Thread: what modifications

for reference, Im wanting to setup my tikka t3x 300WM, average 500M max shots and would like to give it the best possible base to do so without going to overboard on budget.

I already have a DPT long range chassis, EGW 20 moa rail, tier one rings. Have ordered a titanium recoil lug and a lighter trigger spring.

And before I send it to the gunsmith, Id like to make sure i get what else I need before sending it in.
