Does anyone know why the 36/300 yard zero is the only zero where the far number isn't actually the far zero? if you do a 36 yard zero with a 14.5/16 inch AR the far zero is at like 270 or 280 yards (or 250 meters) and you're like 3 inches low at 300 yards which is still fine for it being in point blank range but 300 yards is right about when the bullet starts dropping significantly as opposed to when the round crosses the sights for the second time. Where as with a 25/300 meter zero and a 50/200 meter yard zero (both of which aren't actually correct, 25 meters isn't the near zero for 300 meters and 50 yards isn't the near zero for 200 yards) the farther number is the point where the round crosses the front sight again. also, yeah I agree if you have an unmagnified optic/irons the zero literally does not matter at all. your ARs zero only matters if you need to match it up to your BDC because the variation between different zeros is pretty negligible within whatever range you're going to shoot in self defense
yeah
Depends on velocity. That 270 yard zero becomes a 300 yard zero with a mere ~200-300fps incease. Perhaps it’s 36/300 with a certain kind of ammo like m193, or it’s from a 20” barrel?Here’s a useful resource for MPBR. Near and far zero are both included in the outputs.https://shooterscalculator.com/point-blank-range.php
>>64668969there's a US army doc about different zeroes used by different units in the GWoT and if you take their numbers for m855 out of a 14.5 inch barrel and put it in with a 36 yard zero you get that like 270/280ish yard far zero with 300 yards being like 3.5 inches low and the peak of the arc being 3.5 inches high
>>64669009 I also use a 7” MPBR so +- 3.5”. I figure that’s about the size of a man’s head, so it’s the smallest you’d ever aim with a fighting rifle (I am a larper, I don’t actually shoot people). A roughly 300 yard MPBR sounds right for m855 from a 14.5. It gets like 2850fps or so. You’d be surprised how much drop there is between 270 and 300 yards. Far zero is always really close to MPBR. Fucking physics. Just an extra ~200fps will extend the zero to ~300 and MPBR to ~330yds
