No argument, just a bit more food for thought for thoughts dropping in on this thread,
how this relates to positional shooting and why it is so important to understand the complete picture.
(because the OP specifically mentioned PRS).
Wind in perspective:
1,000 yards, 10 mph 90° wind at 29.9inHg (most of use don't shoot on the beach so that makes a bit of difference.). Using the much slower 123 number of 2950 and the bit faster of the 147 @ 2750 than "I" am getting for the example, to make the wind difference between the bullets appear greater.
147 = 1.8R
123 = 2.2R
The 10 mph wind difference looks scary at 1000 yards.. seems like a no brainer, but is it?
Really what is happening, is that we know what our hold is,
what we don't know is the winds uncertainty, so the correct way to look at this is not how we typically communicate when looking at the charts. The difference really isn't .4mil, but rather the difference in the wind uncertainty for each. For instance lets stay the wind is bouncing between 10 and 12 mph.
1,000 yards, 12 mph 90° wind
147 = 2.1R a .3 mil uncertainly
123 = 2.6R a .4 mil uncertainty
The difference between these is only .1mil uncertainly at 1000y - less at the average PRS distances
(yes we can start making all kinds of cases, but my hope here is that it turns on a light for someone. Sure we can increase the wind uncertainly, but also, remember in my personal case where I am actually generating 150fps greater speed difference..)
Wobble:
Now, if one of these, allowed the shooter to create a situation were they might reduce the wobble by greater than .1mil at ALL distances we have yet another thing to consider. Wobble tends to be circular so a couple of 1/10s of wobble, creates a much larger CE zone than a couple 1/10s horizontal of wind.
I don't want to get into the "free-recoil" debate. But in general, the guns shoot better than we do. The more of "us" we impart into the gun the worse they tend to shoot.
I think it is always better to be able to see the short range impact and just getting too old to want to carry some of the crazy heavy guns I have seen at the top of the scale. That
leaves me with one choice and that is to manage the recoil. That said, there is a huge difference between a light load on the stock & comb and a heavily pressed rifle. Soon as we start leaning into our guns we impart the wobble. The wobble can be worse than the difference between the BC numbers. I am sure anyone who has shot a lot of positional shooting, can attest to just how small the load window is between no-wobble and too much. So weight and the recoil of the round all can't get taken out of the mix if you are seriously looking at the full picture.
Is a few 1/10s of semi-predictable wind
(wind in the same general direction) easier to deal with, or is unpredictable wobble that creates a much great CEP?
