This can be tricky because not all vest are the same,vest that cops use can usually be pierced by medium caliber rifles like a 30-30 or AK-47 or high caliber hand guns like .44 mag, but the dragon armor as they call it they some times use in the army can withstand a 50 caliber rifle,the most powerful rifle every made beside armor piercing rounds,but funny enough a 22 mag can pierce a normal vest,even though its not very powerful if its a full copper jacket it can pierce,thats because its such a small bullet that it does not take as much power to pierce objects as a large 45 caliber or 50 caliber would.
