[QUOTE="bigngreen, post: 604098, member: 13632"] Getting closer to launching some of these, kinda hoping they shoot it took $90 to get them on my door step. Here's the info on them from the web site. [COLOR=#3F1C13]"This bullet is designed with the Seal Tite Band shifted even more forward with a smaller ogive radius and is for the .338 Lapua Magnum that will accept a COAL of 3.600-3.715� or for other .338 magnum rifles that are magazine fed with shorter magazine wells. COAL will be the brass trimmed to trim length + .999� bullet projection for preferred Seal Tite Band position. A minimum 1-10� barrel twist rate is required with muzzle velocity of 2800fps or greater. Real world BC of .650 was calculated using muzzle velocity of 3130fps and actual drops from 500 to 1500 yards. Muzzle velocity was established using a .338 Lapua Magnum rifle with a 34" barrel with a barrel twist rate of 1-10". [/COLOR] " I'm shooting them out of a 28in 338 RUM so I doubt I can get the 3130fps they did with their 34 in barrel. I modeled the bullet in Loadbase and the BC looks consistent with what I've been able to get with other bullets I've modeled and shot. The closest bullet I could find that has been BC tested is the Lehigh 245gr solid hybrid bore rider which was tested to be G1 of .651 by KnS Ballistics Services. [URL]http://freepdfhosting.com/4626d2127d.pdf[/URL] I would think the Cutting Edge bullet would be close to the same BC, it looks like some of the CE bullets were offered up for the next round of testing and I'm looking forward to see the results. I'm hoping to find another bullet that might correspond closely to the same BC as the CE bullet but at a more budget friendly level so I can get a few hundred rounds shot in the wind to get a feel for shooting a bullet at that BC, I can't afford to shoot hundreds of these to get a feel for how they shoot in the wind so my putting them on game at long range hinges on being able to find a practice bullet. It would take something super sexy to give me the same fuzzy feeling as dropping a 300 gr OTM on game but can't knock it till ya try it I guess. If anyone has any hints on a load or expectations let me know, I've only loaded 300gr SMK's and the 300 OTM's. [/QUOTE]
