So is 318 lb a good bench press?
If that lift is a bench press, 318 lb (144 kg) puts a man at 82.5–87.5 kg bodyweight at the 75th percentile of 29,914 judged competition benches — advanced. For a squat or a deadlift the same weight ranks lower, because those lifts are heavier for everyone.

275 lb × 5 — common questions
What is my one-rep max if I lift 275 lb for 5 reps?
About 318 lb (144 kg), taken as the mean of the Epley, Brzycki, Lombardi, O'Conner and Mayhew formulas. Individually they give 309 to 327 lb, so the range is the honest answer.
Is 318 lb a good bench press?
If the lift is a bench press, 318 lb (144 kg) puts a man at 82.5–87.5 kg bodyweight at the 75th percentile of 29,914 judged competition benches — advanced. That population all competed, so it is stronger than a gym average.
What should I warm up with?
The ramp below runs 127 lb × 5, 175 lb × 5, 223 lb × 3, 254 lb × 2, 286 lb × 1, then the working single at 318 lb. It is a conventional ladder rather than a rule; the test is that the last warm-up still moves fast.
