Isn't that just shooting for a group anyway???
I have two here, ( one for the young bloke and the wife has her fathers old one ), have shot about a dozen others and seen dozens of them in action. I'm not really that fond of them, but they do have a habit of shooting quite well.
Test shooting groups proves the accuracy, whether you want to shoot for score on a range or have peace of mind that the shot you take at game will pretty much land where you want it to.
I can't say that yours is typical oldbloke, or, how to make it more accurate aside from finding the right ammo for it. There is a few tricks to get a bit more out of them without spending a bunch of coin. Playing with the action screw tensions can make a fair bit of difference. I removed the one that screws into the barrel below the rear sight on my young blokes rifle, that made a big difference to it. However, the other one shoots better with that screw in place.
Also, have a play with lighter springs on the trigger, they are really basic and easy to swap out. I've seen them set up with the spring out of a biro, makes for a very light trigger.
