maybe so, but there are a few who know how to do it, read up on it, go lrh.com there are a bunch of folks who do it but don't post it on sites like this for this very reason, go on over and read shawn carlocks post of his neighbor, who took a deer at 976 yards with a 300 Rum that shawn built him, Oh and BTW he's 13 years old.

But my honest opinion is cases the size of the RUM need a .338" diameter bullet or larger and cases as large as the 378 WBY need a .358" diameter bullet or larger. Anything smaller is way too much powder being squeezed into too small a hole and things like throat erosion become excessive.
I also agree with the post above for the most part. Unless you are not going to shoot it often barrel life will be short.
I am not sure what your intent is with this rifle but if you want a rifle that drops animals on the spot at close or medium ranges or you want to have an extreme long range rig, the 338 cal will out perform the 30s with these larger cases.
Some of the new 338 cal Ballistic Coefficients are really impressive and those large cases can push them at impressive velocities.
If you are married to the 30 cal I would choose the 300 RUM in a 28" barrel and push something link the 200 grain accubond. 3200 fps is attainable and the .588 bc is hard to beat.
SG,
the 338s are an option- the caliber isn't out of my view. I guess I'm moreso interested right now in the case type it's built off of and why I should choose one over the other. When it comes to wildcats, I would want something that's easy to get or make brass for without breaking the bank. I can live with buying custom dies that will last.

I tried to play RR's game, but didn't have the dedication or range to make it happen. MD is not too long range friendly.
I look forward to RR's handywork during end of Nov. Always a crowd pleaser.

Barnes,
one of the many, many parts of this whole long range deal you don't understand is, once you get your trajectory plotted, there are only three things limiting your distance
1) how much up you have in your scope
2) at what range your bullet drops into sub-sonic flight
3) your own ability at getting the parralex set, judgeing wind, and how well you breathe and squeeze.
RR
Yeah. All I know is that there is some aerodynamically funky stuff that happens when the bullet passes through the "transsonic" region (mach 0.8 to 1.2) that serious messed up the flight of rifle bullets. Apparently, the same bullet would be perfectly stable and accurate both above mach 1.2 and if fired below about mach 0.8, but the transition somehow wrecks any accuracy, but I've never found an understandable explanation of why.
