[ARCHIVED THREAD] - max effective range?

Posted: 12/27/2008 3:26:07 PM EDT

Anyone know the difference of the max effective range between a 16 inch and a hbar 20 inch barrel?

I'm getting ready to build an AR with a short barrel, will be mostly used for target shooting/plinking, but may occasionally be used for coyotes. Just wondering how effect it would be for that or what the effective range would be.

Anyone.....Bueller?

depend on your skill and how far you can make hits with it

M16

* Maximum Range - 3,600 meters
* Max Effective Range for a Point Target - 550 meters
* Max Effective Range for an Area Target - 800 meters

M4

* Maximum Range - 3,600 meters
* Max Effective Range for a Point Target - 500 meters
* Max Effective Range for an Area Target - 600 meters

16"

Probably somewhere in between

For me when I could see that far, 350m w/20" M-16 std sights. Most folks 300. I would think somewhat less for the M-4 length rifle without glass.

But that's just me.

You should find a 1:7 twist barrel. If you use that twist rate then you can reach out there with a 16' barrel and throw a heavier round 62-77 grain.

I have read before that fmj bullets stop fragmenting reliably at ranges of 75 and 150 yds respectively for 16 and 20 inch barrels. (EDIT: note that just because it doesnt frag doesnt mean it doesnt hurt, my army bud says hes never had an issue with his m4 or m249 with his battle experience never exceeding 300 yds.) This information comes from an author who strongly poopoos the 223, but I do consider him knowledgeable. I know NOTHING about the hunting applications of 223 except that I wouldn't deer hunt with it. With 80 gr. bullets my friend who shoots NRA high power says he gets better consistency than his .308 friends, I believe him, hes a high master. I hope that with a grain of salt, this helps.

With optics, out to where the round goes subsonic if you can shoot. I have know of several cases of hitting men at 700-800 meter range with ACOG equipped rifles.

Rapid fire at 600 yards. Click for the service rifle training video.

This...though I must say I'll never have to worry about hitting anything that far out with my skills (or lack there of)

thanks for the replies guys.

I knew the max effective for the m16, I've put a pants load of rounds through those in the military. I just did not know if the shorter barrel made much of a difference.

My brother said that he was regularly hitting a 55 gallon drum at 800 meters while on a range in Iraq. Not every time, but more than 50% of the time. This was with an M16A4 w/RCO-A4 ACOG and M855.
