Well. The MOST obvious thing wrong with driving the screw home with a hammer is that 10 oz is too light of a hammer—you’re working way too hard. Lovely hammer, but not for this. Silly man, if you’re gonna hammer corrugated nails, use a framing hammer. Sheesh.
But—given the tools at hand—definitely set it with the hammer and then screw it home with the screw gun.
To Philippe—with a relatively long and thin self-tapping panhead screw to affix thin ply, you don’t need a clearance hole. The ply won’t split, and the larger threadcount in the substrate overcomes the resistance of the 1/4” of ply, and draws it tight. If it’s a stouter or flathead screw, or thicker stock, or plain wood stock .. drill the clearance hole.
