[QUOTE="LRNut, post: 3041843, member: 3230"] When I lived in northern MN back in the 90s I noticed my .220 Swift dropped a lot more in -30 temps at 700 yards than say a 7mm bullet. The reason was the low BC. Low BC bullets not only drift more in the wind, their trajectory is affected a lot more by temperature. I had the Swift rebarreled to a fast twist and started shooting 75/80 grain bullets. Big difference in both drift and temp impacts. [/QUOTE]
