[QUOTE="jmden, post: 324501, member: 1742"] D, I've spent quite a bit of time over the years looking into the various options in that .338 caliber. Droping an elk at one mile is a quite a quest. Exbal shows that with an MV of 2850fps (a bit more fps than many folks are getting with the EDGE w/30" barrel) and using the 300 SMK (probably the best bullet out there right now for this use) at 7000' (lower elevation will give you lower velocities and energies--higher ele. is kind of a best case scenario) that you'd be at 1356 ft.lbs. of energy and 1427 fps at 1760 yds. Not saying it's not doable, but that's getting pretty low energy for an elk and below the typical number that I hear (1600 fps) for any expansion of that bullet. In short, IMHO, you would need to look at a bigger gun. Now, if the 300g Berger comes out sometime here and has the predicted G1 BC of just over .9, your numbers would look better-- around 1620fps and 1747 ft. lbs. of energy. If I was u, I'd email Carlock and ask him about using the EDGE on an elk at a mile with the 300SMK--I would think that's a bit too far. The various 338 Lapua's improved will get you another 100-150fps over the EDGE, but with the 300SMK and 7000' sceneario above, I'd still say it's fairly marginal even in the best of conditions. Personally, I would think you need to look at the various .338's built on the 408 Chey-Tac case such as the 338 Allen Magnum built by Kirby of APS and others similar to that. Launching a 300SMK at 3300fps with those or so and the above 7000' still only gives you 1730fps and 1994 ft. lbs. at 1760 yds. If you are hunting at elevations below that, that numbers drop off. Don't want to get too hung up on the numbers, but they are at least representative of what can/should/should not be done to a large degree. Something to consider. The other cartridges mentioned pack no where near the punch to even consider elk at a mile in MHO. Good luck. [/QUOTE]
