1. I'm going for a swim.
2. I'm going to have a swim.
3. I'm going to take a swim.

I know that you can use 'have' and 'take' with certain nouns, in sentences such as;
1. We're going to (have/take) a look around
2. I'm gonna have a read of this book
I believe they're called Delexical Verbs.
I know they sound a bit unnatural, but are they correct and would you find them okay in informal/casual conversations?
