I ONLY buy Tikka Factory Rifles now, so I just need to replace, the Trigger Spring with one from, Elay Precision, YoDave or Ernie the Gunsmith.
I have put, Timney $ 230.00 Triggers on, my Rem 700's tho.
On ALL my New Rifles, I do, the Triggers,.. FIRST
Hunting pull weight, a CRISP, 2.5 to 3 Pounds,. Varmint & Target shooting a CRISP,..1.0 to 1.5 Pounds.
Then mount scopes,.. Lap / Loctite, etc.
I check, barrel "Free Float" clearance when putting in, the Trig Spring on my Tikka's.
Next I start Bbl Break-in and working up, loads.
Then Bedding,.. "if" necessary.
