You have the school Jordan to start driving home maximum effective distance terminology vice "long-range" to include instruction on how to determine those limits. Thankfully Applied Ballistics, via Bryan, is developing a field program (WEZ) to help one determine confidence or hit probability in the field. Confidence limits are a great method for education. I shot an elk at 900 yards can have many meanings. Making hunting posts such as 900 yards with a confidence of 98% including the conditions is different than 900 yards with several shots, most certainly due to low confidence limits. Instructing and harvesting animals within high confidence limits, or maximum effective range, will drive home the message. We can take the lead by setting this example.
A term those of us who are former or active military which we used extensively in training is, "Maximum Effective Range", which generally was the limits a given weapon or weapons system had for consistent accuracy, and an effective, clean kill.
It also incorporated the skill level of the shooter. Since that term has been around for decades and so many of us in the LR and sniper communities are former military we could just agree to stick with that so we're not complicating the vocabulary.
One thing that we have a hard time with is simply convincing people that we're not just jerking their chains when we're talking in a lot of cases rather glibly about 600yds just being a chip shot and a thousand yards consistently doable. Most folks simply are not willing to accept that you can do something they cannot and if they have convinced themselves that 300yds is extremely long range the only way to convince them otherwise is to offer to show them and help them to make a few shots at ranges they simply didn't formerly accept as even being possible.
To that end it's up to us to reach out when we're out shooting and someone becomes interested in our rigs, rounds, scopes etc to welcome them on over, engage them in conversation and if they want to try a shot or two let them.
I've done this with pretty much all of my friends and many of my clients and its' extremely rewarding to see their faces light up when you coach them through what you are doing, they see the shot made, and then to see them really light up when you succeed at helping them make a shot or two.
My brother's kid Jimmy is very much a city boy but his dad grew up on the ranch and I taught him to shoot and shoot well beyond 300 yds many years ago.
Last year for the first time Jimmy came along with us and we ere busting rocks from 400-750 and of course he actually put down his electronic game and got interested so in a few minutes I had him doing the same thing with the .264, then the 300wm, then the 7stw and then even the 300Rum.
We didn't even tell him how far he was shooting but he was doing well with near misses and good first shot hits and it didn't take long for the apprehensive teenager to be taking those shots with confidence and getting hits even out to 880yds.
When we got done we told him what calibers he was shooting and the ranges at which each of the targets was and he was utterly floored.
Needless to say the hook was set for life all in about an hour and he got to go back to school and brag about his accomplishments. Of course he had half a dozen friends begging to come out next time they headed out my way hoping they too would get a chance to try it themselves.
We are ambassadors for our sport everywhere we go and the best way to ensure we can keep enjoying our sport is to be good ambassadors.
