I just love nostalgia. Have a few older loading manuals from Speer and Hornady and some loading data that my ole man used way back in the late 1950's. Worked up a 270 win load that my dad used in his remington pump. Found that data in my 1965 Hornady manual. Load was very accurate fired from a Savage 110. Don't want to list it due to liability issues, besides what works for my rifle may not work for yours. My question then is... Are the new load manuals and data nowadays somewhat watered down? Been using Hornady and Speer manuals dated from 1966 to 1973 using IMR powders with excellent results. Is this a bad idea?
