Received the Lee Speed back from reboring today -really fast!New rifle now inside. The 338/303 is a perfect cartridge for this rifle .Fed some reloaded rounds from the magazing and was slick as a greased Buffalo.The gunsmith inclued some fire formed cases and the bullets after test firing .The 338 is an awsome game bullet.Will start with 338 Federal (338x308 winchester) starting loads and go from there after fireforming. The Speed will soon be ready to hunt.I will try to upload some pictures and publish range report shortly.
