My .338 Fed loads use the 185 gr TSX and 200 gr Hornadies. I don't shoot Partitions
. But if you want to use them I'm sure a .338 Fed will shoot them just fine.
I use Reloder 15, at 48 gr for the 185 TSX's and 200 gr Hornady Interlocks.
This pic is of the 47 gr load, but the all worked the same.
I think the same or similar loads would work fine with a 210 gr Partition -- start lower, of course, and work up.
They're producing around 2600 fps out of my 18.5" barreled Ruger RSI .338 Fed.
