[QUOTE="nvschütze, post: 1687279, member: 110896"] I was once asked by a nice lady at Lee Precision why the .300 Nevada Desert Magnum (300NDM) is so named. I told her the cartridge was a .300-caliber, was designed in Nevada and has a .532" head, making it a "magnum." The .358 Sierra Stomper got its name because its "development title" was the .358 Sierra Mountains Magnum (358SMM). I kind o' took the name of the first one and bent it a little to somewhat match in sound its name to the first one. I was a member of ammoguide.com at the time; the gentlemen on that site watched as the first one came to fruition. One of the members posted that this .358" cartridge would have plenty of "stomp." That sounded so good to me, the round was subsequently christened the .358 Sierra Stomper because I figgered it would kill anything a hunter might find in the Sierra Mountains. The 300NDM is a target round (has a [I]total[/I] neck clearance of 0.001 inches); the Stomper is a hunting round; neck clearance is 0.005 inches. Considering SAAMI clearances on cases of this size is usually 0.006 inches; I think I did kind o' good for a n00bie at this mildcatting stuff. I call my rounds "mildcats" because I figgered the .300" was going to be just mildly more robust than a .30-06. It's not. The .300" produces right near 3600 foot-pounds of muzzle energy from 68.0 grains of powder. The Stomper produces 4000-plus foot-pounds at the muzzle with 62.0 grains of powder. A 250-grain bullet at 2624 fps retains 2300 foot-pounds at 300 yards, and is still moving along at 2035 fps at that distance. Both energies are plenty enough to flatten anything on the North American continent. [/QUOTE]
