Narrative:

After fueling and preflight I taxied out and accomplished a normal run-up. I leaned for best power at 1800 RPM and enriched mixture slightly for full power setting. Mag check was normal at 100 drop on both magnetos. After completing before takeoff checklist for a flap 10 takeoff I initiated the takeoff roll. The engine indications were 23 inches manifold pressure and 2500 RPM; the normal static RPM for this airplane. The aircraft accelerated normally to about 60 mph. At around 60 the acceleration rate seemed to slow. I looked at the RPM which had decayed slightly to 2450. I pushed/turned the prop control to check that it hadn't backed out and got a slight increase in RPM. By now I should have had 2600 RPM but still had slightly less than 2500. With less than [half] of the runway remaining I had to decide to abort or continue the takeoff. There was a small berm at the end of the runway which I did not want to hit if I aborted. Since we were at a lower altitude than my home airport and the airplane seemed like it wanted to fly I elected to continue. There was a slight rise at the end of the runway and the airplane would neither accelerate nor climb above it. The airplane touched down at about 50 mph on the slope with the airspeed decaying. The touchdown was uneventful and we decelerated to a near stop. We then stopped abruptly and the airplane started to nose over but then settled back down. The engine was stopped. I asked my passenger if he was ok and we both agreed we were ok. After assessing that there was no smoke or fire I secured the mixture; fuel; magnetos; battery and other shutdown items. We both exited the airplane and checked to see what had happened. It appeared that the airplane had hit a section of partially buried railroad ties. The nose wheel was sheared off and there was some visible damage to the right side of the cowling and the nose gear doors as well as one of the prop blades being bent. The rest of the aircraft seemed intact.
