Hi Joe, I dont think 200 yards is much different than 100 yards. maybe worse, because now you have 200 yards of wind swirls to work thru. unpredictable wind swirls....
I think AlexanderJ has it pretty much nailed ... the one shot just doesn't define the impact of that load very well ... in general, I think that the one bullet hole is somewhere in a circle of about twice the diameter of an average group of that load.
Dan's fine rig was giving 5 shot groups of about 1 inch, so any one shot I suggest is somewhere in a 2 inch circle drawn around it.
The fact that his ladder shooting seemed to walk according to the powder charge, while terrific to see, is probably something like drawing a straight in poker ... ie not very likely, although I seen it with my own eyes.
Also, the ladder thing is complicated by the effect of both how ” good ??? ” the load is, and how well the load matches the “tuner” sweet spot.
I believe that the * ladder * thing is probably more related to going thru a Tuner sweet spot than actually falling into some magical ” good load" ....
Going back thru the years of Precision Shooting, and yes Fouling Shot, me of the I Believe In Tuners Club ..... (g) ..... have to wonder how many very complicated and time-consuming tests were done in ignorant ( ie not experienced ) bliss of not even knowing about tuning barrels ...
Just finished reading for the 8th time * Bullets Flight * and Geepers if they had only known about tuners ... and especially if Dr. Mann had had a Vic 20 to sort data with .... Even Harry Pope gave Dr Mann “heck” for not trying different loads ...
Since your adandonment ( justified ) of testing ladder theiry, it would be good if you thought about::
Which is better... a mediocre load that is right in the sweet spot of a tuned barrel....
or a really great load which is not in the sweet spot..... or could even be in the worst tuned match with the barrel ...
Now THAT would be a world-class project, a guy should be able to put that on a spreadsheet somehow .. OWCH.. there is that migraine again.
Hey I just got in a Lee Special order 22 mold, a ” 22 Bator .. real cute, a blunt little thing, maybe I will cast with it and that rcbs to see how they compare. Anybody want a .22 Bator, I bot a couple extra to hustle the special order aong. off forum if you are interested. I hope to cast some yet today, won't get to shoot them today tho.
