For me, it’s a .300 H&H, hands down. When I had my .300 Win Mag built I agonized over doing a .300 H&H instead. The Win Mag is a great rifle that does everything I need it to, but it’s not a Super-Thirty.
As I get older I’m less enamored with having lots of different calibers and would rather have a nice rifles in a handful of calibers. A Blaser R8 is on the top of my list, and even if I have to go with an entry-level option I would like to add a Mauser or Sauer to my Steyr. Can you tell I like German rifles?
The exception to my general rule is that I’d REALLY like to have a double rifle in .450/400 one day. Heym or Merkel tops my list but I’m not going to be picky if someone would like to buy one for me!
