I have work with that over the last 3 years, with out going into long drawn out detail I hav come to the conclusion that too loose is no good and too tight will shoot much larger groups than just right. I believe just right can vary some what fromm gun to gun depending on barrel whip and polish especally polish.
If you can load it with one hand it is to loose if you want to pound on it it is to tight [notice I said want to] if it is in the middle of those two then it may be a tight group shooter if you are. I use to tech safty courses and it is my ezperance that only about 2 out of 3 people can shoot even close to minute of angle with out extensive training. Lee
