One of the guys in my gym is a world champ powerlifter but I've only seen him pick up 300 pounds. A lot of us are much lighter than the average American male so a more personal goal might be twice bodyweight.
Are you sure you don't mean kilos? There is no weightclass + lift combo where 300 pounds would be world-class for a male, as far as I can tell, except for the snatch at the lowest weight class (56kg)
Well I posted this because I didn't want some 120lbs kid injuring himself trying to get to 4 plates by the end of the year. But people love to nitpick and argue about powerlifting online.
The guy pulled 400 something at 123lbs, but he just does 3 plates these days.
