I have no idea what is OP aiming at, but you can imagine, that if that is a semi automatic gun then that is not a sport one. We used pretty much a metal sheet with different shapes in the military services, that when you hit went down. You could not tell if you hit it on the shoulder, on the head or right in the middle though. A system that would have been able to tell this would have given us a better resolution, especially on competitions. On those competitions you do not have time to walk down to the target that is 100-250 meters away from the line-up anyway. If it was a sport system I agree that a paper based target circuit is the best approach. With all my experience I had never ever had real problem with bullets going through the same hole - you can always tell if it had done as the bullet - at least that we used with both air and gun powder rifles - based on lead, so it marked the edge of the hole pretty well. There were once or twice when we had to spend some time to analyse the target to tell, but that's ok. On competitions we used special targets by the way, that has 5 separated circles on it and you shoot once on each - and of course as we entered to the competition we were not expected to as bad as hit the other one :-) Tamas On Tue, Apr 15, 2008 at 11:24 PM, Jinx wrote: > > Several of us have been speculating on how to go about designing > > a target system for a rifle range that did not use paper targets.
