most offhand is for score rather than group.  From what I've seen 200 on a ten shot target, or 2000 for a 100 shot, I'd judge pretty darn good.  If you kept all shots inside or touching the 20 ring which measures 9" on the 200 yard target (or a roughly theoretical 4.5 MOA "group") that'd give you a score of 200/2000, and probably better since a fair portion of those shots would probably be better scores than 20's---and you'd win a lot of matches. 
  Just a quick scan through the newest ASSRA Journal  record section and the current match scores for offhand results is interesting. It seems most of the 200 yard offhand record scores are in the 220/2200 range.   Most of the current matches are won with scores from 205 up to 215 or a little more.   I'd just guess from what is posted that the bell-curve bulk of the offhand shooters are shooting in the 175-195 (for 10 shots) range.    You can translate that to MOA,

I'm still well down the learning curve on offhand,  my personal goal at this point is to use the small red as my among point, trying to keep all the shots in the rings.
  If I could eliminate all the "10s", (the shots that have fallen outside the rings but still on the paper) my scores would be significantly better.   And I believe that is more of a shooting skill problem than an issue of load or load technique at this point

It seems most of the 200 yard offhand record scores are in the 220 range.

The Alberta Schuetzen Guild record is Colleen Molendyk's 462/500. Some of the top offhand competitors can shoot 230 to 235 targets offhand.

My highest 10 shot perfect target at 200 yards was .799 inch bench group. I understand others have shot tighter groups.

Back in 1991 at Golden there were at least 4 (one of my own) individual targets over 230. I would say that the top 5% typically are working at keeping all hits inside the orange (22 or better. I recall Jim Feren  shooting at our local club and he had five or six hits like in Schuetzendave's icon  but he misssed the others wide for a 236.  Start with trying to keep them all in the 18 ring and go from there.

Well I will ramble about it cause I keep track.  Score targets 2000 is a good score. 2100 separates the better shooters from the rest.  2200 is very good.  Best in the country may go 2300 sometimes, all time records are not much higher. Score breaker is wind or off shots. Limit the off shots 2100 is much easier to do. Mild conditon day makes a big differenc too. All I keep track of is score and off shots with a detailed log on why the off was off.

Far as group size. On our Club 200 yard Ram target Is what I shoot the most  20 inches high 40 inches wide. Larger head and Horn with two legs, but they rarely come into play. You want to put them in the 20 x 40 center of the steel . I generally keep 90 % of my offhand iron sight shots in 7 MOA, 14 inches at 200 yards. This from paint splashes in matches, paper target painted rams practice  Off shots are the ones than sneak outside of 7 moa when they do they are either way off to the right  on a bobble due to over hold or high near misses due to a fuzzy front sight.  Last 3 or 4 years my average all matches is bit over 36 hits.

Our club has a dozen guys with similar averages. Winner to also ran is totally dependent on number of off shots with one or two hits making the difference. High hit  was a 39 most matches are won with a 37 or 38 nobody has ever hit 40.  So the winners put high percentages into a target 10 moa high and 20 Moa wide

Scope matches on the ASSRA you don’t get as many eyesight misses but most have a tendency to over hold due to the better ability to see center.  Real key to shooting a good scope or iron score is see the spot pull the trigger don’t  wait for better.

Will post a picture of paper ram and Rimfire 100 yards same target in MOA Don't have one of the CF ram

Ten inches would be a good goal. If you can do that you're bound to make some good scores . Practice practice practice is in my opinion what is needed most.

You can talk about 225-230's all day but the reality is those are excellent/high scores that takes a great oh shooter having a pretty good day. OH is freakin hard!

Ramble some more,

Target equipment and match makes a difference in group size.  For example on indistinct targets like a Silhouette groups will be larger. Paint a black dot on a White Ram group shrinks because you have a aiming point.  Difference in resolution Iron to Scope gives you another minute of angle.  Weight of the gun trigger pull all make a difference. 

Major advantage of a Schuetzen is the palm rest allowing direct connection between gun supporting hand and hipbone.  Hook plate and high cheek piece settle things down too.

Found a Rimfire ASSRA 100 yard target from one of last year’s matches. Full Schuetzen CPA nothing else can be done with the rifle to raise scores. Not the best target not the worst, just happened to be in my target bag. Measuring, the 10 shot group was 2 ½ inches high 5 ½ inches wide. Centered up no off shots score 216. Wind error left and right accounted for the score. Put together 10 of those targets it’s a 2160 Hudson.  Not a easy thing to do.

Keep shots in 2 ½ moa elevation, groups nicely center up. If you can shrink the wind error to less than 5 moa you will have a good score.  End of the match score will depend on no off shots. Fellow that can shoot all in 4  or 5 moa will have a higher final score than someone that can hold 3 moa and pulls a percentage off.

Squaded with one of the top silhouette shooters in the country years ago, he gave me some good advice after the match. “ you will learn to hold the rifle better, for now don’t make mistakes  “

When I'm shooting my best OH, groups can measure and usually measure about ten to twelve inches.  I don't consider them groups. More like patterns. Most of the time I have one or two wide shots. All this about equations and radius and so on makes no sense to me.
