[edit] Sourcing

Most of the content I've added, such as muzzle enegies, velocities, and the intention of this round can be sourced from the book "Cartridges of the World" but for the life of me I cannot seem to remember the Wikipedia format for citing from a written work instead of another website.

I'm not sure what version of COTW you have, and I'm not sure if this is exactly right, but this is what I use.

Cartridges of the World 11th Edition, Book by Frank C. Barnes, Edited by Stan Skinner, Gun Digest Books, 2006, ISBN 0-89689-297-2

== Comparison claims

There were a lot of comparisons in the article that seemed to be quotes from Weatherby marketing material. I added charts for reference to evaluate these claims. Arthurrh 21:26, 1 August 2007 (UTC)

  In fact, the article still sounds to me like more marketing material than fact.  (It "outclasses"...??) Please continue with your efforts to 'neutralize' it, if at all possible.

[edit] Ballistic performance and test barrel length

Due to this cartridge very large case capacity in relation to its bore size a 26 in (660.4 mm) long barrel as used in the “info box - ballistic performance” section gives not the most realistic examples of the .30-378 Weatherby Magnum or its ballistic twins ballistic potential, though the stated performance figures in this article are very credible. Barrels that are too short in relation to the employed cartridge will produce sub standard muzzle velocities, unnecessary recoil and lots of muzzle flash, smoke and report. The main cause for these effects is unburned propellant. Custom made rifles for these kind of super magnum cartridges generally sport 762 mm (30 in) or longer barrels to take advantage of the ballistic potential of these overbore cartridges.

Weatherby created the cartridge, and Weatherby recommends and uses 26" barrels. Even though longer barrels can be used and would provide higher velocity, the 26" is a more realistic number since that is what you'd get if you bought a rifle from Weatherby. Arthurrh 17:51, 7 September 2007 (UTC)

[edit] Energy Comparisons

I returned the original comparison statement of the capabilities of the .30-378 vs. .458 Win Mag and .338 Lapua. The figures and testing are taken from "Cartridges of the World" and expert Dick Metcalf via "National Rifleman" I would add the citations myself but being a bit of a wiki amature I do not know for sure how I need to do that. If someone would leave me a note here telling me how to list said references I will be glad to do so.

Also .30-378 is capable of exceeding the .458 Win Mag by a high degree however this requires bullets in a weight over 220 grains which are hard to come by factory loaded, and I am not positive if Weatherby still offers them. I will double check and see because if this is something only handloaders can do now, I will change the edit to reflect that.
