Is there any considerations needed to be taken when loading Barnes TTSX and LRX without any load data with a specific powder? I have data for standard jacketed bullets but there isnt any for the Barnes bullets using the powder I have. I am reloading for my 270win and was going to try both 129gr LRX and 130gr TTSX with RL 23. Was planning on using 140gr bullet data as a starting point since both those bullets are about the same length as the 140gr I currently use and wanted to make sure I was on the right track.
