[QUOTE="Jason, post: 158138, member: 130"] I know this may sound like an odd comparison but I have a 7mm/08 Ackley Improved. I shoot Berger 168 gr vld bullets at 2748 fps. I was doing some comparisons on the computer the other day with a 7mm RUM. Shooting the same bullet at 3175 fps the RUM is only 15% faster and with 30 % more energy and 20% less wind drift at 1000 yards than the 7mm/08 Improved. (Less drop too obviously) What I would like to know is would you notice that in the real world? You would have to shoot quite a few animals at long range with both calibres to get fair data would'nt you? What I'm getting at is you pay a big price in terms of recoil etc for not a huge gain in power, Would this gain be consistently noticable on deer sized game at say 600 yds or so. (1000 yds only for camparison) Taking the 1000 yds energy figures as an example the 7mm/08 AI has 922 foot pounds left at that range, the RUM has 1314. Would that kill when 922 fpe would not. Assuming everthing else was exactly the same. ( animal size , bullet placement etc ) [/QUOTE]
