If your trying to duplicate extreme longrange hunting, the one shot situation is probaly not a real good idea.
Many shooters would NEVER get on a steel plate.
We would be there for hunting duplication and fun shooting and to show those who have not done a lot of Ultra LR shooting what can be accomplished
Most LR shooters trying to hit something in a hunting situation at 1500 to 2000 would not do so if it was just with one shot and not shooting a sighter or two.
I wouldn't shoot at an animal knowing I may not place that bullet into him with a killing shot the first time and taking only one shot at him at that range.
There are just two many obsticles to overcome when shooting for 1 st round hits past 1000 yards. Up to 1000 yards it's a pretty safe bet that you can make the hit, but after that conditions change rapidly and it seems a spotter shot is the way to go to eleminate a wounded animal senerio.
There are very few shooters/hunters in the World that would honstly try 1 shot hits at 1500 to 2000 yards day after day, in new uncharted areas.
If someone has tried an area and shot it recently, they may have a handle on the 1st shot kill if the range and wind were known in advance.
This is not the case at Rics place or the real world of ultra longrange hunting.
Maybe out to 1000 yards would be the 1 shot aveneue to consider. After that sighters to be shot away from the steel.
Repeatability of your rifle is important too. It's nice to see (after you are on target) how many times in a row you can hit the steel plate at extended range. It will show you what your rifle is capable of doing and how well it holds on target.
Just my thoughts.
