I picked up a box of 285 ELDMs for my 338 Rum with a lil beast brake on a stock 26” sporter barrel and action. Hornady is less than zero help and need some load data or at least a good start point. I have H-1000 and retumbo and would prefer to stick with those for temp stability but I’m open to anything cuz I know a lot of guys like r33. I have Remington brass and any primers. Any info is helpful. Thanks ahead of time.
