300 yd shooting with an AR 15? - Page 2

MTT TL · July 12, 2018, 05:19 PM

300 yards, supported and unsupported, with iron sites, military ammo, on man sized silhouettes pop-up targets for 24 years.

With a 1/7 twist and 62gr ammo, factory ammo and 1-10X scope a 12" gong is easy.

Shot out to 600m, open sights in the Army as well. I could hit the reactive target 8/9 out of 10 times with 19 year old eyes. No idea what my groups were, but I could get the projectile there.

Next I am going to try 24.5 of Varget with the same bullet, primer and brass.

Is it possible that a 77 gr SMK could do any better ?

Is a Caldwell front bench rest better than a tripod ?

The 77's might not be ideal with your slower 1-9 twist barrel. A front rest will always be a better choice than a bipod. If you must shoot bench precision with a bipod, screw or clamp a small board to the table in front of the bipod feet and use your shoulder to slightly push forward and "load" the bipod. This removes most all potential unwanted bipod movement.

It will put holes in paper with iron sighs at 300 meters all day long.

Don't recall firing at anyone beyond a 100 meters or so

But it is not a great man stopper at longer distances. That is why I carried an M21 in the GMV on my second and subsequent tours.

Roger that. It's probably my favorite (M21) "rifle".

Agree, I shoot the 77' In my JP Wylde and go 300 and beyond no problem.

I doubt you'd stabilize a 77 gr bullet with a 1 in 9 twist. A 1 in 9 works fine with 69 gr bullets.
I found Varget worked best for me with a 1 in 9 twist 16 in Hbar.

With a 1 in 8 twist and 75 to 77 gr bullets,RE-15 was the best I found.

The heaviest expanding varmint bullet I found was the 60 gr Varmint Ballistic Tip. Benchmark worked very well with this bullet in a 1 in 9
