    This is the final load result in 300WM Ruger M-77 Hawkeye that I worked up for my cousins rifle. The Accubond and Ballistic tip are virtually the same shape and share the same published BC numbers.

    RL-17 @ 68.7gr
    Win Brass 2.610
    Fed 215M
    Nosler 180gr Ballistic tip
    COL 3.320, .467 off
    Velocity 3026fps

    Group .388"

    It feeds from the magazine well without issue. The throat was deep and the jump is quite far but it shot very well.

    Ruger® M77® Hawkeye® All-Weather® Bolt-Action Rifle Model 7125

    I tried a variety of loads and seating depths with RL-22 and IMR-4831 but the RL-17 shot best in his application. All seating depths tested were set at max magiziine and shortened in .020 increaments with mid loads until a nice group showed up. Then charges were increased in .07gr increments until good numbers or pressure showed up.

    Start your testing below my final charge numbers and work up with traditional safe practices.

    Use the max load listed on the accurate website for Magpro. It is the best load that I know of for the 300 winchester. My 24" barrel rifle is shooting the 180 grain Cutting Edge bullet over 3300 fps with no pressure signs. My accuracy load was one grain over the listed max. I have shot 300 win mags since 1969 and this is the best load I have ever shot. Have never got over 3200 before.

    I have a great load that works in my M77 MII all weather ultra lite, its Norma brass, CCI BR2 primers, 73grns Imr 4350 with a OAL of 3.487" .030" off, shoots 3116, slight resistance with bolt lift, this load is way over max book, 67grns is a good start.
