retraction, retraction!!!! bigcountry is correct....makes not a wit, according to my books, reloading the 270 with H or IMR 4350. The numbers are that close. I apologise to bigcountry and only offer my ignorance as an excuse for you see, nothing in our hobby is set in concrete. I don't know what else to say....have been reloading for 40+ years and should have known better....when you think you know it all......well you don't. Good discussion here, however. just be careful when applying same numbers with different powders....not good as a rule. Regards, Rick.
