So is 304 kg a good bench press?
If that lift is a bench press, 304 kg (671 lb) puts a man at 82.5–87.5 kg bodyweight at the 99th percentile of 29,914 judged competition benches — world-class. For a squat or a deadlift the same weight ranks lower, because those lifts are heavier for everyone.

270 kg × 4 — common questions
What is my one-rep max if I lift 270 kg for 4 reps?
About 304 kg (671 lb), taken as the mean of the Epley, Brzycki, Lombardi, O'Conner and Mayhew formulas. Individually they give 295 to 315 kg, so the range is the honest answer.
Is 304 kg a good bench press?
If the lift is a bench press, 304 kg (671 lb) puts a man at 82.5–87.5 kg bodyweight at the 99th percentile of 29,914 judged competition benches — world-class. That population all competed, so it is stronger than a gym average.
What should I warm up with?
The ramp below runs 122 kg × 5, 167 kg × 5, 213 kg × 3, 244 kg × 2, 274 kg × 1, then the working single at 304 kg. It is a conventional ladder rather than a rule; the test is that the last warm-up still moves fast.
