I would listen closely too, if the conversation were about modern, bolt action, bench rest rifles using jacketed bullets, but it is not. The question was about breech seating, which is a technique used with great success for single shot rifles of the non-bolt action types firing lead bullets. The leading practitioners of this particular discipline have found breech seating to be a very useful and successful technique. If we were talking about crossbows, we could compare the benefits of carbon fiber vs aluminum shafts, if we were talking about fencing, the various types of epees would be in play, but the question was about breech seating, a technique for lead bullets in non-bolt action single shot rifles. All other information, while true, interesting, and historical, is outside the scope of the original question. A properly set-up rifle of the type under discussion will have a concentric chamber to the best degree possible by the gunsmith making the rifle, also a breech face and a receiver face that are fitted as perpendicular to the bore as possible (the former being no small feat with some rolling block actions. These factors have been shown to be beneficial with virtually all types of rifles. The chamber for a lead bullet gun will be cut to accept a specified case, but there will also (usually) be a special "throat" cut to accept the bullet as precisely and with as much repeatability as is attainable. The lead bullet is inserted using a push seater, plugged case or mechanical seater to the same depth each time, frequently even with the same rotational configuration each time. This method gives the best results for most current shooters of this type of rifle. I trust this answers the question of the original poster, and if not, please drop me a PM and I will try to help if I can. Regards, Green Frog
