I shot a couple of rifles today with some tricky wind, tricky for me anyway. Probably no so tricky for some of you guys. I had around an 8-10mph constant with it pushing on up into the teens frequently. Switching directions on me at times also. Shooting at 500 yds with a 180 7mm eld @2830fps mv & 147eld @ 3150 fps mv. I was able to stay around 1 moa with normally sub half moa loads in very little wind. Easily dead animals on all of those shots if I had been hunting but I proved to myself that I need some improvement on my down range wind reading abilities. Both the 147 & 180 drift ballistics calculate to near identical at those speeds mentioned at 500yds. Majority of the wind was from the left. I landed several 180s & 147s on top of each other with them being to the right and just a touch low. Which is what I expected with out holding for any wind. I basically wanted a non scientific-field result comparison between the two bullets at that distance.
