A 6.5 Creedmoor pushing a 142-grain Nosler AccuBond Long Range 2700 fps and zeroed 3.45 inches high at 100 yards has a MPBR of 310 yards. spitting a 127-grain Barnes LRX 3500 fps and zeroed 2.84 inches high at 100 yards won’t drop 4 inches below POA until 381 yards. To increase MPBR, maximize velocity and ballistic coefficient. As long as you don’t throw too high at midrange, your bullet will stay in that 8-inch vital zone. The reason this works is because you’ve angled your barrel up enough that, like a center fielder throwing toward home plate, you’re throwing your bullet high to compensate for the long-range drop.
Then double-check it with the field-testing described above. Play with the numbers and zero ranges until you find the perfect MPBR. When bullets drop 4 inches below POA, you’ve reached your MPBR.Īs easier way to start this process is with an online ballistics calculator. When you’re hitting no higher than 4 inches at 150 to 180, shoot paper at 200 yards, 250 and 300 yards. If those land more than 4 inches high, re-zero 23/4 inches high at 100 yards and try again. That’s the peak trajectory distance (maximum ordinate) for most cartridges. Then fire two or three shots on paper at both 150 yards and 180 yards. Next, from a solid shooting rest, zero your rifle to strike 3 inches high at 100 yards. It leaves a couple of inches of “fudge factor” too. Eight inches is a safe bet that covers the heart and lungs of pronghorns, whitetails, sheep and anything larger that is standing broadside.
POINT BLANK GUN RANGE HOW TO
Here’s how to set up your rifle for its MPBR.įirst, determine the vital zone diameter of your game. Beyond 175 yards an adjustment of some kind will need to be made. This means that as long as the deer is inside of that range (or as long as the blue line is within the orange dashed bounds), just aiming directly at the animal will provide a kill shot. So long as your bullet doesn’t strike the top of the pipe, it remains in the kill zone until it hits the bottom of the pipe far downrange, your maximum point-blank range. As you can see, this particular rifle has a point-blank range of about 175 yards. If that doesn’t accommodate more than 90 percent of your shooting opportunities, you aren’t trying.Īn easy way to understand this is to imagine shooting right down the middle of a 400-yard-long pipe the diameter of your target's vital zone. Faster rounds extend MPBR as far as 400 yards. For all game the size of pronghorn and larger, most modern, popular “deer” cartridges can be set up for a 300-yard MPBR. A rifle’s MPBR is the total distance over which its bullet will travel without flying above or below the vital zone when you aim for its center.
