On an elk. I am practicing at longer ranges, out to 30 yards. I'm making progress but I would like to have some  hunting related reference to judge my groups. So, what is the size of the kill zone (heart/lung area) of the elk? I know the size of a deer, but I also know that my groups aren't that tight. Don't worry guys, I won't be going after elk with marginal skill levels, I just want a game related reference point.

Depends on the elk....12 to 18 " covers the heart/lung area on most so I would practice for 6 to 8 inches out to 40 yards with a good heavy bow. Closer and tighter with a lighter bow.

Google elk archery kill zone ... lots of info

Well, I'm doing the 12 to 18" most of the time, but I still have some work to do for 6 to 8" groups. Also, no interest in 40 yard range, but 30 is still tough enough. I essentially only hunt deer and am comfortable keeping to about 20 yard shots. The longer range interest is more for 3D than actual field application. 4dogs, are you proficient out to 40 yards? If so, how long did it take to get your shot grooved at that distance? I have discovered several flaws that really stand out at longer range. I have a poor release that I am diligently working on with a modicum of success, but sometimes it seems that, as I release, my bow arm swings slightly to the left (right handed shooter). Combine that with plucking the string, and who knows where it may hit? Actually, it is not quite as bad as it sounds, but it sure is giving me a lot to work on during lockdown. Due to health concerns, I am not getting out of quarantine yet, so there is still time to perfect it. I have found that it is easier to work on form with a lighter bow, so my 40# Hill Cheetah is getting lots of exercise. Perhaps it will become my 3D choice and maybe some use come hunting season.

Well..I have never killed an elk at 40 but I do practice out to 50 and do well. For me I have a lot  easier time at 30 and under when I have my long shot working. Everything would have to be just so for me to take a 40 yard shot at an elk and things just never seem to work that way    I think the most important thing is shoot the heaviest bow you can handle well, know what your limitations are and learn how to hunt them to your advantage...Elk hunting is 90 percent hunting...10 percent shooting.

Sam..I sent you a P.M.

I buy this.  When I take the time to practice beyond my maximum hunting range I shoot better within that range.  If your maximum target shot is your maximum hunting shot, it will feel that way when the moment of truth arises.  If, on the other hand, your maximum hunting shot is well within your target range, you will have greater confidence when it is time to release an arrow.

A am pretty sure there are pictures own the shot placement forum.

3 times bigger than a 90 pound whitetail doe.

Generally around the size of  a men's basketball.   The hide on a big bull will surprise you how thick it is.
