315 for 10 is good. If you want 405 though train for limit strength. Take one day a week and instead of 10 reps w/315 do 2 then do 1 rep with 365 and so on stick to singles till you get to near 405 and do this for several weeks. Another thing you can do is to take say 350 and press it for one rep, rest one minute then press it for one agin. do this till you can no longer press it. should be close to 6 or 8 reps. the next week see how many times in a row you can press the 350.
This is how I trained to a natural 445 bench at 6'2 225#'s bw. I repped 315 for 12 at 3 sets during this time as well.
Another great workout is close grip benches on an off day. treat it the same way as the bench, go as friggin' heavy as you can every single time once per week.
I was able to rep 365 for a few in the close grip during this time as well.
It all boils down to what type of strength your after.
Pressing 315 for 10 is really good though and can really pack on the mass if you can get up to 3 sets like this.
