If he is still around he could elaborate.
Yeah, I'm still sucking air, if that is what you meant.
I am not sure what "impressive groups" are.
A friend took and posted the pictures without my knowledge.
Although it was long time ago, I think he chose the best target of that day,
and I remember most targets were worse than that.
I don't know what you want me to elaborate on, but
the gun that shot that target had few things done,
like a preventive crown job I did, very basic and straight forward,
and a nice trigger job a friend did for that gun.
I think it was said at that time.
In my experience, the hardest thing in accurately shooting the t97 is to overcome
the gun's tendency to move a huge amount during the locktime,
(and the reason to that is the original design of the firing system).
That was the reason it was so hard and painful to shoot it accurately.
To learn to overcome the gun's specific reaction, is to learn to hold
a gun steady in a different way than one is used to hold other guns.
For me it was a frustrating and physically painful experience.
At least for those who attempted it and succeeded,
fixing that flaw in design was not easy task either,
(finding a solution and proving it to work).
To make things clear, the gun used to shoot the target posted here
had the original factory (commercial) firing system
like any other T97 sold in Canada, with only a trigger job, as I said.
