Recoil pad??? on a 30-06????
Sorry, couldn't resist. My late 60s era Remington still has a metal buttplate which I don't find objectionable, but I don't shoot in just a t shirt either.
I have two with hard plates and I do shoot them in a T shirt. I had a third 06 that had a pad on it so I re-barreled it into a .35 Wehlen. Seemed like a good excuse . Bear
