[QUOTE="rscott5028, post: 611888, member: 24624"] In the context of the original post which was about shooting deer as far as 700yds, both cartridges are more than adequate with a lot of bullet options. I'm going by my rule of thumb which is around 1800 fps and 1000 ft-lbs at impact. Naturally, you have to hit what you're aiming at. But, dead is dead. If I follow your logic correctly, the guy should get a 338 Edge+P and shoot 300gr bullets as it will have a lot more enrgy a lot farther out than the 300WM. I dial for elevation past point blank range. So, drop isn't nearly as important to me as windage, adequate impact velocity for expansion, retained energy, and sectional density. This is what NF came up with... [FONT=Courier New]7RM 168g .284 berger .617 BC, mv 2900fps, 10Mph wind 500 yds - 8.63 elev - 12.6" wind - 2227 fps - 1850 ft-lbs 700 yds - 14.75 elev - 26.0" wind - 1993 fps - 1481 ft-lbs 1000 yds - 25.75 elev - 57.9" wind - 1672 fps - 1042 ft-lbs[/FONT] [FONT=Courier New]300WM 168g .308 berger .473 BC, mv 3200fps, 10Mph wind 500 yds - 7.25 elev - 14.7" wind - 2309 fps - 1989 ft-lbs 700 yds - 12.75 elev - 30.8" wind - 2000 fps - 1492 ft-lbs 1000 yds - 23.50 elev - 70.3" wind - 1589 fps - 942 ft-lbs [/FONT] It looks like a dead heat at 700yds with the 7mm having a slight edge on wind and sectional density. Either one is more than adequate to kill deer at that range. With more recoil and higher cost per practice round, you can get more down range energy out of the 300WM. I haven't pushed the 230gr OTM over 2500fps from my 300WM. But, I'm not using the best powder nor have I seen any pressure signs either. I suspect it'll top at around 2700fps. But, according to Quick Load, it'll do 2796 with RE50. [FONT=Courier New]300WM 230g .308 berger OTM .719 BC, mv 2800fps, 10Mph wind 500 yds - 9.25 elev - 12.2" wind - 2197 fps - 2464 ft-lbs 700 yds - 15.50 elev - 25.1" wind - 1979 fps - 2000 ft-lbs 1000 yds - 26.75 elev - 55.4" wind - 1678 fps - 1439 ft-lbs [/FONT] I just don't see that big of an advantage for deer at 700yds which is what the OP was asking about. Clearly the 300WM with the big bullets and more recoil carries more energy for bigger game. But, recoil is subjective. So, everyone needs to decide for themselves. I have both and don't really care which one you pick. If I'm going after deer and 700yds is the farthest I'll shoot. I'm going to use my 6.5x284 with 142 SMKs or 140 Bergers. They're all good and you can't own too many guns. -- richard [/QUOTE]
