I just ordered my 120gr TSX's in order to work up a load for my new MRC 264WM.

Does anyone have load data that they would like to share? Is RL19 or RL15 a good powder to try with this combination?

Thanks,

Robert

I found a load of H4831SC from 51gr-58.5gr......Anyone tried this powder?

Thanks,

Robert

I know its a different bullet but I've had good luck with Sierra 120 grains in front of 63.0 grains of H4831. I'm thinking a fairly slow powder is the way to go with this much case capacity.

In my loading of a 264 I found RL19 a little on the fast side. I never tried RL15. My go to was H4831 and later MRP. RL22 would be worth checking as well as 7828.

My accuracy load with 120s is 60 grains of IMR4831 in my 264. I know it is below max, so it should work with the TSX.
