Load developement with tuner

[100FUEGOS]

I think it was a matter of temperature ... The load was tuned to 4 degrees and in the test there were 24 already, hence the additional 10 meters second ... And maybe it made me leave the node ... I think.
The barrel is 28 "and 1.10" in outline ... the synth is 2.5 "long and 1.10" in contour ... And make a revolution over 12 minutes ... adjusting every 2 minutes from zero.

The thread is in metric is 1 to 100 ... very fine step ... I think it is something like 1 mm per turn.

I have a Left Hand Browning A Bolt 338 Win Mag with a tuner on it that is also a muzzle brake. I hand load, set the tuner and worked up a load. I may speak heresy but seems to me the tuners are for those who shoot factory ammunition, and do not hand load. Mine shoots about 3/4" at 100 yards.

Now that you have worked up your load, start making very small adjustments on the Tunner...get ready for a real SHOCK!

Thanks - I will try it when I can get back to the range (broken ankle)

Got to do some more testing last weekend . Magneto speed doesn’t work well with tuner ( unsure why ?maybe blast pattern from tuner ? ) Ran fine on naked barrel ? Anyway I found a couple nodes , and they repeated 3-4 clicks in or out . I think my trouble was I should have moved the tuner a couple clicks when seeing shotgun groups during OCW testing , as I believe I was in a dead spot ( out of tune ) while trying to find optimal charge weight . Very impressed with the results , just need to modify testing method ( went one turn out and never adjusted ) Probably should have tweaked it a bit from the get go after seeing terrible groups . As with anything you learn as you go ! My 2 cents is to have your barrel scribed or marked/ etched as marker ECT smears and doesn’t stay put . Tuner is quite sensitive and when you see the next comments you will learn to interpret what your seeing , definitely different than tuning naked barrel . Could clearly see target literally change click by click . Went from mediocre group to horizontal , to vertical , to bug hole in 4 clicks . Congratulations to Mr Ezell for his wonderful invention . Post #22 sums it up , get ready to be SHOCKED !! These things work ! Now to move back .... Thanks to everyone for there help , greatly appreciated.
