300 Weatherby Mag!

BigBarn
Does anyone out there know what is the best bullet, i.e. weight, and knock down/killing power, for the 300 Weatherby Magnum? When used for mule deer, at moderate ranges, say out to 400 yards.
I am leaving on a trip to Colorado, in the next couple of weeks, and would appreciate any input as to which bullet selection would be better than any other, and why.
I have a pretty good amount of Weatherby ammunition, in 180 grain, but I have never killed anything with it, so I am wondering if I need to address another brand, and or bullet weight, to make sure I cover all bases on this hunt.
Give me your opinions!

Thanks, BigBarn[:I]

    If you have been using the Weatherby Ammo so far, it will do most anything you need at that range. I don't suggest switching unless you have time to do adequate range testing of other ammo before the trip. Use what you know if you are going on a trip.

    My MArk 5 really likes the 180 ballistic tips. There is nothing wrong with factory Weatherby ammo. If it shoots accurately for you and you have it, use it.

    Thanks guys! You have confirmed my beliefs! I always thought that the ammo from Weatherby was consistently accurate, and reliable, so that is what I am going with.
    I will send pictures of the trophy buck that I hopefully shoot on this trip. Wish me luck!

    i have a lefty accumark with brake and just switched from weatherby 150 gr sp to 180 barnes x bullets. I shoot a consistantly tighter group with the heavier bullets. that really surprised me. i'm no bench shooter but 2 of 3 groups had 2 holes touching at 100 yds. i put them through the chrony and avg'd 3100 fps. i switched for an october elk hunt but after i return to texas i won't switch back to 150's for white tail, i'll kep the 180 barnes x's!
    happy hunting

    If it were my choice and I already owned several boxes of W'by ammo, I would do some shooting to decide if that ammo was accurate enough for that one possible 'across the canyon' shot. W'by gaurantees 1.5 MOA. At 400 yds. that is the maximum that accuracy will carry for mule deer, beyond that you cannot gaurantee you can hit the kill zone.
    If I were not satisfied with that accuracy I would handload some ballistic tips and accubonds to see what they will do. If you got better accuracy I would go with either them for mule deer. I would stick to the accubond or go with partition for elk. Barnes has tremendous bullet performance but I can't vouch for the long range ability of the bullets. I haven't shot them at long range to know.

    Mulies out here can get pretty big, but the .300 wthby is overkill. I use a .25-06 with 117 gr. Sierra's and have never had to shoot one twice. Biggest ones I have ever seen I estimate in the 350-400 pound arena. If I were you, I would use 165 or 180 gr. bonded bullets. Ballistic tips or regular lead core bullets are gonna make a mess of the deer at .300 wthby velocities.

    Save the seals-club a liberal instead.

    I might as well add my two cents here. In November 2005, I took my .300 Weatherby up to British columbia for a mule deer hunt, using 180 grain ballistic tip bullets. When I told my guide what bullets I had, he said "Tell me you brought some other bullets. Those things don't work." About Day Five, I shot a big five by five mulie from less than fifty yards; hit him right in the shoulder. Instead of the deer getting bodyslammed to the ground, he bucked up on his hind legs and trotted off. The bullet splattered on his shoulder bone, instead of penetrating. I never did find him, since he wasn't wounded badly.


    Go with a better bullet, like a Speer Grand Slam (my favorite), a Nosler Partition, Barnes X or Triple Shock, or a good bonded bullet. By the way, the Weatherby with the 180 Speer Grand Slam has taken a six foot balck bear, a 1,100 moose, and a 400 lb. woodland caribou.

    for long range deer i use 83grs. h-4831 with a 165 nosler ballistic tip boat tail bullet and it kills deer. this out of a mk-5 SS 300 weatherby with a 26 inch barrel with factory muzzle brake and a 6.5x20 leupold. for heavier animals i would switch to nosler 165-180gr. solid base partion bullets. eastbank.

    Marketing has hunters too often sold on using the 'latest & greatest'.
    Ballistic Tip heavy grain bullets especially at magnum speed & power aren't the best for short range shots (<100 yards) in heavy bone on medium and large game animals. Nor is it great for angluar shots like a shoulder in heavy bone. A frontal, or a rib shot would be better w/a 180. A 165 preferred if it has to be a Ballistic Tip.

    Some better all around choices in Weatherby ammo would be Barnes, Hornady Interlock, and Nosler Partition. Don't waste $$$ on boattails for shots <350-400 yards. Accuracy is usually so close, and the drop so minimal for a kill zone shot.

    Have extensive experience w/Weatherby and the only ammo that ever came close to doing what Weatherby ammo did, and was very accurate was the PMC Eldorado which came only in a gold or silver box. If you can find it, it is usually a good buy because no one knows about it especially since it was discontinued
