I have left T7 in for a week and a half with o problems. I just got a Lyman Flintlock Deerstalker and use Goex 2f. Is it ok to leave it or should I shoot it each day?
As long as you do not shoot the rifle, you do not need to clean it. You can leave it loaded if you like. Of course keep in mind how to insure that the rifle charge will not become contaminated and then fail to fire. If you shoot the rifle then you should clean it at the end of the day. The nice thing is, just a shot or two and the rifle is not really all that hard to clean.
Keep us posted as to how well that Deerstalker shoots. I have heard some great things about the rifle and its accuracy.
