Yes, I handloaded the 210ttsx. Max load was 72gr of H-4350 in a federal cases with federal mag primer. Coal length for my gun was 3.38 in. Vel. 2950. As always this load worked in my Mark 5 weatherby action but may not be safe in your gun.
I was lucky enough to draw a Utah Mt Dutton tag and took a nice 375 bull 3 years back.
