Personal experience includes deer to 40+ yards, near dark in woods, offhand. With improved conditions, full daylight, solid rest and options for additional shots, limitation is hunter not gun related. No full metal jacket round nose bullets, the extra penetration just isn't needed nor frequently legal. Any +P 45 ACP designated soft point or jacketed hollow point for small deer. I like 200 grain Speer Gold Dot, cheap, effective. Hornady XTP 200 grain also an option. Personal defense bullets work on deer but tend to fragment so are better limited to broad side lung shots.
