Wadcutter
Also: WC
A flat-nosed bullet that cuts a clean, scoreable hole in paper targets. Common in target pistol; rare in centerfire rifle.
The flat or slightly-cupped nose punches a sharp-edged circle through paper, making bullseye scoring unambiguous. The trade is a low ballistic coefficient, since that blunt nose sheds speed quickly. Wadcutters work best as subsonic, short-range bullets.
In rifle precision, you mostly see wadcutters in .22 LR competition and some specialty bullseye loads. Most rifle bullets use spitzer-boat-tail shapes built for distance, not for clean paper scoring.
