Doe...I think it was similiar for the .270, most of us are just too young to remember...It came out in 1925 if I remamber correctly...Because the '06 was used in WW-I and WW-II it took awhile to catch on...

My younger brother bought both a 7mm-08 and a .280 back in the early '80s, I think the 7mm-08 came out in 1980...At any rate, him and his son still use them and they have gotten pretty popular here in NC...
