I am contemplating at 338 mag in the near future. 338lapua AR30, 338-378 Accumark, or 338 ultra Sendero. the sendero does not have a break. if I get this one I would likely change the stock to a Choate Ultimate varmint or Ultimate sniper. Or a McMillan Prone or Tooley. I would not be carrying this rifle long distances so would make it heavy for comfortable shooting. how much should this gun weigh in order to really dampen the recoil? I am not looking to make it feel like a 243 win but acceptable to shoot off the bench for lets say 20-40 shots at one sitting. I was just trying to avoid adding a break.
