I'm going to call bullshit on this post. I know lifters that have lifted for years that bench sub-300, and these guys dead over 400 and squat over 300. In grade 10 your hormones are still all sideways, and unless you were the biggest motherfucker in the school, there's just no way you were lifting 270, sorry (unless you're talking chest press/pec deck, which doesn't count).
Also, I wanted to comment that size and strength aren't related in any linear sense.
Good lift OP, 330 is an impressive lift. I'm benching 245 2 x 8 at the moment, aiming to hit 265 by the end of February. Eat, lift, sleep, grow.
Bench aside, what's your dead/squat? My bench has always been my weakpoint, but my squat/dead are lethal. Currently deading 425 (2x8), squatting 370 (2x8).
