In the last years I reloaded the 7 Rem. Mag with Barnes TSX140 grs bullets and 67 grains of Vihtavuori 560.
OAL 3.28” (max.allowed by the magazine for proper feed).
In my area TSX are not available anymore and I am compelled to use TTSX 140 grs bullets.
Question: shall I reduce the powder charge or may I use the same load?
Thanks in advance.
