I would suggest if the article is not sufficent proof then by all means get with a buddy and do the test for your self. You may be surprised.
As far are the programs windage info being correct? That is hard to tell as we perfect the drops( elevation) with BC and velocity tweeking to get them perfect. Again elevation is something we can get spot on. But windage / wind drift is not as we have no way I know of to prove what actual winds the bullet is actually traveling in. So with what I have to work with I can't call a program right or wrong. But, like I have done, we can prove which bullet does indeed have the most drift simply by shooting them back to back in like conditions. And the more samples the better.
One thing this has proven to me is to look at what is in front of you. Not what someone says. The small fast bullet coolaid does not taste good to me. Now a heavy fast bullet,... well that has a very appealing flavor. I have some of that brewing as we speak.
Ya, I am awful anxious to see what Shawn comes up with for your LRKM. It really sounds like the very best LR scenario! 338, the best brass, a fantastic platform, and his new throat design. Man, my mouth is watering right now!
Here is an example of what I am talking about. This data is for a light weight carry gun that my kids use/used when they were young and is still one of my favorite carry guns. It is a 30'06 weighing about 9.5 lbs.
As you can see the terminal velocity of the heavy for caliber 210 VLD only gets me to about 500 yards before I don't have enough velocity for consistent expansion. But with the lighter 168 VLD I can go out to 650 yards. Out to that distance the drop is much less and the drift is so close it isn't a factor in determining what to use.
This is in no way meant to prove my case in absolute, but it is just an example of a real world scenario where the heavy, high BC bullets don't make as much sense as a lighter mid weight bullet, at least for me. I get less recoil as well which in this gun allows me to shoot it a bit better and also allows me to stay on target a bit better after the shoot is executed.
I have a similar scenario with a 6.5 that shoots the 130 high BC bullets quite a bit faster than the 140's and provides a better ballistics down range as well.
I guess my point is similar to yours, everyone needs to shoot their gun with their loads to see how things are going to play out. I trust my ballistic programs more than you do that is clear. But I imagine much of that is due to the fact that I shoot mostly under 1000 yards and I think Ballistic programs are much more accurate there compared to where you shoot.
Thanks for your input here.
