[QUOTE="remingtonman_25_06, post: 150512, member: 1403"] BH Thanks for getting in depth here. I'll try and answer your questions to the best of my knowledge, here goes. I guess I just figured 5-10MPH wind wasn't that much to worry about especially since it wasn't a direct crosswind. It was blowing 5-10mph, from about oh 4-5 o'clock, when I did the ladder test and I got the .349" group with 3 different weights, so I just thought I had the load dialed in really good. Or in other words, I dont see how on 1 windy day it shot under .5" with 3 different weights, yet on a different windy day I"m getting 2" groups with the same weight of charges, doesn't make sense to me...I know what my problem is, I"ll tell ya later...
