The way I remember it the 7/08 came on a little slow in the early years, well known to rifle looney types but not especially by average or ordinary public. It is now 40 years old and about as popular as the .270 was when it was 40 years old.

Some of you may remember hunting talk around the barbershop in the mid or early 1960's and many participating did not know what a .270 was back then.
My point is that now there are enough rifles in the 7/08 caliber out there that it is not going away.
