But this will degrade in to a P…..g match, so you sight in your guns your way and I will soldier on with my imperfect understanding of this universe. If only a portion of the target is visible (e.g., the head of an enemy soldier), the trajectory of the bullet may have to be taken into consideration when firing at a distance other than 300 yards/meters. And then it will be back within 2.5" back just over 200. The angle of your sights and or your view when aiming will be 0° in reference to the target because this is what your doing when aligning your iron sights with target; but now your barrel is angled up slightly. they have figured out a target you can zero on at 10 yards which will give you a 50/200 yard zero for your rifle at range. The round will not rise above the line of bore it will rise above the line of sight. The 50/225 IBZ0 is useful as the bullet has much less rise at the midpoint of the trajectory. thx for approving my user greetings wally.

In the recent carbine courses we have discussed various yard lines to zero your rifles along with the pros and cons of each yard line.  For those that have attended the courses now know that when it comes to your go-to 5.56 caliber carbine rifle that you would pick because it is best suited for all possible scenarios, the 36 yard zero seems to be the perfect fit.  Of course, this is a matter of opinion, but when it comes to making accurate shots from point blank distance all the way out to 300 yards you really can’t argue that the 36 yard zero makes thinking about your hold overs and unders a breeze, which is especially the case when you’re under extreme stress.  There’s a problem though, the majority of shooters do not have regular access to a gun range where they can get much distance outside of 25 yards.  So how do we get the 36 yard zero with only 25 yards to work with? With both the 55 grn M193 and the 62 grn SS109? I did maximize to 100% but squares seem small. Therefore, if we are hunting white tailed deer, we can tolerate a maximum rise and drop of 5″. a bullet will rise with enough force pushing it foward thats why jet boats or cars going fast enough will fly if going fast enough. When your sights are aligned perfectly horizontally, the barrel of your firearm is canted very slightly up, to impart an initial upward velocity. In other words, it SHOULD be on at 50 yards. First, PK posted on April 30, 2010 that a “bullet NEVER rises once it leaves the muzzle of any firearm.” I can’t tell if he is joking or if he is that damn stupid. Well to componsate for the fall of the bullet as it looses speed and atmospheric pressure takes more and moreeffect on pushing the bullet down. i am so satisfacted.my english is poor, sorry :). The bullet never rises above the straight line projected by the bore site. You will still need to confirm and refine your BZO at those appropriate distances. The Gunnery Sergeant in Full Metal Jacket was a real Marine. All zeroed in at 36 yards! If you have access to a 200 yard range you can try confirming there too (I don’t have access to that long of a range at the moment). 36 yards zero is about 1.25" high at 100 yards 25 will get you to 325ish and 2+ " high at 100. I was in Basic in October 1979, being forced to do what seemed liked countless pushups, flutterkicks, and several other excercises I can’t even remember. Here’s another cool little experiment….

USMC 83-87 And then it will be back within 2.5" back just over 200. At 25 yards, groups are .7” inches high above center of target, just under 3/4", w/ rear sight set on “2”- so a 200 meter battle zero is a little better. Most rifles are set up to launch me slightly upward so you can use to me to hit things that are further away. I am a simple guy, and I’ll only fly where you tell me to fly, I do not have a built in computer or magical powers to rise on my own, but if you point your barrel up a little in relation to your sights, you will get a lot more use out of me. Talk me out of 36 yard zero I've read through most pages of the zero threads. The difference between a 50/200 yard zero and 100 yard zero at 10 yards is only about 1/10th of an inch (1.92″ below point of aim for the 50 yard zero versus 2.06″ below point of aim for the 100 yard zero). As you know, traditionally the sighting device is 1″ – 2.5″ above the bore. No one who is still trying to understand this shooting 101 concept needs to be confused by spin-effects that won’t affect their early learning curve. If you point a gun in the air and pull the trigger, does the bullet fall straight to the ground? display: none !important; If this were to be setup precisely with no distractions to the round while carrying the 300 yard length, you would have a hole at the 36 target and 300 target to be fairly fairly close to the exact same elevation while the 150 yard target would be much higher. If you’re going to zero at 10 yards, then confirm your zero if possible. Can’t seem to get the scaling right. “What does change is the trajectory of the individual bullet/cartridge.”. 15 yard zero 25 yards is +0.2 50 yards is -0.6 75 yards is -3.4 100 yards is -8.3 25 yard zero 25 yards is +0.0 50 yards is -1.0 75 yards is -4.0 100 yards is -9.1 Another reason to zero at 10 yards in the accuracy of pistols in general. Although I did a boatload of “remedial” exercises that afternoon, I never changed my argument. Learn them or they will cause regret. ref: my request for help saving target as desktop file, When zeroing at 36yd how then do I zero a DBAL A2 using a constant offset target method. I think the 10/50 yard zero works because 50 yards is basically point shooting distance for a man sized target. It then descends until it is again exactly on the line of sight at 300 yards. The battlesight zero used by Marines when shooting the iron sight M16A2 is the 36/300 zero, meaning that the bullet will be on the sight line at 36 yards and again at 300 yards. A 50 yard zero allows the shooter to use a simple center-mass hold to ranges of point blank to 200-250 yards, depending on rifle and ammunition combination. The sites will angle the rifle upwards because of gravity pulling the round down. The bullet is fired from the barrel and rises up to be exactly on the line of sight at 36 yards. This gives the Marine a good aiming point for a man sized target at any distance between 0 and just over 300 yards. the bullet trajectory is not affect by this as the projectile is of uniform shape (in theory) so that the air is traveling a close enough speed on all sides to not create lift. Luckily, if your rifle is properly sighted in for its maximum point blank range (MPBR) you don’t need to know the exact distance. The over simplified example in the Marine manual is horribly worded and the illustration is even worse leading to this widespread misconception. The 100 yard zero with a .223/5.56mm AR-15 carbine is a unique trajectory in that the bullet just “kisses” the line of sight at 100 yards and rides along it for approximately 10 yards before dropping back down below the line of sight.

Great thing about this zero is that all the way out to 300 yards, you only have a 5.5" spread. Using this value, it is simple to calculate that the MPBR for a 180 grain Remington Core-Lokt .308 roundnose soft point cartridge in my trusty Remington 700 is 293 yards, with our second zero at 252 yards. The problem with zeroing your rifle for 293 yards in this case is that not many people have access to a 300 yard range. It is evident he has never been in any of the Combat Arms MOSs (if he was even in the military). As the forces of gravity and friction slow the bullet down the anglular forces lessen. 7 Discounting a very small amount of spin induced lift, gravitational anomalies, and possibly weather related input; a bullet will not rise of it’s own accord. We want you, our readers, to be able to make informed decisions. −  Lets assume for this example that our range only has a 50 yard rifle range. End of story.
