You need to get out more!!
They tend to hover around 2 MOA with surplus fodder and gun shop special/sale stuff, but with quality ammo that the rifle really likes (match or high-end hunting loads) or handloads tuned specifically for the rifle, you can get them well into the 1MOA range if you do your part (I've only put them on paper out to 200yds). The furthest I have ever shot one was 500yds with a garbage 2.5-10x optic, but hits on 10" plates were normal and consistent for both me and the rifle's owner. That rifle really loved the 155gr AMAX load that he had worked up for it. I have never actually put one on paper at longer ranges to determine what precise levels of accuracy it was capable of, but it was less than 2MOA in my best guesstimate based on what I did and otherwise witnessed at 500yds on plates of that size.
As with any of the delayed roller lock action/designs, they are BRUTAL on brass thanks to the action/design of the rifle itself as well as throwing brass a blue country mile away (usually they toss brass at roughly 2 o'clock or so and every bit of 15yds away give or take so the brass gets the @#$% beat out of it by the chamber, upon ejection/extraction and whatever it lands on, rolls around on or gets stepped on once its on the ground).
They are truly excellent rifles in my experience with several SL7 and 770 rifles over the years, but thanks to the supply on them drying up, few of them being for sale at any given time, and the demand for them when they do come up, the prices tend to be fairly high for what they are. Some of the triggers were truly excellent while others had some heavier weights of pull and a little slop to them. Bill Springfield can do trigger work on them if you happen to need a trigger job to help with the accuracy front, but just be cautious about doing anything on them yourself if, like many, you pride yourself on being a good weekend mechanic/basement gunsmith. A new trigger pack will cost you...BIG TIME...if something goes awry, assuming you can find one for sale at all.
I meet a older guy at the gun show last week he said he had to rifles for sale and hasn't shot them since the early 80's. I went to check them out ones a steyr SSG with set trigger old zeiss scope mint condition with papers when he bought it in 79 and a H&K 770 mint early model with no muzzle looks new with an old redfield 3x-9x widefield scope and looking threw it he had it set up for 600 yards. He said he bought them to shoot at the range every now and then but ended up not shooting much he bought both rifles because someone recommended them to him back then.. anyways he wants $3500 for them I told him early today I would take them he found some more stuff to go with them extra scope mount for the H&K and 4 clips and 880 rounds of old 1968 lake city 308 ammo.
I'd say that's a @#$%ING STEAL. Hell, even a well used 770 in fair condition can fetch nearly $2k (I know of one now that is in 80% or a bit better for $1800) and I couldn't venture a guess on the SSG as I haven't kept up much on them over the years. If the HK is really in minty shape, especially with mags going for a metric ton of money each, particularly 10rnd mags if they happen to be, you are likely hosing the poor fella pretty good for both rifles, mags, ammo, etc.
I have one; actually the wife's deer & bear rifle since the mid 1980's. Extremely reliable with relatively light recoil and a few quirky design aspects, like the side mounted safety and a flash suppressor/threaded muzzle. I was fortunate to buy the H&K scope mount with both 1" and 30MM rings. The three shot magazine is a pain, but 4 rounds if you load one up the spout. Optional 10 round magazines were available as well.
Scope is mounted fairly high, but for field and offhand shooting it's a more natural feel. The slim forend is comfortable and points well and quickly. All and all a fun if unique rifle. The rifle shoots extremely well with a tuned handload.
I have one as well with the flash arrestor/muzzle brake thingy and a few assorted 10 rd mags I bought some 30 years ago. It kills brass and in a hurry.
770 delivered 30 days ago and seller paid to have inspected because it keep jamming when you rack it 2". The gunsmith who took it apart gave up a week later and handed bolt piece back. The seller said to ship it back and his gunsmith would repair! Well rather than ship 1300 miles over poor highways, I decided to email over 35 gunsmiths to see if they were certified by HK. After 3 weeks John Andrewski in New Hampshire agreed to inspect the 770 to see what was causing the jams.
Rock Island did a video on SL7 and showed the two steps how the bolt unlocks, then racks.After disassembly four time and some research to clear the jam, by remove 5mm bolt, cover, buffer and spring and used padded flat head screw driver and twist between carrier and barrel extension carefully to move the PIA locking lever lug to the ridge of the bolt head.
In a telephone call from Marc Whitacre, a writer for America Gunsmith Association he sent a link for a US ARMY paper on G3 7.62vs5.56 which explains the amount of force it takes to pull the cocking lever on G3's. But 770 bolt assembly is in direct line with recoil spring. So the amount of force may be more!
Three major springs must be pressed. The 44# locking lever to move the head back; then the hammer and spring say 50#; and finally the recoil spring that is fighting you when it compresses.
These guns need lots of grease but HK 770 Owners manual doesnt give you any help. HK customer service says they dont support guns over 20 years! Trial and error.

I owned one a number of years back. Used it to kill my black bear in Montana in '91. 250 yards - shot great. It liked Federal with 180 gr Nosler Partitions. Other than what's already been said about this rifle, I didn't like that you needed an Allen wrench to disassemble the darn thing to fully clean it. Had the claw mount scope mount and 4-5 10 round mags for it as well.
Sold it off when the import ban was enacted. Didn't want to be caught in a jam if something broke and I couldn't get parts. Replaced it with a Remmy 700PSS. I'm happy with it as well.
I can speak no ill about it other than the quirky stuff already stated.
