43 degrees makes a difference.
Beautiful to shoot outside, just a touch warm at 80 degrees. I was out playing with the white mountain carbine, shooting 350 grain maxihunters and 90 grains of goex ffg. Last time I shot this gun (last month), it was 37 degrees. My gun shot 5 inches lower today. What an impact this warm weather makes! I'm seriously considering having two different sight settings, one for cooler weather , and a hot weather sight setting. In Ohio, it can 15 degrees or it can be 70 during the gun seasons.
