While the reloading manuals provide data for the .308 Win in bullet weights ranging from 100 to 200 gr 'pills', my experience with semi-auto mil-spec long arms, beginning back with the M1 Garands up thru the M1-As, is that the gas-chambering systems won't tolerate broad ranges. I haven't found much on reloading the AR pattern 308's. I would expect these rifles will handle the standard military bullet weights of 150 and 168gr., but what about the heavier hunting bullets from 175gr up thru the 200gr? Are there any sources and/or links on reloading these rifles? neverhome_rph "Never be afraid to try something new. Amateurs built the Ark, but experts built the Titanic."
