i hate to resurrect a 4 yr old thread but i'm also interested in the trophy bonded tip bullet and case being nickel plated? will they wear the barrel anymore than a copper or lead bullet. also, will the nickel case wear the bolt any more than a brass cased bullet as the bolt slides over the case to eject a cartridge and chamber another? these have been the most accurate cartridge in my .308 win but i don't want to use them if the barrel/bolt wear are greater than a brass case and copper/lead bullet. what are y'alls thoughts on this?
