Get a Barnes reloading manual it will give you the loading data you need. It will not list TSX bullet loads separately but will tell what bullets they have that it will match. They also say that TSX bullets can be loaded with a little more powder. This is the safest way to go even though others may wish to share there data with you. I do not have my Barnes Manual with me or I would be able to tell you what the bullets are. In the newer Barnes Manuals the reloading data is updated to correct for the errors they had in the past.

Good luck and safe reloading

Barnes recommends,
XMR 3100- 40.0 gr. to 44.0 gr.
IMR 4320- 32.0 gr. to 36.0 gr.
Win 760 - 38.5 gr. to 42.5 gr.

Primer- Federal GM 210M

My son-in-law called Barnes on just this question. The guy he talked to recommended up to about 44 gr. H4350. When Varget was mentioned, he said they had been getting very good results with it up to 38-39 gr. Both our rifles shot very well with 38-Varget, so we stuck with that. Last week I finally tried the H4350. Got 3/4" groups with 44gr, but didn't have the chrono set up to check speed. I'm getting 3084 fps with the Varget load out of my M70 Featherweight, but this barrel usually checks a bit slow.

Email Barnes. They should be able to send you an Excel spreadsheet with all the load data you'll ever need. They hooked me up in the past when I was doing some testing (before I got the #3 manual).
