the .270 gives you a little more room with bullet weights
No offense intended but how do you figure? Factory loads for the 270 you can find 130 and 150 if you look hard. 120 and 140 for the 7mm but really what else would you need? Now handloading is a whole new ball of wax. 110-175 for the 7mm, 100,130 and 150 for the 270. Personally I do everything I need to do with a 130 out of a 270 and a 140 out of a 7mm-08. BTW, I have a 300 Win Mag and after I got the 7mm-08 and 270 all it does is gather dust.
