I am with you and we certainly don't want to wound animals! I always hunt pigs which are fairly small and we hunt the foothills mostly. We try to shoot at 1000 yds or greater if we can, but will take what we get. (Like last week a pig ran out in front of me and stopped to say "hello" and I made a "tremendous shot" at a laser verified 30 yards!!! Yes, it's true!
Anyway, the beam divergence published at a 1000 yds. was ...
Leica 1200 CRF ........1 1/2' tall by 7 1/2' wide
Swarovski Laser guide........... 6' circle
Zeiss monocular.............. 6' tall by 12' wide
This means it is problematic to target the animal only,at that range, even if we could hold that steady...because the beam is larger than the game animal targeted. It would seem to me,( and this is purely hypothetical in my case) looking at that distance , that even with an elk at 1000 yds. a beam that size would be hitting some terrain around the animal. I cannot imagine how hard it would be in the flatlands! 30-338 Thanks for the insight!
