rcmuglia,
In the article I specifically talk about the possilbe effect of thrown charges in long-range shooting. I believe the specific example I used was my 6.5-06, where I load 56 grains of H1000 with 140-grain bullets. If I weigh the charges, the rile will group three shots into something less than 1/2 MOA out to 600-700 yards.
If I threw them with my old measure (the one called Brand X) in the article) I'd get about a .5-grain variation, or even a little more. This would open up groups at least an inch at 600-700, mostly by vertical dispersion.
After using better powder measures in other loading for the past year or so, I'm now eager to try throwing loads for the 6.5-06 and seeing what happens. Have just about shot up my supply of loads put together with the old measure and will be doing that sometime soon--but in the article I certainly didn't suggest throwing loads for 1000-yard competition.
