I'm only 61 and I sincerely hope that 11 years from now, I'll still have the energy and open mindedness you demonstrate.
While I do carry a LRF when out hunting, I seldom used it in a big game shot itself. Most of the time I would RF specific points and draw a "map" of distances.
For small game, the use of a coplanar and parallel to the LOS laser dot was much faster and easier.
AND completely applicable in the field, regardless of the different target sizes (real pests do not have a standard Kill Zone painted, nor are they standing on standard pavers or other bases
With more current technology, some LRF scopes are quite applicable to airguns.
So, I would humbly suggest we consider the use of "laser devices", more than the narrow LRF concept.
I would also still maintain that shooters using "laser devices" should be allowed less time to take their shots. Don't know if half the time is the correct number or not, but less time seems logical.
As current practice is, anyway, the top Hunter shooters usually have quite some time left when they are done.
Thanks for reading, keep well and shoot straight.
