Powders for 300 win mag

I have a question about powders. TO thins point I have been using IMR 4350 with excellent results, however due to conditions beyond my control and the advice of some other shooters I am looking to change up powders and would like some advice before I spend my money. I am shooting a remington sendero in 300 win mag. I currently use winchester cases, federal 215M primers, 200 grain BTSP sierra GK's, with 68.0 prains of IMR4350. Recently my barrel has been shortened and recrowned, the IMR doesn't seem to be working for me anymore. I am curious to know if anyone has any experience with IMR 4831, H4831 & 4831SC, or Reloder22. Keep in mind I live in Northern Alberta and shoot almost all year round, meaning temp. changes from 30 degrees above zero to 30 degrees below zero (celcius).

    I shoot 71.0 grs. of Reloader 22 with a 200 gr. Accubond, Fed 215 primer, and Win Brass. Gives me great results (.5 moa or less @ 100yds.) from 75 deg. down to the teens.

    Just a thought since I use IMR 4350 as well - maybe trying Hodgdon's 4350 would be enough of a change to get your rifle shooting good again and it supposed to be temp insensitive. I know Hodgdon has their new "Experimental Packs" with 4oz of 4 different powders (for about the price of 1lb of powder)that you could try - if you can find one. I have only seen them at gun shows around here.

    Jaeger476,
    I have had many 300 win mag's over the years
    some like one powder better than another but
    you can allway's find a load that work's good
    with RL22

    p.s. so winmagman is steering you in the
    right direction

    Jaeger476, I am with these guys on the Reloader 22. I am shooting a Remington 700 LSS with a Brake & started out using H4831sc & never could get a group under MOA with it. I switched to RL-22 & my best group has been a 3 shot .3" group @ 100 yards. Good Luck, Dean-o
