For me...
I usually take at least 2 handguns in different calibers. 45acp & 40sw, at minimum of 100 rds, max would be 150.
9mm & 22lr would be minimum of 100 rds and max of 200.
12 gauge would be minimum of 3 boxes of birdshot and a box of slugs or 00 buck.
9mm carbines would be minimum 100 rds and max of 200.

My range sessions have never lasted more than 2.5 hrs - even though we are at an private outdoor range.
I'm there to practice...and sometimes to help teach friends and family members the basics.
I do socialize from time to time, but that's not my sole purpose of being there.

And I do have a buddy of mine from work who can make a 20rd box of .223 and a 50rd box of 9mm last 2 range sessions.
He says he's just patient and goes at a slower pace.
I just say "you aren't patient - you are just plain ole cheap".
