Working up some loads for my new 7600 30-06 in inter bond 165 grain. Hornady has a starting of 42.4 with max of 51.9. Lyman shows 47.0 starting and 52 max with a 165 jacketed ballistic tip. The several posts I find show guys having the best luck with anything from 46.5 up to 50+. Starting at 42.4 and working my way up seems like it could result in a lot of waste. Thoughts?? Also at what distance does one recommend working these loads with open sights? Thanks
