Looking for some ideas for a 338 caliber build. I think I am leaning toward the RUM, mostly because it’s a factory chambering and reloading should, in theory, be simpler. This gun will be built on a Savage 110 action that will not use the barrel nut. I have two questions: 1. What barrel length and twist would maximize performance with 250-300 gr bullets?2. What are other available bullets for the 338 (besides the 250 and 300 gr SMK’s) that are suitable for long range shooting? I guess my goal is to try and approach the performance of the Lapua and the Edge with a more common cartridge. Thanks for any insight.
