Adjusting tunner

[zeke06]

It's my first time messing with a barrel tuner and just looking where to start or any tips. Also i can shoot up to 30yds indoors or would I be better off at 50 ?

I have one myself and from what I've been reading, start at the half way point. Like 5 if it goes to 10. Shoot and check your pattern. Adjust out a turn or less and see if it makes any difference. It's a "try me" thing. If you're shooting bug holes, don't bother with the tuner.

My golden rule is: "Be very methodical and assume everything you have read or heard about using a tuner...is WRONG!"

Yes, shoot at 50 yards. Or whatever ranges you'll use.

Some competitors use different tuner settings for different ranges. Same for different ammo lots.

It all depends where bullets leave on the muzzle axis upswing.

Rim fire shooting is so ammo dependent . It's not uncommon for a top shooter to spend
$ 15,000 on ammo a year . So tuners are used to adjust each lot
With a tuner with detents you will find one to 3 tunes per turn . Good luck Larry

That is a good write up and is pretty much how I tune with one. You must be very methodical. Moving several marks or even revolutions at a time is not being metodical. The most common mistake people make is making too large of adjustments. With my tuners(as well as most others), I recommend moving one mark at a time. If you move in any other increments, you are MOST likely to skip over a sweet spot. The sweet spots repeat and there are typically at least 1 per revolution on a rf and at least 2-3 per revolution with a cf rifle. It's really so simple that I can teach a 10 year old how to use a tuner in only a matter of a few minutes, given a known good gun and load. A big part of why, is that they haven't been told the wrong way to use a tuner for years and have no pre conceived notions. They're a clean slate, unlike most of us. --

The ONLY issue I have with a tuner is the amount of ammunition needed to find the correct setting for every single typ of ammunition I shoot. I have a setting for Lapua Center X, and another for Midas, then SK Rifle match etc... Took me a good 2-300 rounds for each setting to find it.

You can use the Purdy Prescription just search that online and will find the instructions , I have used it and got me real close. I sent my rifle to Dan Killough , Killough Shooting Sports and it is worth the money for them to do that. They do that sort of thing all the time. Top notch guys to deal with.
