I did what I could to help the horizontal spread today with that tether I mentioned above. However with today's testing I did see some vertical stringing too.
Today's testing... was suggested by Harry Tobin... He suggested shooting the whole number increments from 1 through 5 just to see what would happen in that spread of barrel length change.
The tuner can add .500" to the barrel length total.
Each click of the tuner adds .001" to the length. (starting from minimum of course, it can also reduce bbl. length...depends where your starting and which direction you twisting the tuner and testing.
Here's the target/graph for today...
Shooting conditions were good, that wind today didn't do anything like it did yesterday. Light gusts to 8 or 10mph but they were few and far in between.
I have 'lettered' both pages of these tests now so we can refer to any single group by giving the horizontal line they are on (letters from A to E & the vertical columns are lettered F through N.)
This way we can refer to a specific group as, for example today's warmer target as location... 'B/G' that should take all the mystery out of what we are talking about.
Here is the Pg-1 of this series...the wind of the first test was up in the top of the page...it was '0' that day. In the future the wind will be in the box where the warmer target is.
For not ever having done this type shooting or recording such information on the targets, I know it is a bit vague...for that I apologize and will try to work out a system that'll work better on the fly.
