Im not talking about having the reticle at 45 degrees. I said that this must be vertical and the bubble level that you permanently on your gun keeps this vertical. so when you wind on or off elevation it keeps it in the vertical plane. However which way the action points under it is irrelevant. The rifle for all intensive purposes is round it doesn’t matter which way the stock is pointing.
The gunsmith may have indexed the barrel to get the natural bend of the rifle to be in the vertical so it is more easily disguised in the drop. But that bend is constant and can also be compensated by windage adjustment. The only purpose of the stock is for holding the action and most importantly managing the recoil to keep that to a minimum and parallel with the barrel. Not kicking up or sideways like some designs do.
