[QUOTE="kraky, post: 147687, member: 180"] It's spring up here in Wisconsin which means weather from 30 degrees to 70 degrees but often winds of at least 10-15 mph per day. I went shooting the other day with a gun that has had a problem with vertical stringing. I found a load that works really good at 300 yds. Usually with sidewinds I get 4" horizontal groups. With no wind I get some pretty nice groups around 3" at 300 yds. The other day I'm shooting at 300YDS with 10-15 mph winds directly at the rear. I'm shooting out of a shed so maybe some wind comes over the top for a few yards. Anyhow I was getting vertical dispersion again....of about 5". Horizontal was about 2". Could the wind cause this??? I'm talking 180 tsx out of the 300 wby at about 3220 fps. WHAT DOES YOUR EXPERIENCE TELL YOU. [/QUOTE]
