I tried to stay out of this, but it wouldn't stop. I guess I might as well chip in to the "discussion."
Generally safe hearing levels can be [sic] still be attained by the use of a sound suppressor even with supersonic bullets.
<rant>Generally safe? Who are you to tell me what is safe for my ears? How much hearing is lost at the "generally safe" level?
Hearing protection is not the only reason to try to have the shot as quiet as possible. In my particular case there are several reasons to have my gun as quiet as possible and I don't need to justify or list them for your approval.
Also, your generally safe ambiguous-ness leads to how many shots can be shot and still be safe? I like to shoot with my deer load, more than once, at before going into the woods. Is my hearing generally safe after 2 shots? 3? 10? How many?
I have some young kids I would like to sit in the stand with me in the coming years. Is this "generally safe" level safe enough for young kids? Are you going to now tell me how unethical it is to take a kid into a tree stand with me?</rant>
There is no need to go subsonic
No need? Says who? You and Barack going to dictate to me what I need now?
and is ethically very questionable for deer hunting, especially at 200 yards.
<rant>Who are you to tell me what is ethically questionable? What defines ethical in this instance any way? Does PETA determine what is ethical? Deer have to die in 10 seconds, 12 seconds, 30 seconds, 5 minutes or what? You can make unethical shots at 20 yards with a full powered 30-06 as well. You are assuming poor bullet placement by questioning how ethical it is. With proper bullet placement with a correctly set up gun the deer will be "ethically" killed, by my definition.</rant>
It is unethical to cause undue suffering in any animal.
<rant>What is undue suffering? (See rants above.) I guess it boils down to who do you think you are to question someone in a situation you barely know anything about as if you are the "Decider of Ethics in Hunting"? Right now, I typically hunt with a full powered .308 and have never taken a shot over ~160 yards. Even though I am very confident I could easily make a clean kill on a deer out to at least 300. In my life I have never missed or wounded a deer and I don't want you dictating your ethics to me.
I did not post here to learn about your ethical mores. I just wanted to know what sub-sonic, suppressed rifle would take a deer at 200 yards or less. If there is nothing out there that can make a clean kill at 200 then I might need to shorten the distance some, which is fine, but I think a suppressed subsonic round can make a clean kill at 200 yards.</rant>
