RE: .270 or 7mm-08?
The 7mm-08 came out in 1980 (not exactly a "new Kid")...The .270 came out in 1925 if I remember correctly...
If your shots are over bean fields where you can have 300-350 long shots, I'd opt for the .270...
If your shots are in the woods, or a box stand where a little shorter gun would be a little handier, I'd opt for the 7mm-08...
One of my brothers has a 7mm-08 and has had since about '81...My other brother and his son both have a .270...When skinning their deer, I can't tell by the damage which caliber did the deed...
Where I live, .270 shells are easier to come by...The local WalMart still had several boxes of 130gr CoreLokts for $14.24...They didn't have any for the 7mm-08...Might want to look into that as well...
