I just purchased a 7mm-08 and find it to be one of the best cartriges i have ever shot. I was looking for a 4th rifle and considered the 280/270 but already had a 30.06 so there was almost to much overlap
Too much overlap indeed. Look at the ballistic charts. The 270 & 7mm-08 are almost one in the same. Look for a smaller or larger round for your next rifle. You will be glad you did in the future. 257-Roberts or 338-win mag come to mind.
I overlapped too many guns myself so now I am paying the price.
