Ive owned a 358 BLR for near 30 years after I saw how effective it was in my hunting partners hands loaded with a 250 grain speer bullet over 44 grains of imr 4064, and in all that time (35 plus years) theres been other guys in our elk hunting club that have purchased similar 358 win BLRs and I'b be amazed if more than 3% of the cartridges fired through any of those rifles did not have a 308 win head stamp. as a result I don,t see ammo as a serious concern in a 338 fed which is very similar
