Dan,
You're welcome...it's what we're here for
.
I'm shooting 46 grains of H414 with 120 TSX's. It doesn't fill the case to the neck -- one of the reasons I tried it, because I was running out of case capacity with 4350 and Re 19 before I got the velocities I wanted, and I wanted to try a powder a little slower than Re 15. I have some 47 gr loads, but haven't shot them.
I would shoot any whitetail or mule deer that ever walked with my 120 TSX load, within the range I would shoot a deer with any cartridge. I have killed deer with 87 gr bullets in a .250 Savage, up to 250 gr bullets in a .35 Whelen -- and the .260/120 TSX kills as well as anything and better than some.
And it's light as a wand and doesn't kick enough to bother.
Dennis
