Green,
Now you're talkin.....
Regarding inconsistencies in where the bullet struck;
We human folks are a wierd bunch. We want to "wish" the bullet hole into a more reasonable placement that it actually is. Bottom line it that it is where it is and must be left there. We can rationalize all we want but it only helps the bottom line of Primer/Powder/bullet makers.
As we, here at LRH, tend to gravitate towards more extreme cartridges, barrel life is becoming a major consideration.
It is in all of our best interests to be able to "work up" a load w/as few shots as practicable.
Personally, I am really enjoying the tail end of this thread. It looks like some of us are catching on just a bit more. When the tide raises all the boats float a little higher. Except those boats with too short of an anchor chain....
Again, the forum, is pulling through for the betterment of the shooters.
I don't have either the ladder test or the OCW method figured out yet but what I have noticed is that whenever I am testing two or more loads I ALWAYS (now) shoot the shots in a round robin sequence. There's something about the round robin thing that "rings" true.
If I'm going to do a latter test as above, with two loads, I'd even consider doing it simultaneously.
Thanks for your analysis. I was going to post mine, but was hesitant. I think you and I came up with the same results. I liked your words better than the way I would have said it.
PS: In my OCW testing I seems to show that the mass of the powder(grains) makes more difference than the velocity that it produced (unless its grossly different)?
That is, when shooting round robin, a load of say 74.5 grains produces a velocity of 2800fps and a load of 74.7grs produces 2800 fps the 74.5 grain POI is in the 74.5 gr target's group and the 74.7gr POI is in the 74.7gr target's group. And the groups are centered on signifcantly different positions on the two targets. Make sense?
