That's quite astounding with a lightweight rifle with a pencil barrel.
You must mean a KKJ-T like the one immediately below, and not the usual model below it. In any case, 7/8" groups at 100 yards with CCI SV is incredible even with the heavier barrelled one.
Yes, that is very much like mine. Here's a couple pics of the group. What really got me is that I shot it with CCI SV straight out of the box (normally I weigh it).https://imgur.com/fxed11Ahttps://imgur.com/W2wc0eL

Nice ruler!
Oh, excellent group also.

Pretty windy out, but I got some pretty respectable groups for the circumstances. The rifle was properly settled in bags, front and back. The four good groups were shot with either Eley Match or Tenex. Clearly I still have some operator issues to work out, but the gun seems to perform quite well, and the wind didn't help any.

Try different ammo, Im into CPRS/NRL 22 stuff and I've switched over to Eley Force since it seems to be the most consistent ammo at distance I've found so far out of my Mark II. Just got an IBI on my 10/22 so we will see if that maintains. I cannot wait!
Edit: I'm hovering around 1" at 100 yards if condition are calm, most of that is wind, seriously a small gust of wind and its sayonara 10 shot group at 200 yards I open up to around 2.5" - 3".

That's quite incredible for a factory barrel on a 10/22. Do you have any pictures of that remarkable shooting?
One would expect considerable improvement with the IBI barrel.
I should've been clearer, thats my Savage MKII, my 10/22 just got a near barrel and I'm hoping it will be my new go-to rifle if it shoots as well as my MK II.
That's still literally incredible for a factory barreled Savage MkII. Any pictures?
Yup sure do, let me get it uploaded. It's been a long time. The two groups on the left are Lapua SK at 100 (10 shots) the good group on the right is Eley Force 10 rounds as well. Factory barrel, Oryx MK II chassis, shot off a CKYE Pod and warhorse rear bag. August 30 2019.

That 10 shot group at 100 yards on the right is literally unbelievable shooting.
Apologies for my uncouth friend, buji88. He is calling you a liar. Funny how I've never seen him post any targets shot beyond 57 yards, yet he is right quick to call out those who have. That's a great 10 shot group there, sub 3/4" by the looks of it. I believe it, I've had a Savage that was a great shooter and with another rifle I've done sub-moa 10 shot groups at 200 yards a few times. It is doable accuracy, for those that spend less time on ballistic calculators and more time shooting long range
Fair enough, I didn't believe it either when I first started glassing it through my scope. I initially thought maybe three had landed, and the rest were off the paper. Believe it or not, the SK on left shot much better at 50 than the force and this was me being really confused while doing 100-yard testing. All I can do is present the information if you choose to believe it or not is up to you!

Thank you! Hey, its the internet and I'm kind of boasting, all I can is present what happened and my fellow CGNers can make up their own minds! Yes, this Mark II has been one of the most accurate I've ever owned, at 200 yards though it's really tough to keep a decent grouping. I've been super happy with the combo, hope my 10/22 build can shoot as well as this rifle has!

Thank you so much!
It's necessary to put this in some perspective. It's said that at 100 yards the Eley Force was so good that it shot a ten-shot group somewhere between .750" and .875" (or 3/4" - 7/8") -- based on the grid on the target being 1" apart. It's hard to imagine .22LR ammo being less accurate at a shorter distance, therefore the Eley must have shot awfully tight groups at 50 yards. Nevertheless, at 50 yards, the SK (Standard Plus? Rifle Match?) shot even better than the Eley Force. The SK must have shot almost uniquely remarkable groups at 50 yards to do better than the ammo that shot the .875" ten-shot group at 100.
A 50 yard group would be more than twice as small as a 100 yard group. In other words, to use an example, if a group was .500" at 50 yards, it can be expected to be more than doubled in size at 100 yards. A loose rule of thumb for .22LR shooting holds that as distance doubles group size triples. In reverse, as distance is halved, group size would be a third of what it is at the greater distance. As a result, a .500" group shot at 50 yards can be expected to be closer to 1.5" rather than 1" at 100. The corollary is that a 1" group at 100 yards will be closer to .33" at 50. To be sure, this is not necessarily a physical law that applies accurately each and every time, but it is a general rule of thumb that is a very reasonable approximation.
The Eley Force ten-shot-group at 100 yards is ostensibly very close to .875" would have to be at least .4375" at 50 yards -- and by all reason even less. To apply the rule of thumb, that Eley Force ten-shot-group at 50 yards would be .292" (or 7.42mm). But even simply halving the group size allegedly achieved at 100 yards, a ten-shot-group at 50 yards that measured .4375" (or 11.1mm) is still very good indeed.
In fact it is good enough to be considered quite a good factory test target achieved with the barreled action in a specially-made testing vise. To give some perspective, Anschutz tests its rifles in an indoor range with the barreled action in a vise. The minimum standard for accuracy is a ten-shot group at 50 yards that measures no more than 18mm (.709"). Anschutz 54 action single shot match rifles do much better than meet that standard. Keep in mind, of course, that these tests are done indoors with no wind whatsoever and with the barreled action in a vise.
To sum up, the Eley Force is alleged to have produced a ten-shot-group at 100 yards that is about .875" -- a size which would still be quite remarkable for a five-shot-group at that distance. At 50 yards this ammo would shoot a ten-shot-group no more than .4375" but very likely even better, perhaps as small as .292". Furthermore, the SK ammo shot so well at 50 yards that it was even better than the Eley Force, which itself is quite extraordinary considering how well the Eley had to shoot. Unfortunately the SK did not hold much accuracy at 100, but that in itself is not surprising as not all ammo remains consistent as distance increases.
If the results claimed above are genuine, then it suggests one or more of several possibilities. First, it's a one-off, hardly ever to be reproduced with that rifle again, sort of like picking the right lotto numbers for next Saturday night. Second, the rifle is very unusual in that it is a one-of-a-kind factory barreled Savage Mark II capable of extraordinary accuracy. Third, there is a force at work here that engendered a confluence of incredible fortune in shooter, rifle, and ammo. Fourth, there is a mistake made somewhere. Unfortunately, the alternative is that it didn't happen as described.
