My left ear thanks you.

Thank you for explaining this in simple terms. I have been shooting the point blank method for more than 30 years. I have tried to explain this to friends and family members and failed miserably, some of my conversations have turned into very mild disagreements. I run into the same mindset over and over again that individual’s don’t understand this method and as a result are not using their firearm to it’s potential while hunting big game. To many try to figure hold under or hold over when making their shots resulting in a miss at what they are shooting at. Well done!!!

Ive always been told the 50 yd zero was the best for a law enforcement patrol rifle but was never explained why. This video really put it in perspective. Great job Jeff.

Finally, a true expert that starts with Target Size otherwise known as Vital Area and Scope HOB. The Danger Space is the distance the bullet travels within the target size. I describe it as the distance a bullet would enter a pipe and exit without hitting the sides. The Danger Space for a typical 5.56 or 7.62 is approximately 300 yards with a 200 yd zero and 3 inch HOB.. Thanks so much. Shoot and figure it out than print out and laminate a Range Card.

I, am 65 years old. I have hunted for over 50 of those. In all those years, I have never heard anyone explain that anywhere near as good as you did, no matter how much time they took. good job!

Thanks for the kind words and feedback. I'm really glad that was helpful. Have a good one.

Jeff is exactly correct in stating that you must know your target first or set your target size first. Example: if you are hunting deer and want a 4" target then your point blank range will be the range from zero yard to xx yards that will guarantee every shot will be inside the 4" circle (not counting wind drift) when the crosshairs are on the center of the circle when the guns trigger is activated. A mans head is approx 8" in diameter.

This is explained as good or better than I've ever seen - well done. I'm an old 4th award rifle expert in the Corps and admit to not really understanding point blank range. Now I've got to figure out PBR for a 45-70. ;)

Great Job, explaining this stuff for simple people like me. Thanks I learned some stuff tonight. GOD BLESS YOU! Thanks for your service.

Awesome video Jeff. Nicely done dude.

Thanks for the clear, simple explanation. I've used the 50yd/200yd (5.56) method since 200yds is close to the max I would need but I can still do holdovers if needed. For 300AAC I use a 75yd zero and adjust hold from there. It's used mostly for closer in hunting. I use a variety of optics but all my zeros are the same so whatever I pick up I know what to expect. Count me as a new subscriber.

outstanding presentation. look forward to some range time.

Thanks for sharing this excellent lesson!

Excellent, many thanks!

THIS. THIS one is the best video on this topic I've yet to see. :-)

Well explained. Thanks.

I always sight my 270 Winchester 3-31/2 inches high at 100 yards with a 130 grain bullet, puts it 4 inches high at 200 yards, back on target 325, 9 inches low at 400, 25 inches low at 500

Thank you sir sometimes the k.i.s.s method of explaining is perfect for most .👍

Well done, professor...

Very clear thank you

Great instruction!

Very good. Thanks

Excellent video and excellent information. Easy to understand. For most shooters any zero will work (ie ... 25, 50, 100, 200, etc...) However, once you have chosen your zero, then you should actually go out and shoot a lot of rounds, at different distances, to get comfortable with your choice. Too many new shoots think that once they have a zero it means they can hit any target at any distance without any other thought. Hold-over and hold-under will come into play at some point and this is what you need to be familiar with. There is no "magic" zero. Set a zero, practice with it (a lot) and get familiar with judging the distance to your target.

Excellent!

Thank you

Thanks

Hey Jeff, what are you concealing there on your right hand side? A desert eagle .50? That looks too big to be a Sig 226.

If you are selecting a zero for a specific type of weapon, a specific mission, specific hunt, etc... then consider your potential target and engagement range. For example, with a SBR, you probably shouldn't choose a 300m zero. If you are using a short barrel rifle then you probably expect to engage targets at 100m and under, so set your zero accordingly. Then go out an practice with the zero you have chosen. Take multiple shots at 25, 50, 75, 100, 200, etc... make notes of your hold over or hold under so if you ever need to use that weapon you will not be surprised when you shots are 2" low up close.

Please don't tell my wife that the circle he drew is what 8" looks like, holy shit.

Hey Jeff, quick question. While researching zeros for a 14.5inch barrel I came across a 40/250 yard zero. What struck me was the total vertical deviation was 7inches out to 300 yards with a max ordinate of 3 inches around 150 yards and 4 inches low at 300. Have you heard of this zero? What would be your opinion of this zero sir?

Big Thumb Up, Jeff. You have simplified what can quickly evolve into a Graduate Course Level discussion. Is the goal to engage your target with a kill shot? Or, to punch a hole into a piece of paper? Oh, yea. I'm a retired Army Infantryman, Vietnam-Era.

@@TridentConcepts my area in Alaska has a lottery and is not very well used. A few years ago, fish and game approached me and asked if I had noticed a lot of browsing. The area along our roads looked like a bulldozer had been through. I told them about what I had seen and they had counted a large number of moose, higher than usual. They complimented my community in a large meeting thanking us for our conservation efforts (we've been clearing lands of invasive trees and replacing these areas with willow, Alaskan Alder and birch since 1990). The population was so large we've be allowed to take "Any" moose for 2 years. This is in the Beluga/Tyonek area on the west side of Cook Inlet. Part of conservation was introducing a specially hunt for the "Wounded Warriors" program. We set up stands with ramp access and brought in bowhunters, handgun and rifle hunters. It was a 4 year project and we now will be doing a moose hunt this next year. If someone wants a successful moose hunt check in Alaska fish and game website and register for a game ticket.

@@TridentConcepts think you mean "better" and I was just asking so we could see the full length of the true point blank and get a better picture of what is happening that's all. Why don't you just guesstimate it and add it to your video. So then you might state the average "point blank range" for a .308 at a 6" target is some 400 yds. That's all.

And what happens when target distance could be anything within capabilities of M4. Here’s an idea use the 25- 300 meter zero and you have a bullet drop compensation function to 600 meters from as issued sights plus out to 350 meters bullet will not be more than 10 inches high or 10 inches low from point of aim.

@@charlesludwig9173 The 300m zero is the worst zero you can obtain. It is pitiful at anything outside of 300m. The fact there are incredibly few ranges that actually go out to 300m is a major issue. Attempting to simulate a 300m at any other distance than 300m is not a 300m. That fact is undisputed. If you zero it 25m and pretend it works that's one thing. Seeing it in practical use is something completely different. Most shooters have difficulty shooting to at least a 2" group at 50 yards (4MOA) and you expect them to shoot better than that at 300m.

Any wind will influence the bullet's flight path. A 5.56mm at the ranges we are talking about is way less of an influencer over the shooter's & equipment's capability.

Yes, however that is a dynamic inquiry. There are too many undefined variables in your question to be able to give you a good answer. Cartridge load and temperature, ballistic coefficient, velocity, l/r barrel twist and ratio, atmospheric composition, amplitude and vector of wind, angle of departure, relationship of final firing position zenith to that of target etc, etc, etc.. In most cases though if you're engaging a sub-thousand yard target these effects will compound to a negligible sum. If you're hunting deer you're probably fine. If you're hunting squirrels past a thousand yard then you're going to want to investigate the physics of fluid dynamics in regards to ballistics. Specifically, the magnus effect. Good luck.

36 yard zero is the sweet spot for real world applications. Tried tested and proven. In reality there is no perfect zero, it should be adapted per application, if I’m door kicking with a red dot why do I need a 200 yard zero? I don’t. If your working in country on terrain that has visual engagement distances above 300 yards then I’m changing my optic for say an Acog and zeroing my rifle at 100-200 yards. Same terrain below 300 then it’s a holo sight or acog at 36. You can dick about with bullet weight math, barrel length and ballistic coefficients all day long, but in the heat of the moment you ain’t think about any of that crap. Setup for your application and intended use and move on.

There is no such thing, you either have one or the other. The fact you may see your projectile bisect at a certain distance dose not equate to an actual zero. People learn then in class or when actually firing from these ranges.
