I will have to start practicing less then too Bob.

Full time to maintain once you get there.  It's a lot easier to keep them all in the red on the iron target than the scope target, Joe. 

Being raised on the farm and working construction I was always in good enuf shape to shoot the hundred shot and a few other offhand matches if I had enough time in  a day. And I can hold center on the 24, 25 ring for several seconds, but the trigger never seems to work    I hate it when that happens.     I think having too much of life getting in the way of consistent practice  everyday is why I gave it up when I was close, plus this is supposed to be fun.     Not work. 

I'd never enter a $100 match, I'd get too nervous if I got close.  One day I shot a 25, a 24, a 23, another 24 and another 25 in open relay at the Icicle .22 RF at Tacoma. I thought I hope somebody notices I'm shooting offhand  because they will never believe it. I asked someone on the next bench to be sure.  I returned to shooting and shot around the edge of the paper 

You got it Fitz, practice practice, practice.  Too much work 

My ranges are all about 20 miles and 35 minutes to an hour of more depending on traffic.

I did shoot an air rifle a little, but it is illegal to even shoot a BB gun here 

When some of the neighbors at range in Tacoma said someone was shooting after hours we tracked it down to an air rifle.  It sounded just like a .22.  Since BB guns are illegal I thought it best not to be shooting something people would mistake for a .22.  One neighbor called my wife to complain about me shooting in the back yard when there was highway work in the area.    all bangs are guns, don't cha know?

Still prefer and mostly use irons, but have ended up with a few old Weaver K-1 scopes for informal offhand practice at times on limited 100yd ranges.

To answer the opening question....
Yes, I practice offhand. That is the only way to win or place. And I care, so I make time.

Limited by 100y only? 
In my opinion, distance has nothing to do with getting better. 99% of getting good is brain and muscle memory. In other words, training until you can't get it wrong. 

Light free weights are good too, Especially as we seniors age! 
How bad do you want it?  It is a choice.

Air Arms TX-200 outside the shop at 20 yards. 
50 meters 22rf on scale paper chickens.
100yards on 100 yard 25 ring target with both RF and CF.

Here is one way to get yourself to shoot more...
The WSU forum has a "for fun offhand match" 100y, 25ring, any rifle, any sight, any chambering- internet match. Two 10 shot targets.  It is drop in so, start any month.
No rules - just your honor. Photograph your targets and post them.

Turn out has been small - odd - anyone can do it.
For added fun, post the picture of your rifle too.  It is fun to see the rifles people use! Almost like being there..

Okay - shameless offhand shooting promotion over.

CW, I looked around over there a bit but did not find for fun offhand match.  Do you have a link.  Google didn't find it either.

WOO HOO!   
Somehow in there is an oxymoron if ever there was one!

Yes, for some people, getting them to shoot offhand is much like getting a little kid to eat brussels sprouts!
