Might be the wrong forum, BUT, was wondering if you guys can give me an idea of accurate range for my rifle...
Specs are:  Kotonics 18"  1:11 barrel, Ops Inc brake and MUR1A upper receiver...  Cuurently has an NcStar 6-24X50 rangefinder scope on it...
I've never fired it, but was wondering if the optics are adeqate, or do I need to buy something better, and how far ot it will be accurate...
Thanks, Dan

The range of most 6.8 rigs will be around 400yds, for game. At that distance, the bullet is at the end of its velocity threshold of expanding reliabliy. While you might hit a deer at that range, the bullet may not perform well enough to finish the job.

Target shooting can be as far as you can call your dope, there have been several taken out to 1000 yards. Not a good choice for such shooting but it can be done. I can get half to 3/4" moa groups out to 300yds with reloads, haven't had the time to go further out.

I'd upgrade that scope to a $300-$400 Bushnell or Nikon, if you are wanting to stretch out there. Burris has some models in that price range also that are nice.

I shoot my 16" 6.8 at an 8" steel plate at 350 yards all day long.
That's the limit of my local range, I'm sure it would be accurate well past that from a purely target shooting stand point.
I'm using a 3-9x44 scope.

400 yards is about its limit for taking small game like Elk

accurate range there are guys on the 6.8 forums shooting iron plates at 600 plus yards



 

I was shooting my Grendel next to a guy shooting a 6.8 with a 32X optic, and he was matching me out to 400 yards.  At 600 yards I was dusting him, as his bullet was starting to get tossed around.





Past 600 yards my Grendel would have lost steam, and anyone with a .300 Win Mag would have still been slicing through the wind.

 

It's all dependent on the wind. The 140 Berger should be good to 7-800 in ~10kts of wind. I have shot factory Hornady 110 BTHP to 1000yds (16" Noveske barrel) a couple times with variable winds and it did fine.

Elk isn't small game. Hogs are small game. I'd seriously think long and hard before going after elk with a 6.8!

Constructor got one a few years ago with one and others on the 6.8 forum have done the same

Maybe not the best choice but it has been done, several times by the 6.8 and 6.5/.264.

i would have no problem with it
it just a big deer

Honestly the way you worded your question accuracy and range accuracy is generally the same thing.  If you're shooting 1/2 MOA at 100 yards you're gonna get 1/2 MOA at 500 yards.  With no wind that is.   If you're question is more about effective range that's easier to answer which some seemed to have answered.

The 6.5 Grendel has traditionally had the range advantage due to slightly heavier bullet/powder charge combination.   However the 6.8 has slowly extended it's legs.   With the release of the Berger 140 gr VLD bullet for the 6.8 the Grendel advantage has been pretty much lost.

Knowing the ballistics of the your load is what is required to hit targets at range no matter what round you're shooting.  Hitting steel plates at 800 yards is different though than dropping game animals.

+1 on the 400 yard limit for terminal performance on deer-sized game.  If hunting elk in heavy timber where the range will be limited to 300 yards or less, I think you would be okay, but if you miss the kill zone,

they in all probability will get away.



I shot a deer the other day at 185 yards horizontal (steep incline) with a 120 SST and 27.2 grains of A2200.  Hit it in the ribs about halfway up and it went clear through and came out low on the other side due to the

inlcline.  It took 5 steps and laid down behind a sagebrush and that was it.  I tried to find the bullet in the dirt to measure expansion but could not.  The exit hole was less than an inch, no meat damage.



I love this cartridge, no recoil, blast isn't bad, no tensing up, like shooting a .22.  The deer had no idea where I was after the shot, I could have shot 3 more.

There are lot of folks who are taking elk with a 6.8. I would have no reservation if I were in a state that had them and my range was decent.

My chrony said about 2550 from an 18" barrel 1-11 spec II. However, according to actual shooting dope out to 700, it figures out more like 2535. I use a 200 yard zero, 10" or so drop at 300. It's about identical



to the Hornady Superformance 120 SST.



ETA:  The bullet missed the ribs on boths sides.
