I HAVE A HIGH WALL SET UP FOR RIMMED CARTRIDGE AND AM READY TO REBARREL. AT THIS POINT IN TIME HAVE NEARLY DECIDED UPON THE 7/30 WATERS. HAVE I MISSED THE BOAT OR THIS THE MOST MODERN, NON-WILDCAT, SEMI-HIGH POWERED . AMERICAN PRODUCED CARTRIDGE OUT THERE? THIS WILL BE FOR WHITETAIL HUNTING. THERE WAS A CARTRIDGE BASED ON ONE OF THE BIG BORE CARTRIDGES THAT WINCHESTER MADE FOR THEIR MODEL 94 THAT WAS SUPPOSED TO BE EXCELLENT BUT I DONT THINK IT EVER GOT INTO PRODUCTION. IT WAS A SHOOTING TIMES EASTERNER BUT DONT RECEALL THE CALIBER. THANKS IN ADVANCE FOR REFRESHING MY MEMORY ON ANYTHING BETTER THAN THE 7/30.
