i recently aquired an older plain jane winchester 670 in 30-06. it has a 22" barrel and a cheap scope 3-9x that is coming off soon for a better one. my question is what is a good bullet for deer and what weight? the guy i bought it from swore by the 180gr win. supreme ballistic silver tip. he gave me a box with three left and said they have been good for him with everyone he hit being DRT. my thoughts are the 150 would shoot flatter and 180 hit harder. what is the effective range of the 30-06? most places i hunt will be 150yds max but there is a pipeline that will stretch that a bit. any advice is greatly appreciated. also im a newbie to this site so hello all.
