BLARG! My brain was fried while editing this video and I made a mistake. The "party trick" method is where you keep the reticle of your scope aimed at the bull's eye, but adjust the turrets over to where the first impact on the paper was. I accidentally said it backwards in the video, so I tried to edit that part out on Youtube, but now it's a little awkward. Sorry friends!

For anyone who doesn't know what maximum point blank range would be.

The projectile leaves the rifle, crosses the optic 'zero' plane... Relatively at close range, travels up a modest amount (potentially several inches) along its arc, levels out in the middle range, and then starts to drop back towards the optic zero plane.
Its trajectory, arc, continues to drop as it moves forward, and it will reach a point where its drop, equals its early rise.

the trajectory curve moves up, comes back down, and drops below the center line.
It is possible to exploit that total rise and drop, within a specific range, and possible to change where your rifle optics will naturally zero to the projectile, where the projectile will be high, how high above your point of aim, and what range you will hit you boot end of that wave.


If you are aiming for a specific known target size. Ie, a 10 inch plate, or an 8 inch diameter vital. Zone.

For an 8 inch target zone. You can accept up to 4 inches rise and up to 4 inches drop.
Outside that, you need to adjust to compensate.

Your Maximum point blank range (for a given rifle/ammo/optic/zero) would be the distances where, you aim dead center, and the trajectory will be expected to deliver the projectile... Within that 8 inch zone.

The tricky part, is that projectile speeds, weights, ballistics, rifle ballistics,
All affect the trajectory. So you won't have identical results from. 2 different rifles.

Then, once you have your individual. Rifle/ammunition/optic trajectory, then you can work with what range you zero your optic, which will change where the bullet trajectory, intersects the optic plane.
You can adjust your MPBR, by adjusting the range you zero the optic.

Thank you for your videos in general, and this one in particular. It's been 50+ years since SE Asia and your video reminds me of some lessons in LRPS.

I figured out the two shot zero technique at what seems like a lifetime ago. I'm glad to see someone else teaching the simple set up. I do use a nonmoving vice for this. Because the slightest bump will make a difference.

Just bore sight at 100 and with your FFP Scope use your reticle and adjust accordingly. I like to use a paper plate on a piece of brown wrapping paper. Did a Ruger American Predator in 2 shots 2 weeks ago at 100.

I have found when bore sighting. An odd shape like a square is hard to get centered in the bore. I found using a wheel on a vehicle is much easier. My niebor parks rite at one hundred yards from the bench in my garage. The round shape of the wheel, with silver center and black tire surround. Makes it much easier to center. I find doing this I am way closer bore sighting. Than with an odd shape.

It will work on a 2nd focal plane scope if there is some kind of reticle with marks. Usually it’s at max magnification or in the case of certain scopes is that there is a triangle on the magnification setting.

[jorgefigueroa]

Jim obviously times have changed, but I remember sighting in at 200 or 2 inches high at 100 on typical hunting rifles. This went on for decades. But what where we shooting, your Classic Remington 700, in a 30-06 or 270. You had a 3x9 Leupold scope Set it and forget it. No turrets to turn or special reticle, it was just a simple cross hair. I still remember many scopes from the 60's that had no turrets to work what so ever. The elevation and windage was done using the bases. Many Weatherby's had those.

I’m a new follower as of a couple days ago, and I have to say dude is absolutely my favorite you tuber. I’ve watched almost every single one of his video. Accurate information, not trying to sell us stuff all the time, just enjoyable content. Keep it up man

The 200 yd zero (maximum point blank zero) is from before there were handy affordable range finders. Dialing your turret for every distance in the field is less practical when you're essentially guessing at the range. It also works well in varied terrain where even a slowly walking animal might be out of sight before you can get your range finder out and dial in the elevation correction.

Also, while the method you're showing is a good one and works well, I wouldn't feel comfortable taking a rifle hunting without following that up with a couple groups shot at 100 and 200 yards.

I just went through 60 rounds trying to sight in my AR with a new Sig 1-6 lpvo today and I got a bad scope. This thing wouldn't hit paper plates at 50 or 20 yards no matter what I did. I even went to 10 yards away and could not hit a paper plate. I bore sighted like you did here with the upper off of it. I would get close, impact was maybe 4 inches to the right so I'd adjust the windage and the impact would not budge. So I'd adjust more clicks and the impact would not move, so I'd adjust it more clicks again and then I was no longer hitting paper and was WAY off to the left. It's like clicking it would not move the crosshairs, then all of a sudden, it would wildly jump way off to the side. I am more accurate with the same rifle with the Holosun red dot on it. My Ruger 10/22 with a beat up old Redfield scope on it is more accurate. My 22 cal pellet rifle is more accurate with the scope that came on it. I have to have a bad scope.

Then I stood up and hit the plate over and over with iron sights on a Mini-14. What in the holy hell? This is the US Army scope and it's junk. Mine slipped through quality control.

Great vid brother. Really good reminder about the sun and shadows.

[dimitristripakis]

Hello, I think a laser bore sighter can help. If you install the device in the barrel and then rotate it 360 degrees, the laser will trace a circle on the target.. Then you mark the center of this trace circle and put the reticle on that. This way you start off with a pretty well sighted scope, without even shooting at all. What do you think of this method?

[rosshall]

I always love long-range trajectory you just got to compensate when you are shorter distance😊😊

[abrowncitizen]

Shot 2, repeat shot 1 because shot 1 was off, repeat shot 2 because 1 was off. Repeat a set of 3 to make sure it was really 1 that was off and not 2. Start shooting hot barrel because trying to figure out if you mounted scope wrong. Repeat steps 1- 20 and grab another box of ammo. Finally try 3 final shots on warmish barrel to make sure your on target.

[jonathanmitchell]

We just use 200meters to check the elevation of the 200 meter zero. It ends up being about 2, 5 inches high at 100meters, depending on load and cartridge. fine adjustments are made at 100 meters.

But.. I only hunt with my rifle using a simple duplex retical, and no shots over 300 meters. (maybe once or twice)

[Hunter-vlft]

I use 1/4" graph paper. 1 shot, then count the squares and adjust scope. Verify with 2 more shots, done.

I was helping a guy zero his hunting rifle/scope and after two consistent rounds he'd make an adjustment. However his next shot was totally off based on the adjustment. I finally looked down hi scope and it turns out his parallax was way off. I could move my head and get the crosshairs to point pretty much anywhere I wanted. Every time he got off the gun he had a new sight picture. We adjusted the parallax and things settled down.

[JohnSanders-po]

As former welder i know for sure the best way that doesnt matter!!
Only flat ground like this is flatter than hills like further north west!?
Balstic probability of firing two shots to zero ANY rifle is marginally better than butter.

[danarenodano]

I just got a new sig cross 6.5 and was having trouble zeroing it. This is my first rifle with a scope. I Saw you video yesterday, went out today and tried out what you did in the video. You should rename the video to 1 shot zero! Thanks man
