I am looking for advice on building .338RUM with mimimum weight. I plan to shoot the 250 grain Berger bullets when they are released. Do you think that a 1 : 10 twist will stabilise them? What would be better? What would be the shortest barrel length practical without excessive velocity loss. What would be the thinest barrel profife without substantial accuracy loss on three shot groups. Action, thinking Remington 700 to keep cost down but have access to Lawton actions also. With a scope weight limit of about 20oz, what scope would you use? Thinking Bushnell Elite 6500 in 2.5 - 16 x 42. Mounts, need to be reliable and strong but light. Stock, thinking of Manners T4 but not sure? Brake, needs to be a good one. Any help and advice would be great.
