It seems like we see a thread a day on ethics and extended range shots in the hunting world and if your looking for a hot topic for discussion just post up a thread about the subject.

There is no denying that technology and the current availability of top end equipment has made extending ones effective distance on game more possible than ever before.. unfortunately what gets missed by main stream advertising and retailers is that hunters still need to be educated on the use of these products and how to effectively practice with them to take advantage of their uses and establish their own (MER) maximum effective range and become a more effective and successful hunter.

Now when people hear the word maximum they initially envision shots of 1000 yards and beyond...but this is not the case at all. Maximum effective range is simply the maximum range that each of us as hunters needs to establish and use as a bench mark in our hunting adventures.

For some this may be 200 yards for others it may be 1000 there are a ton of things that go into developing and utilizing MER in our shooting and they include but are certainly not limited to the following...

Education (necessary in understanding your equipment and skill level)
Equipment ( knowing your equipment its' limitations and how it actually works)
Practice ( not only shooting but shooting in filed conditions and at targets that mimic the vital zone of the animals you plan on hunting at the distances you plan on hunting)

Self evaluation (this is where a lot of people fail...you need to be man or woman enough to understand what your limitations are based on the above items and then have the backbone to stick to it in the field. Just because you choose to shoot a caliber capable of taking game at extended ranges doesn't mean you have the skills or knowledge to do so!!

The importance of establishing a realistic and confident MER is immeasurable...a hunter that understands what his or her limitations in the field are is a hunter that is setting themselves up for success and greatly reducing the chance of unfavorable results based on poor decision making and or lack of knowledge about either their skill set or equipment.

MER is very personal and cannot be established by others and for others it needs to be done by the hunter themselves.

Understanding your MER is just another tool in a complete hunters tool box that they can rely on when it comes to making sound decisions in the field and being successful. Its not a question of how far can I shoot? its a question of how far can I effectively harvest game...in field conditions and being able to incorporate that distance for use in the field.

Great article. I now my own MER that's for sure. In 2012 I made my longest ever kill. It was an antelope and was 471 yards, one shot kill. Elk maybe a little longer, a lot longer if it was an elephant! LOL. I am 72 and I am sure it will never get longer only shorter as I get older and I start to wear out more than I already have. I can hit targets at 1000, but I'll never hunt at anything close to that.

Its a very good point about each person having their own MER. I don't think many people think of it that way. I know my MER is hanging right around 300-350 yards depending on conditions such as what I am chasing and wind. For some, 300 yards is a slam dunk, for me its more of a jump shot :)

Great post! It seems a lot of the poorly written articles today are written by those who try to place there MER's on others or think that those who have longer MER's are unethical. In addition just wanted to say all of your posts about long range shooting are great! You know your stuff.

Great Post! Made me think. My longest shot to date was at a little over 425. When I took that shot 3 years ago it was absolutly at my max comfort range. Since then I have practiced more at long range and now feel 450 to 500 is my MER.

I read about MER about 20 years ago but they called it "maximum point blank range" . For me and my rifle which is a 7mm mag and the 150 grain bullets I usually shoot that was 416 yards. I know this rifle will shoot much farther but I use an old fashioned Leuopold scope with
plain cross hairs, no long range stuff. So I'm not comfortable trying to aim high if I think the animal is farther than that. I know out to that range I can aim "on hair" and this has worked for me since 1980 when I bought my rifle. My longest shot ever was just over 400 yards. If i's further than that I either try to get closer or it's just too far for me.

You're mixing things up when you say the two are the same. The latter is when you sight in for so many inches high at a certain distance, usually 100 yards, and then based on the ballistics for that cartridge there is a distance where the bullet will be dead on and then out at a further point it will drop below the zero and be the number of inches low that it was high at 100 yards. That longer distance is what you remember from 20 years ago. The MER we are talking about has nothing to do with that, but rather how far out each individual person is comfortable shooting with their particular setup and skill level. The rifle you mentioned is capable of very long shots with the latest scopes that are made for a particular bullet's ballistics and then can be dialed up to a known long distance after using a range finder such that the reticle stays right on the vitals even though the bullet trajectory is many feet above that. That takes the guess work out of hold the reticle in an older scope way above the animal at real long distances. By doing like you mentioned with your older scope out at 400 yards and holding on the backbone you are allowing for the drop the bullet will have at that distance and still hit the vitals of an animal with say a chest that is 18" top to bottom.
 
As previously stated by many, maximum effective range has many variables and is highly individualistic. It's up to the person if they can make that high percentage kill shot on a game animal that they are presented. Just know your weapon and your capabilities and go from there. Exception, coyotes(!), if I can see 'em they're in range.
