Re: Same Powder Different Lot ??(Please read)
I can't imagine only buying 1lb. of Retumbo for a 300RUM. For your bullet weight it's just about the best pick and if it has worked in the past do yourself a favor and buy it 8lbs at a time. You would also be better off to buy enough of your 210's in the same lot# to launch with that 8lbs. The Berger's can vary quite a bit from lot to lot too.
