Hey guys trying to use the 285 gr BTHP Hornady's with Retumbo for my 338 LM and can't find any load data. I've found 275 gr swift & 300 gr Sierra data. Has anybody used this combo or have data? There is quite a difference in powder between the 275 & 300 gr bullets 80-89 for the swift and 85-94c for the sierras. Dont really know were to start. Any thoughts would appreciated.
Thanks Mike
