[QUOTE="rbTanzan, post: 1562586, member: 53978"] Well, I like 338's, good bullets, and good wine. So blessings on you with your plans and build. Personally, I would go with the larger casehead, meaning Norma or Lapua. And between the two I would choose Lapua as having more reliable brass available in the future, including from Lapua. The 338 Lapua is well-designed. The Norma allows long bullets, but the same effect can be had from almost any bullet when it is "single-loaded" on top, rather than fed through a magazine. On throat and rifle twist I would check out various bullets and see what twists are needed for what you want. CEB, Hammer, GSC, and Barnes would be my first thoughts. Some of those bullets have BC's in the 800's. You may need to prepare two loads, one for loads in the magazine and then a single-round load on top of the other rounds that is too long for the magazine. CEB has a 265 grain .338" with an .800+ BC. Likewise GSC has a 257 grain with an .800+ BC. This last bullet is 1.91" long and has a recommended twist of 9.0", although a 10" twist would marginally work. As for the 185gn TTSX, it is a great deer bullet for normal ranges. I shot a Calif mule-deer three months ago with one at 302 yards. Face on, DRT, bullet exited diagonally thru back ribs. In a 338 WinMag the muzzle velocity was 3125fps. Since I hunt under 400 yards that was fine. For 1000 yards I would look at the bullets above. Barnes has a new 250 grain bullet with a .600 BC that is not too shabby! [/QUOTE]
