I have 2 7mm08's a small Remington Model 7 I have set up for hunting UP cedar swamps, A Remington 700 mountain rifle set up to hunt deer long distances across cranberry bogs and on the beach.
I hand load a 120gr, Sierra HPBT game king over a charge of IMR 4350. Fine cartridge low recoil, yet does a excellent job on harvesting deer.
You can use 308 brass 243 and 260 also if you can't find 7mm08 brass. I've never had a problem.
