[QUOTE="aramarine6, post: 800269, member: 24685"] I've had issues myself trying to find data for the 338 RUM. I was looking for info on the hornady 285 grain match bullet and H1000 or Retumbo. Couldnt find a lick of info anywhere and even hornady said they had zero load data with that bullet in a 338 RUM. So. I took info and load data for 300 grain SMKs and 250 SMKs and interpolated them. I then started with what I thought was a very weak powder charge of 90 grains and worked up in 1/2 grain increments until I saw pressure signs. So far as of this writing I've made it up to 96 grains of H1000 with zero pressure signs and groups continue to tighten. Now I also have wiggle room in that my COAL is 3.72. So my pressures are reduced a bit. If I were looking to load the 265 LRX I would use 250 grain load data and go from there. Always start with the minimum. I know this isn't very scientific but it worked well for me. Maybe theres a member here with one of those high speed ballistic/reloading programs that can run the numbers for you. [/QUOTE]
