Sincerely appreciate the info and sorry for my delay in replying. Reading the comments above I am definitely thinking RUM over the Lapua. Thinking a proof research CF barrel 28" or maybe 30", with brake. I am looking for a top notch precision action but no need to be fancy. Your thoughts...
Thread right up my alley as i am planning on building a couple .338's. I really luv our 300 RUM's but was thinking i would go the the 338 Lapua, as i figured the commonality and source of components would be better??? Maybe not , eh? What are most using for actions in either the RUM of Lapua in...
I don't consider myself an expert but have for many years reloaded for 2 300 RUMS. In my experience Retumbo is far and away the best for my application! I do not have my reloading data in front of me but do know I exceed the SAMI spec. Great results
Being you are not reloading yourself the above calibers mentioned are great
I personally would go with the RUM, starting with ELD-X 178. Good BC and a ton of FPS
You could increase the bullet weight, which in some cases improve the BC
Just my 2 cents
