I have a Lilja tight bore on my silhouette small bore and I wouldn't order another one. It is really hard to bolt the action from the shoulder and if you are called to stand down and make your gun safe, you can't extract the round. You have to get the match director to let you fire the round then it will extract fine.
This is not just on my gun, I have seen others have to do the same thing.
I can't tell if it is any more accurate or not since this is the way I ordered it new.
