I like my 416WBY, but I converted my Ruger Magnum bolt gun in 416 Rigby. [img]images/icons/smile.gif[/img]
My Grandfather's fav is the 300WBY, he's had it forever and pounded tons of Moose with it many a year.
Problem is, guys adjust the die down on the shellholder and get to loading, paying no attention to how far they're pushing the shoulder back, which is TOO FAR to keep the shoulder snug against the chamber and the case well aligned with the bore... improper die adjustment IMO.
Black Hills and Midsouth Shooters Supply has Federal brass for the Ultra, I'm told, which shouldn't be a soft as Remington stuff.
Federal case weights are all over the place, remington's a bit better. I did measure the Remington stuff I had from three seperate lots of factory ammo. A 4 grain spread in case weight proved to only be less than two tenths of a grain spread in actual case capacity when weighed with water though, and that was checking all 60 cases. It don't get better than that.
Once you overload a belted case and it gets sticky over the belt, which they will, you can't size it down with a FL die like you can this same pressure expansion ring area on a non-belted case, simply an inferior design from a reloaders standpoint.
I'm not ready to get rid of my WBY chamber but, I do keep the pressure down below what expands the belt after the initial fire forming. If I could, I'd but Lapua brass for any belted case I could.
Brent, you mention the brass being of the same approximate internal capacity even though the weight is off by as much as 4 grains. This means the brass is inconsistent in its thickness. Now, when that brass expands to fit the chamber walls snugly and consistently...isn't the internal capacity inconsistent? In other words...the eventual external capacity is always the same at the time of pressure peak...namely that of the chamber dimensions. But the internal capacity at this same moment is equal to the (consistent) external capacity minus the (inconsistent) case wall thickness.
Not sure my mind is saying that clearly...leaving for prairie chicken photography in a few minutes...4 am!!! Gotta get some caffiene in me. [img]images/icons/smile.gif[/img]
Littletoes, some of the early ultra's had excessive freebore. With the pair I bought, I could kiss the lands with most hunting bullets and still fit in the magazine. I've also picked up a .223 and a .270WSM in a rem, and they both have "normal" throat lengths.
The .300 Weatherby can be made to shoot accurately, look at some of the 1000 yard benchrest match results. For an over the counter rifle, I'd take the ultra.
AJ300MAG-Yea, it was the early ones that I knew about. Didn't know Remington decided to do something right! My Weatherby shoots well, although just a deer/elk rifle. But it does like flat based bullets better. It was the premier 1000 yard caliber at the Pennsylvania club for years. I love mine, and would not trade it for a Remington, but COST, when we are talking over the counter rifles. I think the Weatherby action is quite a bit stronger too. Talk about over-kill!

I think the 4 grain spread in this case was not inconsistant case wall thickness but, rather inconsistant extractor groove cuts and primer pockets... that's my guess anyway. These factory loads were all fired, so the cases were formed to the chamber in my rifle pretty well.
Sounds like BS, but I assure you I was just as surprised myself. Anyone that weighs and segragates their cases may want to look a little further and weigh them with water too. The easy way is to tare the scale with each case and record the weight of water. I weighed the case, then both, then subtracted the case weight to learn what I did.
Weatherby, stronger. Boy that sounds like a good debate. [img]images/icons/smile.gif[/img]
Thanks for all the feedback. Boy, tough call. Sounds like the 300 RUM is getting the nod. Here's some more food for thought. I am currently not set up for reloading and will be buying factory ammo. Now how would the accuracy compare? I suspect with the riduculous price of weatherby factory ammo it should be of high quality and comparible to handloading in the accuracy department. One would at least hope so.
If you arn't into handloading, and buy the Weatherby, you soon will be. Or you just won't be able to shoot very much. The price IS high, and the availability isn't there. Of cource the same may be true of the Ultra Mag too. I have never purchased them, so don't know.
