Hi, a first post for me, so be kind.
I was talking to a lad who is far more familiar with rifles than I. I mentioned I have a Sako 75 .243, and my father a Tikka T3 .243, and that we both use 100 grain factory ammo, me Federal Premium, and my father RWS. He told me that Tikka T3's don't group so well with the 100 grain stuff due to the rate of twist in the barrels. I recall he wasn't so sure about how or if this was applicable to my Sako.
Any comments on this ?
