I wouldnt be thinking about custom work yet. The trigger on a Tikka T3 is great. I havea Tikka T3 Lite Stainless300 WSM with a Nikon Buckmasters 3x-9x on it. This is a 3 shot group at 200 yards from when i was checking my sights after bear season. This was the last of a box of ammo or i would have done a 5 shot group. Also this is Winchester Super-X 180gr Power Points.
