View Full Version : Adding weights to a tuner

07-27-2009, 03:47 PM
I'm a little confused by the weight and tuner thing so I've got a few questions. I've just ordered my first tuner after a nice conversation with Herrell's. I also ordered a set of weights to go with the tuner. My question is how do you know if a weight(s) are required and if they are how do you know how much? Is it the same as with out weights and a trial and error process? I've read the 2 shot and adjust procedures and intend to use it to look for accuracy nodes. But for the sake of argument letís say three nodes are found and one proves to be more accurate than any other. Do you then add a weight and see if that improves the group or do you just go back through the whole process again? Just trying to clear this up in my mind so any help would be great. Donald

Really? No one has any thoughts on the use of weights.

All the way back to Harry Pope, shooters have use some sort of weight or barrel extension for tuning. Harry refereed to his, as a False Muzzle.

I hope you are joking. Pope's false muzzles were for loading. They come off before firing or, if left on, during firing

try this, set the tuner at the middle of it's range with no weight and test, then add the smallest weight and test again, if it's the same or better change the weight you have on for the next size up and test again. When you've found the weight it shoots best with then you start twisting in and out on the tuner to fine tune. Takes a lot of ammo but I don't know of a short cut.

Go to page 5 and read the thread "Tuner Adjustment". You will soon note there are as many opinions on the correct way to tune a rifle as there are rifles.
At my gun club the guys, every few weeks, upon seeing the pile if .22 brass say "looks like Al has been tweeking his tuners again". I love to tinker and the quest for the one hole 5 shot group in all conditions.

To ans. your question. I shoot a group without a tuner. I then add tuner and weight untill the group is 1/2 inch lower. Next I play with the Hopewel method.

Now it looks like von Ahrens has designed a better mousetrap. I have ordered one and will have the pleasure of burning more ammo in my never ending hunt for the perfect barrel, ammo, tuner combo. I mostly use Eley Match.

I shoot what matches I can get to but I guess my hobby is precision benchrest plinking. I do love seeing a bug on my target.

I shot 5 shot groups @ 50 yards starting with the tuner on an even number no fractions (ie. 1 - 5). I moved the tuner one number for each 5 shot group. Once I found the number that gave me the best groups (2 nodes) I put all the weights on and did the same thing. I didn't get to remove any weights because the thing was shooting so well & we ran out of daylight. I'm very happy with the 5 shot groups @ 100 yards ranging from .475 - .604 on it's current tuner setting. That is normally way better than I'm able to shoot so I'll see if it repeats fairly close to those numbers. I'll try to shoot in the evening next week. No sense to punish the rifle & ammo for my gross inadequacies on wind reading.

The question of how much weight depends on too many things to answer the question accurately. Kind of like "how high is up"? There isn't a correct answer to the question. But, I'd say if you find a setting that will shoot day in and day out and do well you're on the right track. Some rifles will shoot lights out on a good day and mediocre on another day, usually because of not being in proper tune. Finding the "right tune" can be a deceptive thing.
On my rifles I work with a certain "favorite" barrel length and contour, and from past experience I can get pretty close with a certain amount of weight on the tuner and do minimal tuning from that point. In one case I used the same tuner and on 3 different barrels and did not move the adjustments and it shot well and won matches in top competition. Barrels were all the same length and contour but made by 3 different makers. But, you change the barrel contour and length, and everything changes.

Thanks for the responces. Guess there is no secret hand shake for tuners & weights. I'll start with no weight and work up from there.

Now another question comes to mind. All thing the same if you shoot 2 types of ammo, "I.E. eley/lapua,SK/Wolf or what ever", that have the same over all speed in your rifle do you find that the tuner/barrel stays in "tune" or does each ammo even if all things are the same have a favorite setting that's much different. It would seem to me the tune is about vibration and speed and not so much about bullet weights/powders/brass and such. What has been your real world experience on this? I'm really looking for the real deal experiences and not theory on this as I've learned that theory and 22's stand up about as long as Snow Balls in hell. Donald

I saw these on Highwall 22RF, im the late 60's. They were outlawed by the Schuetzen clubs in the area, and the gun never showed up again. He also had some 32/40's but they were not shot at the RF clubs.

Uh...no. A false muzzle was a piece of barrel cut of and dowell pinned so that a cast slug could be accurately muzzle loaded before accurate breach seating a fitted cast slug was developed.
