Anyone know if the latest edition of the Hornady manual has data for IMR 4451 with 6.5 Creedmoor 140/143 grain bullets? My 9th edition doesn't. I have data from Hodgdon's website, but I usually like using more than one source.
Sierra has some data. It goes up to 43gr which was way too hot. I was shooting 2916fps with a 140gr with 42.1g. Stick to the Hodgdon website. Lyman shows 40.5g with a 140g at 2660.
