375 load

[steve71]

I want to work up a load for my 375ruger. I am using 300gr barnes TSX and Win 760 powder. Barnes says
71.5 to 78.5 grains for this powder and bullet. Any one have any thoughts on this?

Too many variables to answer this. Start low and work your way up. With TSX pay attention to bullet depth seating.

I usually work up to find pressure in about 0.5gr increments, watching velocity as compared to load data, but I did a 338 Win Mag load the other day with 210gr TTSX and just tried out five of the lowest charge. They were touching at 100 yards, and going a bit over 2700, so that was the end of load development for that rifle.
Edit, point of this is that it depends if you're needing extra power out of that or not. If you are ok with 2,437 fps, then just start there with 5-10 rounds and see how they do. If you need to go for as fast a possible, then do the pressure eval.

Also just ran this through QuickLoad and I would definitely start at the low end working up on this.
