In the early 1980s I was thinking about buying a 7mm-08. The Gunsmith cautioned me by letting me know it was a new cartridge. He indicated that you never know if a new cartridge was going to last 20 or 30 years from then. I did not buy one and as we all know it's still kicking around.

If you reload, there's no such thing as an obsolete cartridge.

Once you render an opinion, you open yourself up to criticism.
