On a recent trip I picked up some 140gr TSX's to try. SHould I use the Barnes load data for the XBT or is the TSX data different? If different can someone share the recommendation for RL22 and IMR 4831? Thanks

Barnes recomends that you start with their starting loads in published data then work up 1 or 2 gr higher than max in .5 gr steps. However, it depends on your rifle of course and what it max for it.My best load came from IMR7828

I've had considerably better results from RL22 with that bullet in 7mag. YMMV
