[QUOTE="cadborg, post: 2951312, member: 73138"] I am having my first full custom rifle built. Caliber is going to be 338 Lapua. I currently have a factory barreled 1/10 twist Remington LSS left hand 338 RUM. It shoots 210-265 grain bullets fine, but I am planning on shooting 250-300 grain bullets with this new build. I prefer mono metal bullets for hunting, such as the Barnes LRX, Cutting Edge Lazer or Badlands Bulldozer type. When I plug these bullets into the Berger stability calculator at 338 Lapua speeds, it looks to me like I should be looking at between a 1/8 or 1/9 twist barrel for "solid" stability through the full range of conditions I hunt in (300 feet to 7000 feet elevation, 10 degrees to 80 degrees F temp depending on the game animal). My only experience is with my 1/10 twist 338 RUM, so I am hoping for some info on what will be the best twist for the types of bullets I described. I also don't want to make a mistake and go with too fast a twist, leaving me possibly stuck with a small selection of bullets the rifle will theoretically shoot well. In case anyone is wondering - I am moving away from the 338 RUM, mostly due to the availability of brass and reloading data, but also because I might eventually re-chamber the rifle to 338 Lapua improved. Any help would be appreciated. [/QUOTE]
