I guess I can add something to this rather old thread since it has been resurrected.
Bart and Billy were watching me shoot at the now defunct Rachel’s Glenn range in Alabama some years back. Both said it was painful to watch.
No fancy rest, just an old Hart with a home made windage top. A rear bag that was used when I bought it. (I still use it).
I never have and still do not shoot fast. I can if the need arises, but I usually watch the flags and pick the condition.
Sometimes this works quite well, sometimes not. But, I did discover that in 100-200 yard score, learning how to take your time and watch every little nuance in the condition is a big plus. Since you are having to move the Rifle from target to target, all sorts of gremlins can appear. I tend to treat each bulls eye as an individual match.
I am now a better score shooter than group shooter, mainly because in my area, we shoot a lot of score. I approach score different than group. I shoot my 30 BR free recoil. At Heavy Varmint weight, it is not that bad.
One thing that I believe is extremely important in score is to avoid what I call a horizontal tune. That is when the rifle is shooting flat, but any little change what so ever pushes the bullet to the left or right off of the X. If you can’t see what did it, you are in a horizontal tune.
This is where a tuner really comes in. You can do an ever so slight adjustment, get the rifle shooting round holes again, and hit X’s.
In group, you will see shooters stringing 1 inch straight across flat groups at 200 yards, and some one will say......”at least it’s in tune”
The truth is, it’s not. My rule is, if you can’t see what caused the bullet to go where it went, then the tune ain’t right.
