Just wondering if anybody has any good recipes for a 250 grain bullet coming out of a 19.5" 338 win mag? I've got on a kick lately for short barrels after seeing a custom 35 whelen with a 18.5" tube. My 338 is a Remington 700 KS Mountain Rifle. I kept the stock 24" barrel, didn't want to hack it up, so I am having a new 19.5 installed. Should be back from the smith in a couple of weeks. I know I will lose some velocity but shouldn't be to severe with a faster powder like RL15. Thanks for any info.
