I just bought a 15" 7-30 Waters Barrel for my Contender and just scoped a 14" .223 Hunter Barrel that I have had for a while. I know a lot depends on bullet/load etc. but how should these cals. be sighted in at a hundred yards. I plan to use the 7-30 for deer with 120-130 gr. and the .223 for Varmints( woodchucks and coyote) with 50-55 gr. I sight my .308 rifle 2.25" high at a hundred yards and I can pretty much hold dead on from point blank range out to 225 yds. Again I know there are variables but what do you guys do, on average? Thanks.
