[QUOTE="Long Time Long Ranger, post: 493402, member: 505"] Firecat, thanks for the info. The difference between your info and mine is in my rifles there is on average about 125 fps difference between the two rifles with 140 and 168 grain loads instead of 50 fps as you used. Also my input is both rifles zeroed 2.5" high at 100 yards which is a typical zero for me. If you use these you will match my data pretty close. I coppied the numbers I used straight off JBM. Energy is virtually irrelavent since Berger bullets are compared here. For energy figures to have an impact target bullets that fragment can not be included. High quality premium hunting bullets that retain most of there weight to use the energy to drive through animals is the key to energy. When a bullet fragments energy figures go out the window. I have both and shoot both and could care less which one shows the best numbers. I could take either and kill anything I wanted. I was just showing the figures right off JBM from the data I entered. Another thing that I was bringing to light is with quality premium hunting bullets for large big game the 7mm really starts falling off because of the poor BC numbers in premium bullets when compared to some other calibers. I have quite a few 7mm's and love to hunt with them. I keep them in situations where I get the most out of there performance. But any way you slice it the 7mm's are not as good a choice for long range shooting at large big game animals because of the poor BC numbers with premium hunting bullets needed for this application. You can go up to 30 caliber and get a 200 grain accubond with a .588 BC. In 264 you can get a swift scirroco at .571 BC.
