    What would be the best powder to use to obtain the most velocity without compromising accuracy in a Weatherby Mark 5 Super Biggame Master.

    I own a accumark in 257 wbymag and IMR-4831 and 115 grain noslers work the best in my gun. This is a deadly combo for deer. Good luck.

    Moen,
    I have been looking at the 257WBY Accumark because it is available in LH. How accurate have you found it to be? Do you only reload or do you have experience with factory ammo too? How much meat dammage with the 115 gr Noslers?

    Thanks for any input, you don't see a lot of them at the range to ask the owners opinion.

    RB-I am no means a expert shooter just experiance out here on the prairie over the years but get 3/4 inch groups at a hundred yards fairly easy with heavier bullets.Still working on lighter ones in the 85gr range for coyotes.As for factory ammo I dont have alot experiance with it but to break in barrel, pretty expensive to shoot at $45 or more for a box.This is one round where it really pays to reload.Also helps with accuracy due to the long throats,seat the bullets out as far as magazine allows.As for meat damage,well I wouldnt go for the "Texas heart shot" if you hit solid bone in front shoulder it is devestating(throw both away)keep em in the boiler room,neck or even gutshot(not on purpose)and they go down quick.
    Like I said earlier I'm no expert,but if your looking at an accumark in 257wby for deer hunting I think youll be happy.

    Quick hello to Nodak 7mm,leon told me about site pretty interesting stuff.
