Gentlemen ,l Please allow this !! I shot my .270 Weather Mag at a Long-Range school. One year I used the 150 Grn Nosler ABLR with a G1 BC of .591, at 3000 fps, and I hit every target at every range to 1200 yards with very few misses. It was a clam day and the instructor was calling the wind. I to 2 Min wind hold on average. The next year I shot the same rifle , at the same school, with the 130 Grn Ballistic tips, G1 BC .4XX at 3300fps, and it was VERY windy. I missed most of the targets, due to lack of correct wind hold. Extremely difficult to hit even with 10 to 12 min Wind Hold. My take a way is the heavier projectile you have ( 156 grn) with the higher BC , is better in the wind at longer ranges, than the lighter bullet. At least it was for me. Just my 2 cents. By the way, the shooter to hit the most targets , on that windy day, with the least misses, was the shooter who was using a Custom Precision Rifle, in 300 PRC, with bullets in the 212/220-gran range.
