Has anyone loaded any TSX bullets in a 7MM Rem Mag? I am having trouble finding reloading data. any help would be appriciated.

Barnes recommends using X bullet data as a start and working up from there. I don't have my old data manual at work but will give you the starting load later today

Here is the data from the Barnes #1 manual.
H4831 62 gr- 67 gr
IMR4831 60- 64.5 gr
RL22 61-66 gr
IMR7828 63-68 gr
These loads are the starting and MAX loads. I've had good luck with IMR4831 w/150 gr loads

My experience with the TSX is that you'll end up using 1-1.5 grains less powder than say a Nosler partition or Sierra for the same velocity. The TSX has shot really well in everything I've tried it in.
