I have to thank all for their input on the 300 Win Mag loads, I believe it is JD338 that harps on RL-22 with 180 gr bullets and 75 grains. This load is what mine really likes (.540 group at 100 with 180 AB's). Also got under an inch with 200 AB's with RL-25, but the 180 load really shines! I have a model 700 Remington BDL with a 24 inch stainless barrel, don't know the velocity yet. It usually posts higher than the manuals in the past, the barrel is one of the old blued stainless ones from the early years!
