That's a really loaded question... lots of factors in play there, like your target, shooting and weather conditons, cartridge and load.
Off a bench, I can plink steel plates all day at 200yds with my any of my 99s as long as it's not a real windy day. With something like the 45 Colt, 100 yards is reaching just because there is so much bullet drop. On a windy day, those distances shorten considerably.
Out in the field is an entirely different ballgame... from field positions, 40-125 yards depending on the cartridge, target, and weather.
