My list of powders for my 1982 vintage Rem 700 35 Whelen BDL: RL15, RL15 and RL15. Best velocity and accuracy. I shoot Hornady 250 SP's and RN's into under an inch with around 58.0 gr of powder.
Dropped a nice 5x5 Bull Elk last fall with the 250 SP at a confirmed 554 yds. That's as far as I would have stretched the old girl and the we couldn't get any closer. Try RL15. You won't be disappointed.
