I had an error in my original post-the berms are not 20 feet high but substantially less than that. The berm at the 100 yard target frame was reported to be 4 1/2 feet high and the ground surface between the 100 and 200 yard targets slopes upward slightly. After hearing this report last night, I would be concerned about ricochets beyond the range, but it seems to me that any bullet type has the potential to ricochet; if the bullet strikes ground surfaces at a shallow angle I think the physics of this dictate that it very well may ricochet, even hollow points as the strike is on the side of the bullet and not at the deformable hollow point. After hearing this report last night, I think that perhaps the rifle range needs to be closed until the situation is corrected. It doesn't make any sense to me to ban FMJ ammo, allow shooting of all other types of bullets and think that the ricochet issue is solved.
Am I missing something here? I would like to hear opinions from those of you with experience in ballistics or experiences with ricochet problems at outdoor ranges.
