Is this a normal drinking capacity?

[Bob]

i saw my friend at a party and he was totally wasted... i've never seen him drink before but he was totally whacked out of his mind... he said he pregamed a full bottle of wine.. we are 16.. he is 130-140 pounds id say and 5"10 or 5"11... is this a normal drinking capacity? i dont drink alot and to me he seemed ridiculously drunk for a bottle.... is that alot of alcohol to consume? i dont know alot about this stuff and i was wondering if he overdrank or if he just cant handle his alcohol. also i have no idea how much the alcohol content was but just give me a rough estimate of how much wine a person of his height/age/weight would normally have to consume to be this wasted. thanks alot
also dont give me any crap about underage drinking, i seriusly dont care
