    I just finished a 4 hour shooting day in Morongo Valley, CA. The wind shifted directions significantly and the velocity varied throughout the day. The club now has both 8 inch and 6 inch spinning steel plates at 300yds. Of course they only spin when you hit them. My little MVP is capable making those plates spin if I can dope the wind. I can successful hit them 2, 3 and sometimes 4 times in a row then the wind changes direction and or velocity and I miss. The miss tells me that the wind has changed. You would think I would know, before I send the round down range, that the wind has changed and a correction in windage is necessary. Well, I am not that good and most probably never will be. So, I waist two or three rounds trying to figure out how many clicks are needed to get back on target. On my scope each click is .1Mil or 1.08 inches at 300yds. Today it took 2 or 3 clicks to get back on target again. Then there is another wind shift and I miss again. The whole thing repeats throughout the
    shooting session. When I get really upset with my wind doping abilities, I take out the big gun. Somehow those 140gr 7mm bullets don't get pushed around as much as those tiny 55gr bullets. I have read most of the ballistic info and understand why they don't drift nearly as much. However, there is nothing quite like being on that big gun and launching those big bullets and seeing exterior ballistics in action. I think I will keep the Winchester Model 70 Extreme Weather SS in 7mm-08Rem. It makes me feel like a Marksman.

    Welcome to my world ;) . Competing with a .223 at 200-1000yrds makes reading wind absolutely vital as a skill and because you actually can't read the winds usefully at the range I do that at, it can be challenging to say the least. Not always a lot of fun having everyone else hit and I miss right or left by a bullet width from an almost perfect wind call. A .223 is going to get blown around hard by even trivial winds. If my calls are off by 3mph, I usually miss. When winds are too bad, like over 20mph, I just don't even bother with the .223 if I have ammo for anything else.

    Interestingly, a .308 with their relatively poor ballistic coefficient and unimpressive velocities aren't a lot better. 7mm and 6mm and 6.5mm, they bring the velocity and stupid high BC's in varying ratios which is why they're getting so popular. That's one of the reasons I'm pulling my .308 barrel and replacing it with a .243AI barrel. Since I'm usually dropped in the unlimited class due to rifle weight anyway, might as well compete on level ground with all the 6.5CM and 6CM and 6XC shooters on heavy wind days. Can't wait for my .243AI barrel. 6mm 108's at 3200-3300fps. Laser. Beam.
