I've been looking into building a long range boomer. I'm pretty much decided on a 338. Will use for deer, elk and Bear. Seems like most RUMs or Edges are in the 10 to 12lb range but looks like most Lapuas are in the 15lb+ range. I want a quality, accurate and shootable rifle with muzzle brake. I'm not that concerned with ammo or component availability because the rifle will probably take a year or more to have built. That said there's a lot of Lapua stuff available now. Would you go with a bigger, heavier Lapua given about the same ballistics performance? What should my minimum weight target be for a Shootable RUM or edge? Thanks for your input?
