Just like MarkCo, I shoot to 200 yards with every handgun now and then.
I own a firing range that goes to 300, so I can do it easily. I can walk down my hill to public ground and shoot rifles to 600 on the same range.
But most of my handgun practice with autos (9mm and 45ACP) is done at 20 yards, and most of my practice with revolvers (357 mag, 44 mag and 454 Casull ) is done at 75 yards.
My reason is simple.
I carry revolvers as "field guns" and I hunt with them fairly often, not to mention that when I am out on my land and I see a coyote, fox, skunk or any such varmint, it's seldom closer then 50 yards. I zero my 357s and my 44s at 50 yards, and at 75 the hold is very close to the same. I zero my 454 at 75 yards dead on.
I carry autos as "town guns" and the idea for them is mostly personal protection. They are all zeroed at 20 dead on.
