2 years ago we did a days shooting at the range with two Tikka T3 rifles. One was my 20" stainless 308 CTR in a tactical carbon fibre stock, the other a brand new factory T3 Lite blued. The only thing we did to that was to remove the pressure bedding notch in the barrel channel to have her free floating. Ammo selection is not great where we live but I managed to get a few boxes of 168gr Sako Match. I like ammo with a year stamp in the case head. Groups were shot off the bench, sandbag in the front and rear. Quite light rifle hold. Range 200yds. At the end of the day with all results added we were well under 1MOA. Closer to 1/2MOA.

Is it a good idea in geenral to get rid of that pressure point and let them float?
