180 to 200 grain bullets in a 300 makes more sense........
THANKYOU!!!!!! this is exactly what i needed!
so ive got some exploratory loads from 71-75 grains in 1 grain steps, barnes says COAL is 3.340. Ive got about3.550 to where the bullet touches the rifleing. does that seem like a long distance for the bullet to jump?

You may have the play with the seating depths with the TSX, they recommend .030 to .070 off the lands, start at .050, or whatever your max magazine length is...
Rule of thumb is the neck contact on the bullet = 2/3 x bullet diameter minimum. Which with the .308 = .203" of the bullet in the neck, don't seat further out than that.

I'm loading the 150 TSX to the teeth with RL-19 (79.0 grs). Surprisingly, I got about 30 fps more than with a book max load of RL-22. At OAL of 3.340" and a CCI250 primer, these things are holes in holes at 100 yds leaving the muzzle at 3350 fps. And a 150 TSX .30 bullet at that speed will kill most anything - thru and thru on a 609 lasered yards cow elk that weighed about 650 lbs this fall, thru a rib in and thru one out, golf ball sized hole right thru the lungs. Phenomenal accuracy.
