Too many wounded deer running the woods or laying dead because of hunters using faulty equipment. A hunter needs to insure that the gun/bow shoots where it is susposed to. If the shotgun will shoot out to 50 yds and be 1-2 inches low then maybe I'd use it and limit my shots to that range. Not ethical to shoot beyond the ability to hit where you aim.
Don't get me wrong, I'm not saying to use faulty equipment.
Just knowing where the gun shoots consistently, and its shooting low a few inches, it would be doable.
I'm all about ethics.
With my bow a few years back, I could not get a decent group.
So, I stopped and shot the same arrow repeatedly till it was dialed in. Switched to a different arrow and I was off four inches?
Same batch of arrows, same brand, everything.
So I labeled each arrow 1 thru 6, and shot each one repeatedly, till I knew exactly
where each one shot. Never readjusted the sights. Some went a touch left, right, up or down.
By knowing my gear I was deadly accurate with each arrow. And my season was good.
Same thing applies here, know your equipment.
If the OP can get his scope fixed, great.
If not, he can still hunt knowing the guns characteristics.
