:shock: I have 150gr TSX bullets, Reloader 19 powder and 210 primers, the load data I have found from various sources recommends from 64.1 -73.5 reloader 19 powder. The data is not for 150gr TSX bullets but from various other bullet manufacturers with the same weight of bullet. I understand the TSX has less resistance traveling down the barrel which results in lowered pressures, do I have to compensate for the lower pressures with more powder? I hear the TSX likes to be about .050 off the lands so that is where I think I'll start. Can I get half ways close without using a chronograph? Any comments welocome.

If you'll go over to the Shortmags website You can find out what some of the other WSM shooters are doing with TSX's.

Anybody know where I can find Barnes X bullet load data? Barnes recommends simply adding 1-2 gr. of powder to the Barnes X load data to get the TSX load required.
