    Looking for powder ideas. Nosler only lists a few. Still pretty new to reloading so all I have on hand is h1000 but am looking to expand the powder selection.:D

    RL22 can be a might temp. sensitive, but rare is the 300WM that won't shoot 75 gr. behind the 180BT & Fed 215M very, very well.

    I have used H4350 and RL22 with this bullet.
    Accuracy (.3") with my rifle and this bullet was found at 69.0gn of H4350 (3094fps) but I took it up to 71.0g (.7" and 3154fps) but settled on the milder load at the time. I was using the 9.5M primer.
    With RL22, I settled on 75.5gn (book max) and used the BR2. Accuracy ran .752" for a five shot groups with an average velocity of 3093fps. During the warmer months, accuracy ran a little tighter and velocity was about 20-25fps faster but this testing was done in Novenber (northen VA).
    I also tried the 190gn SMK with RL25 and H1000. RL25 didn't show anything promising in my rifle but H1000 with the CCI250 was excellent. The tightest group I ever shot in this rifle (.142") came at 79.0gn, velocity averaged 3078fps. It was hot that day, 94deg with heat index of 110deg, but I took it to 80.5gn in 1/2 gn increments and accuracy stayed under .522".
    Another good bullet/powder combo was the 178gn A-Max with IMR4831 and the CCI250. I only tried 72.5 and 73.0gn and settled on 72.5. Velocity was .2995" and velocity averaged 3168fps. 73.0gn was .5375" and 3238fps.
    Hope this helps. JohnnyK.

    I use 73.5grns imr4350 under the 180s with BR2s and a 3.450 oal for a hunting load. Its fast and accurate.

    Win WXR suppose to be identical or close to RL 22. Best part is an 8lb keg 104.00.

    Really like the 300 Win Mag

    180 gr Nosler AB
    76.0 of RL 22

    Used a lot of IMR 4350 over the years with 180's in the 300 WM

    71.0 grains of h4350. Chronos @ 3240, 26" barrel. Less than 1" groups.

    My velocity seems high. I want to chrono it again.

    RL22, RL25, H1000 and Retumbo are my picks this week.
    As stated, 75gr of RL22 is good, 81gr of RL25 is excellent, 80gr of H1000 is OK and Retumbo is untested in my rifles, but have heard good things about it.
    The 180gr BT is a very accurate bullet and is really good at long range.

    Cheers.

    I have been using H4831 (72 gr) and achieving consistent muzzle velocities of 3100 fps.

    +1 On that. I also used H4831 but only 70gr with a 180 gr Nosler and put 3 rounds inside of a dime at 100 yards from a rest. Didn't chrono it though.

    IMR4831 and range work can produce small groups.

    If you're chasing the highest velocity, all the Ramshot Magnum you can get in the case with a Fed215 is your ticket.

    If you want the best velocity and accuracy look to Imr7828 and Magpro with CCI250s.

    If you want the most accuracy look to Imr4350, H4350, H4831, and Ramshot Hunter with a Fed210M or CCI BR2.
