300 kg for 12 reps
Estimated one-rep max: about 407 kg (896 lb). The five formulas span 385–432 kg, so treat it as a range rather than a number.

So is 407 kg a good bench press?
If that lift is a bench press, 407 kg (896 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.

300 kg × 12 — common questions
What is my one-rep max if I lift 300 kg for 12 reps?
About 407 kg (896 lb), taken as the mean of the Epley, Brzycki, Lombardi, O'Conner and Mayhew formulas. Individually they give 385 to 432 kg, so the range is the honest answer — and above ten reps all five are extrapolating past the data they were fitted on.
Is 407 kg a good bench press?
If the lift is a bench press, 407 kg (896 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 163 kg × 5, 224 kg × 5, 285 kg × 3, 325 kg × 2, 366 kg × 1, then the working single at 407 kg. It is a conventional ladder rather than a rule; the test is that the last warm-up still moves fast.
