Honestly here, HONESTLY! What is the longest shooting sequence anyone here on the forum has done with a Grendel? Say 5 shot group, all hits on the target, accurately, and doping in for it...
I'd like to see how far everyone is pushing it accurately... (THIS DOES NOT MEAN 20 SHOTS AND 5 HITS, NOR 1 HIT POT SHOTS!!!!)
Mine is 850 yards still to date, havent had a chance to try further yet...

I had 4 out of 5 at 1200yds, which really surprised me. There was no wind, but I had really figured my little 16" Grendel was only a 700yd carbine at best. This was at 4400ft ASL, 80 F. 14.4 Mils, 123gr Factory A-MAX.
I think the tight 7.5 twist of the 16" barrel helps with stab factor. Here's the area I was in from another trip, but this target is at 400yds, as seen through my 16":

Somebody shoots beyond a thousand yards from memory, maybe up to 1200 yards but at altitude! 4000 or 5000'.
I shot on Thursday out to 1000 yds, wind was all over the place, I was able to consistently hit a full size steel silhouette. Was also hitting smaller targets but not consistently. Sea level, 60 deg F, 2600 FPS, 123 AMAX.
Not sure if this helps but 800 yds is probably my maximum when it comes to hitting a smaller target consistently.

There was a forum member who posted 1300yd groups on steel up in Idaho, and a lot of people had a hard time believing it.
At the end of the day, we're pushing 100-123gr target bullets with 27-32gr of powder charge, so while the expectation shouldn't be unrealistic, don't be surprised at what it can do with the right set-up, especially up here in thin air.
Longest hunting shot we know of is 752yds on antelope with a 22" Lilja barreled Precision Firearms AR15, with the 123gr A-MAX. He registered the shot at 727yds before the herd came through, so he had solid data on exactly what was going on with his trajectory.

Here is some great video from a forum member shooting 800-1100yds.

20 shots at 1000 yards in F Class Open match. Score 184 3 Xs, a few 10s. Completely blew a wind shift and threw some out on the edge for 6s. Altitude about 650 feet.

Interesting... most of yall sound like your way higher up than i am. That 850 yards was at 834ft altitude. That thinner air makes a huge difference. I know there had to be a few getting it to around 1200... i havent quite pin pointed where my load goes subsonic and starts tumbling yet...

As long as we have no wind (fat chance!) or relatively steady wind, 1200 yds is also our maximum reliable range, requiring 13.1 mils of elevation, but easy hits on full-size IPSC steel, though any further gets unreliable (presumably transsonic instability)—20" Krieger 1-8" twist, 123gn Lapua Scenars, 2644fps MV, 105°F., 1909' density altitude

Reading some of litz's stuff and doing a little experimenting in other calibers, stable bullets can stay stable far past transonic.

Back in May, I took a long range shooting course from Bangsteel.com in Wytheville, Va. Shooting my Precision Arms Grendel out to 1100 yards. Bullet drop at that range is about 36 feet. Elevation about 2600 feet. Amazing to hit that far out, as long as you read the wind correctly

1230 yards but tough with wind ..once we're on its grouping. . 123gr scenars 2530fps out of 19" lilja..sea level ....subsonic by then but fun to shoot. Really a 700-800 yard gun

I ran across some 123 lapua scenars the other day and thought to myself how those may shoot well too... but, i have a hard time messing with my load since it already shoots...

Oh i have all that info already! Got it all organized on spreadsheets too. What kills me is my altitude. Its humid here a lot, but humidty doesnt effect it near as much as altitude does. Id have to look at my charts again but my range here at 834ft is only +-1000ish if i remember right with all my data. Which really is no big deal anyways, i run a custom built Tac 260 chamber rifle for a little bit longer playing, then my custom 338 lapua is at the shop being built as we speak, should get that back in the next week or 2!

When I mount a scope, I level the upper, and level the scope to the upper, with the bottom reticle line going through the bore on low power. I then level the scope level to the gun. I have also used a plum line in the past to level the reticle through the vertical line.
Any rifle I plan to shoot distance with gets a level now. You can see huge windage misses without a scope level.
