or so and if you reach the end again and run out of "clicks" add another 20 grams or so and go back to about 100-200 and start again.

I add weight if need be to keep my tuners in the 200-300 range, past 300 clicks they feel a bit loose to me, your starting to walk off the threads with the outer shell. joe

Hey Joe , I feel like you might have meant 2-3 oz. , instead of 20 -30 oz. If not my bad. I know most of the guys i sell weight kits to want to go 1/2 to 1 oz. at a time. Good luck to our brand new shooter there. CS

THANKS FOR THE CORRECTION!! Isould have said grams in the first part!! I got it right the second time, lol. Sorry if there was any confusion and thanks for help me out Flykiller!! joe
 
Thanks Joe, that make perfect sense to me now. I did a lot of searching an reading and did find some helpful info here including a thread you wrote entitled "Tuner Adjusting for Newbies" or something along those lines but I had a hard time finding good info about weights and how much to add.

I found another thread about ringing the barrel and using a stethoscope to listen for the ringing and/or lack thereof at the muzzle. I tried this and found I didn't need a stethoscope to hear it. I guess my ears are better than I thought. I could hear an obvious ring in the mid section of the barrel but as I tapped toward the muzzle it was just a dead thud. So, I guess some would say I have enough weight with the tuner alone. Have you guys tried this and do you find it's an accurate way to at determine if more weight is needed? I know the ultimate test is to shoot it but I'm curious how many of your think this barrel ringing approach has some validity.
 
I'm by no means an expert... I never read how or why to add weights either but as i gained experience with tuners it just made sense to me. My theory is when the tuner is almost out of clicks, add some weight to get it back on control.

I was just trying to give some kind of example -your tuning method will probably be different than mine.

You will probably find more than one sweet spot for your tuner. I have read use the spot that you can go a few clicks either way and still be in tune... that will be for you to decide. just remember to have fun!! joe:)
 
Cart before the horse?

The first thing you need to do is to find some consistent shooting ammo. You then use the tuner to make a tiny one hole group. Finding the ammo is the hard part. Erratic shooting ammo can not be tuned to be competative.
 
Carp, thanks for the link. That was some good reading.

Pete, I have been shooting some Laupa Center X and plan to order some Eley black box soon. We have one more match this fall and I'm kinda of winging it at this point. I haven't had much time to test different ammo and work on the tuner setting. I plan to do a lot of that this fall and hope to find some ammo she really likes. Right now I'm just trying to acquire all the things I need like, front rest, rear bag, wind flags, cleaning gear etc. I'm having fun though and that's the main thing. I've been shooting rifles and pistols all my life and I've always had a quest for accuracy but this is my first attempt at competitive rifle shooting. This 22BR stuff is so much different than shooting large calibers with all the wind adjustments and such. I've shot some 30 calibers out to 600 yards just for fun but the wind readings with the 22s is so much different. I really enjoy it.

I had some pretty good shooters helping me along so far. I started out shooting borrowed gear from one particular guy. I borrowed his rifles, rests, bags, everything. I even shot his ammo, although I paid him for it, of course. Heck, last weekend, we had a three gun match and he wanted me to shoot in the sporter class, which I hadn't planned to do since I don't have a sporter class rifle yet, so he loaned me a sporter. I finished second to him on the 50 yard target. We both shot 246 but he beat me out with X count. It takes a heck of a nice guy to just hand all his gear over to someone he has only known for a couple of months. Anyway, I'm having a blast learning all this stuff, shooting the matches, and just getting to know the people involved. If you seasoned shooters have any pointers for me, I'm all ears.
