I site in at 100yds(taped) and I'm good.
Do you mean you're zero'ed in at 100yds or you just shoot at 100yds?
Also, what's your setup; 12-20ga? Using what ammo?
When you shoot 'good' at 100yds are you benchrested or free-handed?
I will try some shots at a greater distance 125-150yds to see whats happening.
No disrespect but I've been hunting with the same 12ga shotgun for a long time and I still don't think I'd take a 150yd shot at a deer and I practice. Slugs are heavy and you have to practice enough to know where the POI is going to be at different ranges versus where your zeroed at. Course your POI will change shooting uphill or downhill. Only way to really determine that is, again, to practice.
Peezakilla has a good thought with the BOOM,BOOM,BOOM,BOOMBOOM...BOOM,BOOM theory.
All those BOOMs have a projectile attached to them landing somewhere.
Ohio has always been a shotgun state(no rifles) for deer hunting. Although we have to plug our shotguns to hold no more than 3 shells, I just know somewhere there's a law I've not yet read that states "if you pull the trigger once, you have to pull it till shotgun is empty". Soooo... I guess Ohio has the BOOM,BOOM,BOOM theory going on.
Never understood the idea of shooting my deer meat up like that. Course most shots are triple taps so probably 2 out of the 3 were misses. Those slug went somewhere.
IMO, thats more dangerous than using a bolt action rifle.
On the other hand, most shotgun slugs don't have the range of most high powered rifles.
As to whether 'shotguns or rifles are safer'. Guess that would depend on how close the nearest population(house's etc.) was to the hunting area, what kind of terrain the area was, etc...
