1. I would not change a rifle to use TSX bullets unless I had to by law.
2. I would not spend on a 7mm RM what with that cartridges reputation for pressure spikes.
3. I would not spend on a 700 design but instead trade it for another rifle.
However stuff like throat reamers are just nickel and dime things as compared to the universe. If doing it motivates you to shoot and hunt more then do it.
