Has anyone loaded any 280gr Barnes LRX for 338 Lapua with RL-33? Neither alliant nor Barnes had tested them and would not offer suggestions. Any other load suggestions for the 280 gr lrx would be appreciated as well. I also had trouble getting info from them for 270 WSM 129gr LRX and 130gr TTSX with RL-17, I would appreciate any suggestions with this as well. I have asked about the 270 wsm on another forum and gotten a few responses that seem to agree 60-62gr works best but would like to have more input. Thank you in advance for any info.
