I've seen a few homebrew tuners that seem to work. I wonder if the one you describe may be a bit light to be effective?
tunes a bbl just fine. A pic of a prs setup with a tuner. 6BR running at 2900 fps with 105's
Little over a inch @600 and right at 2" @ 1000. In good conditions off of a bi-pod.
If your shooting prs your going to running behind the crown with a brake or a can.
Tuners are great!!

3 oz will tune an HV barrel. Borden made some a few years back and others have also made some about the same weight that work. Gene Beggs tuners weigh 3oz.
Still sowin up theah?

It's still February, Mr. Wass. Of course it's still snowin' up here. Looking for 2-4" tomorrow to cover up some of this muddy stuff!
