The guy is a bench rest competitor and those guys will do anything to get better performance. Even if what they are doing does absolutely nothing. If it doesn't hurt performance then there is a chance it may help for that one shot needed to win a major title.
Yes, bullets yaw and pitch until they get to a hundred yards or so. The longer bullets probably 150 to 200. I saw some tests done on some small arms ammunition using spark photography at Aberdeen many years ago. You would be astounded at just how much they yaw and pitch until they stabilize. That's one reason why many of us do not put much faith in 100 yard grouping. 200, yes. 300 yards ideal.
Many years ago bench rest guys said that if the group strung vertically you didn't have enough powder. Horizontally and you had too much. I actually think this is more true than false. And would rather make a decision based on this than how small a hole is in a piece of paper. Paper tends to close up after the bullet passes through and if the paper has a high moisture content, the hole will be smaller than if the paper was dry. So I guess a guy can take a hydrometer or some sort and start recording how much moisture was in the paper. That is exactly what a bench rest shooter would do if he thought it meant a smaller group.
No big deal. Bench rest shooters have their own ways of doing things that work for them and are pretty much unnecessary for guys who go out and shoot some steel or hunt.
If I were trying to find a load for one of the cartridges I shoot, I would go to a web site like ours that specializes in that cartridge for my specific use and search to find out what the most common load is for the bullet and powder I want to use. Most likely there is one load plus or minus a tenth or two grains with the bullet I want to use that most of the shooters have found to be the best load. That is where I would start my load development and I bet that I would end up with the same load plus or minus .2 grains.
