Ive always been taught not to put my left thumb on the barrel when shooting as this effects accuracy -Never understood why.
The scope is fixed firmly to the action and when zeroed both scope and rifle are pointing at the same place. The barrel cannot move or flex regardless of how much pressure you exert on it.
When I had a Pro Hunter, the stock seemed to be made of flexiboard but it shot superbly., with or with bipod attached.
I recently stuffed my action 1 Sako into an action 3 composite stock that I had roughly power filed to size and still it shot 1/4inch at 100 yards without re-zeroing.
Can someone please explain it.
