Yes indeed, the sights and lock play a huge factor. From a sand-bagged rest, I have gotten under 4" groups at 100 yards with my Colerain barrel and iron sights.
One of the biggest problems I found with factory guns such as my CVA, TC, and Pedersoli "Blue Ridge" was the front sight post was massive. I mean at fifty yards compared to the black circle on the target the front sight post seemed large, and at 100 yards it was like trying to center a quarter coin on top of a 2 x 4. :shocked2: When I swapped out the front sights for thin, silver blades, the groups dramatically improved, because it made it easier for my eyes to be consistant shot after shot. In fact the year I did this for the Blue Ridge I won a stake cutting contest with the target being a 2x2.
The manufacturers ship these guns with robust, steel sights as they want the customer to get their rifle intact, and a thin, steel or silver, front sight post is easily damaged or snapped off in shipping. Further more, the rear sight on a facotry gun when adjustable my not be very precise, and a fixed rear sight may be more a function of how they contribute to the rifle's appearance, than how well they work. :wink:
The poor novice, doesn't often realize there are ways to optimize both the front and rear sights on their factory rifle, and when they don't get very good groups at the range, they get discouraged. If they don't have somebody who is experienced in BP shooting to give them a tip or two, they may not continue with the hobby.
