    I've been loading mostly 150s lately but, I've got a few hundred 180 MKs and a few 180 NBTs I'm planning on trying in my new 700 Police after I break in the barrel. I've also been considering using the 150 Accubonds, they've worked well in my 06'.

    I was planning on using R22 and H4831 to push the 180s. I also thought of trying IMR7828 w/ them as well.

    What are your favorite 300 Win Mag loads?

    Thanks,

    Reloader

    H4831 and RL22 with 180 and 200 grain bullets. I have had better luck with CCI250 primers.

    I am holding a 1/2" pattern at 100 yards with 76 grains of RE-22 in a Winchester case with a CCI Magnum primer and a 180 Grain Nossler Baslistic Tip. I am seeing an adverage of about 3100 Fps. I am shooting this in a Browning Medalion A-Bolt with the BOSS set at 8.1

    Hope this helps good luck.

    The second load I tried, 20+ years ago was a Hornady 165 gr. flat base, Win 8½ primer and 80 grains of H4831. It was right out of a book, but I don't remember which one, right now? Never tried anything else, still puts 5 under a quarter @100 yds. Recent data claim it's a hot load, so be careful.

    Good hunting. LB

    Win brass, Fed 215, 200 gr accubond with 68.8gr of IMR 4350, velocity is 2850. Had to back off from 69 gr as brass life was getting short - velocity was 2950.

    I also was shooting 165gr Ballistic tips at 3250 with 74gr of IMR 4350 (max load)

    Everything is seated to mag length.
