If i am 160 5'9 bench 145 from 15 to 20 times and max out at 200 1 time.how much would i be benching in about 2 months?

I am 205 and can bench in the mid 300lbs range. If you want to lift a lot you must train with a lot. 5 or 6 sets of 6 and less. And a crap load of protein is also a key factor. I went from 225 to 305 in 5 mths.
