RE: IMR4350 loads for 280rem/160gr Nosler Accubond
my serria book has 44.1gr min to 51.1gr max. for a 160 gr bullet. 2300fps to 2700fps. serria recomends 55.4gr of Viht N165 for accuracy load 2600fps. hunting load is RE-19, 54.0gr 2700fps.
the lyman book has 45.0gr min to 51.5gr max for a 162 gr bullet. 2300fps to 2700fps. they claimthe max is the load you want but i dont recomend it. good luck!
