Balance that with your portability needs. Not sure if anyone else has tried this or not, but it’s definitely worked well for me. It is good advice and I have a few rifles zero’ed for 50 myself, but it’s not the “best zero”. With our example of a 6 inch diameter target and a MPBR of 300 yards, I still want to be able to hit the target in a slight wind. “UP & towards the MAG!”, you can get a good feel for your holds even with something as unscientific as that. The theory is that, with common big game cartridges, a “zero” at 25 yards will correlate to a second “zero” at 100 yards. With a 50 yard zero, your bullet will only be about 1.57 inches above the line of sight at 100 yards and height maxes out just over 2 inches above around 150 yards… A solid option for shooting a short-barreled  223/5.56 to 200 yards. We want to put rounds on target, with the highest probability to intersect the target, without having to try and estimate range. Above Sig Romeo 5 with Juliet 3x magnifier. 175…………………………+ 0.3 I found that between a 15 to 25m zero was good for this but put me way off at 100 for qualification. MPBR is a zero scheme that is unique to your rifle and loading. I really like this method as it increases the probability of intersecting the target at x range inside my MPBR zone. Keep up the good work. 25………………………….- 1.2 Point Blank Range gets rid of the math for most all shooting scenarios. As everyone said its very unlikely for anyone of us to shoot past 25 yards in a self defense situation, but its all academic since I will most likely have my pistol if a self defense situation arises. What I mean by different rifle zeros, Specifically in 223 or 5.56 caliber rifles, is the different ranges you can zero your rifle at and how they affect the trajectory. The old school way you would zero your rifle is at 100 yards… that way everything is just a holding above the target past 100 yards (known as holdover). Up to me to do the shooting and fiddle-out the results. Works with 2MOA and 4MOA dots, and can also be applied with magnified optics. The 50 yard zero provides for effective center-mass hits on target at the ranges where a carbine is most commonly used. If each rifle setup is unique, then can we do better than a “vanilla” zero for each rig? i wanted to try some 50 yard shots at the range with my g21 last week. The 6 o’clock position reticle wire at the top gives me 400 yd or so BDC spot to shoot from. Groupings are the defining measure of whether an MPBR zero will be effective as inaccurate ammo could possibly land too far away from our target radius to remain useful. This zero is actually a 264 yard zero which gives us a 3 inch rise and a 3 inch fall at 300 which marks the end of our MPBR. It’s important to get away from the 100-200-300 yard paradigm and examine a zero which allows a more fluid approach to hitting a target at unknown ranges… because remember this, if nothing else; every field target will present at an unknown range. Both of these characteristics are just what we want when setting up our rifle or carbine. I can also hold the same sight picture at 150 yards as I did at 100 yards even though the round may hit at 2.7″ low of zero. . Oh one thing guys, where is this being shared on facebook? Anything inside of my MPBR I want to aim at and hit without worrying about holdover, hold under, or BDC stadia. Success in any of this will depend on training. where you got info that M193 is considered 1.5 MOA accurate I have no idea. Behind the curtain is the true monstrosity that is unchained and unhinged man. That means that with a 100-yard zero, the bullet will rise ½ inch above line of sight at 50 yards; 1.8 inches above at 100 yards with a 200-yard zero, and 4.7 inches above at 150 yards with a 300-yard zero. Point of aim/point of impact out to 200-225 yards, depending on ammunition and barrel length. But the 36 yard zero is flatter out to 300. Quite a few school hallways Quite a few parking lots. There is no remembering hold unders, you just aim a little high inside 100 and keep going higher past 100. Use a ballistic calculator app such as Strelok! WTH you want to chase all the old guys away…. Pros: Your largest hold under is about 1.5” at 125 yards which in my book is point and shoot. I rarely post .. but stop every so often. Each rifle and loading will need to be entered in Strelok (or another ballistic calculator) to determine the best zero for your desired target diameter. I use simple terms that I think would help people understand the concepts, even if they aren’t the ” correct” terms. Wouldn’t ya know ? This is a deer hunting rifle and from time to time range rifle (473 yard max as my hunting property is also my range). With a 50/200 MPBR zero, there is only a 3 to 4-inch difference in point of aim and point of impact from 50 yards to 250 yards. little details like this help noobies like me when we actually go to the range and start to try and put this to practice. Again, with easy-to-understand math. Under stress, our accuracy already will suffer. So what should be our goal when we zero? And the bullet never lies. 50…………………………..- 0.2 My caveat: if I had a BDC reticle like Lothaen instead of a scale reticle, I’d probably zero so that my trajectory matched the reticle as much as possible. Range Gear: Lynx Defense Pistol Range Bag, Magpul Introduces New MBUS Pro LR with BDC adjustment, A Parable for the Poors: Palmetto State Armory v.s. The 50-yard zero has flatter hold unders than the 36 yard zero out to 200. The value of PBZ as you say is to reduce the amount of thinking by the shooter in a stress situation, by maximizing the distance within which one doesn’t have to apply elevation correction. You enter that 100-yard zero into Ballistic, as well as sight height and other Bullet Profile data, andBallistic instantly provides the MOA or MIL RAD holdover needed at every shooting distance. i do not notice any displacement on this issue as far as putting holes on the target. TNR’s First Shirt for Pre-Order! Just a quick anecdote on match ammo performance: multiple tests have shown that open tipped match bullets such as the 77 gr and 75 gr jacketed match ammo perform well in a defensive role and show substantial fragmentation: 75gr test and 77gr test. The key is, get the longest barrel accplicable to your needs. The 50 yard zero is still going to give you "point blank range" out to 200 or a bit longer. Has any one had experience with the 36 yard zero? What you do is your business, but we do enjoy reading about it. No worries! If each rifle setup is unique, then can we do better than a “vanilla” zero for each rig? It is my understanding that this zero allows for the least amount of holdover when using the M855/62 grain Green Tip. Myself, with a 14.7″ barreled, 5.56mm I’m using a 100 yard zero with a GRSC 1-6x scope. With a 50 yard zero in a 20-inch rifle, shooting XM193, you can expect a bullet apex (aka maximum ordinate) of flight to be close to 2 inches (by my calculations) and then it falls back to cross your line of sight again at 225 yards. I Am Not a 1 MOA Shooter… and I Don’t Have To Be. I always thought / recall it was a 2.5-3 moa round. In this article, I will be posting some data to share how much the bullet has risen and fallen at different distances with different zeros. Six inches of total vertical resolution seems like a logical choice for an MPBR setup and extends us past our 50 yard / 200 yard zero a bit and is still a fine resolution for engaging defensive targets. My rifle is being set up for the worst case scenario. I based the data on what I would consider best practice. I think, again in theory, that using the MPBR method would likely put you in the terminal zone as often as other zero’s particularly if our target is at a unknown distance. So I went to a rather busy range last Wed. and decided to set my 300 yard target at 400…read more →, Today was my first day at the range with my simulated 300 meter target. Cons: Not ideal for a red dot zero. I was inspired to make…read more →. THANKS FOR VISITING! My advice is to get a ballistic calculator and put in your specific data because there are all sorts of things that will affect the results. When this is added to your drop, the zero hold difference becomes even shorter. I’ve seen that work out to useful holds with 200y zeros as well as 100s, depending on the scope and load – whatever gets you closest to big round numbers. Boom. I think these loading’s can cover all shooting I can ever realistically do. To you and me in a court of law I could bring myself to believe it’s possible. precision rig) I zero at 100 meters and dope from there. It will cross your line of sight twice; once at where you zeroed it, and once again when the bullet starts to drop. Torso? Strelok has a wonderful tool built in that lets you calculate the maximum point blank range right in the app and is a powerful tool. Wind can cause us a horizontal shift away from our intended goal of hitting the target. The other problem is that a 10 yard zero basically makes the rifle unusable for any distance beyond 10 yards. With rifles like the AR15 and the typical ranges of the intermediate cartridge (normally within 300 yards), you can “manipulate” the bullet trajectory. I am not a fan of increasing the size of the target area in order to increase the distance one can use a point blank zero concept. I am having no issues consistently hitting the combat effective zone at 300 yards. Match bullets and/or the heavier bullets on the spectrum are often not the best defensive choices, as shown from data on shooting incidents or scientific testing in media. furthermore. This 6 inch resolution is easily inside the vital zone of a center of mass hold. Thinking that your going to be in some, one shot one kill, ranging your targets and adjusting your come ups or even looking at your dope card is crazy in anything I could think of ever doing in a self defense situation. If you are interested in a more standard AR15 zero method, check out the article linked and visit Soldier Systems. I knocked the NF off the table ! The Final Zero – The Gun Vice Method. The 36 Yard Zero Target. In the 20 inch gun, the Mk262 gives us an MPBR for our six-inch diameter target of 284 yards which sacrifices 16 yards from XM193… but the gains in accuracy and wind deflection make it the logical choice for a shooter who wants statistically significant gains on hit probability. Other ballistic software I've tried (I show one chart as an answer to your previous question) shows that with a 50 yard zero, you will be right ON at 100 yards. ... 50 PM Re: Whats a good site in distance (zero) for a .22-.250?? Sorry, your blog cannot share posts by email. I even had good luck on moving targets at 300-400 yards with that zero as we used to hold up targets on sticks and walk them through the rifle pit while those on the firing line got to shoot at the movers. If you had a bit of error and let the shot loose another inch high would 3 inches of rise miss a head-shot?
