Found my 300 Win Mag load
After finalizing that it appeared to be a good load and doing Chrono I'm onto cold bore shooting, 1 shot, 2 max at 200yds. The first outing the hole was touching the center 1/8" dot on another target and today it was essentially in the center. Done and done, 180 grain Federal Trophy Bonded at just over 3000fps with some IMR4350. Next week I'll take a shot at a 400yd and/or 600yd target. I've found the Nikon BDC's are pretty accurate in the past with my .223 loads and my AR for prairie dogs.
Still working on my 7mm 140 grain Accubond but it should hopefully be within 1/2" of center as the last two were grouping around 1" at 200yds but I had to adjust the scope down and hopefully dancing on the bull next cold bore shot.
