A couple of years ago I gave up on obtaining any respectable accuracy with the 140gr TSX in a tang safety Ruger M77 1-8 3/4" ROT, but now, taking a second look at the TSX and a new look at the TTSX.
Powders I used with the TSX are H-414, H4350, RL 19, RL 22 and H4895.
Primer was CCI200 and Remington cases.
Bullet seating depths were from .30 to .90.
100yard 3 shot groups were 2" to 3 1/2".
The Ruger is capable of good accuracy with certain bullets.
1" 100yds 160gr Partition and Hornady 154gr
7/8" 100yds 115gr Speer HP
3/4" 100yds 145gr Speer Hot-Cor (50grs H4350 bullet crimped with Lee crimping die)
Will be loading the TTSX in the next few days so would like to hear your experience with the Barnes in the 7x57.
