Mm TCU
Another cartridge developed by Wes Ugalde and chambered originally by Thompson/Center Arms.
This cartridge is based on the .223 Remington case necked up to 6.5mm.
All the loads developed in our pressure barrel proved to be quite consistent. The 6.5 T/CU should be adequate for small game and varmints at ranges up to 200 yards. There is no SAAMI pressure limit for the 6.5 T/CU. Based on the recommendations of Thompson/ Center, these loads are limited to the same pressures as the .223 Remington cartridge.

Hunting Mastery Selected Tips
Deer hunting is an interesting thing that reminds you of those golden old ages of 19th centuries, where a handsome hunk well equipped with all hunting material rides on horse searching for his target animal either for the purpose of displaying his masculine powers or for enticing and wooing his lady love.
