ill bet rice can do one also.. but i doubht they are going to make very light barrels. too much liability.. remember they have to have sights cut in, and dovetails for the pins beneath, and all barrels will have some runout.... i still wish i would have had my rear sight soldered on my .62, i have a tiny bulge there from the dovetail but it luckily caouses no problems.. the reason im posting is that the twist and rifling depth is CRITICAL!! too deep of rifling and youl be pounding the ball in with a hammer to start.. the bigger the diameter of the ball the tougher it is to start as your lead balls edge is more parralell to the bore, and more of its lead needs to be moved to start...... if the twist is wrong youl have to be using strange powder loads to get stability... the twist must stabilize the ball, stop the major burning of powder before it reaches the end of the bore, and be powerfull enough to do the job its intended to do, and not be so much power that it blows patches or is quite uncomfortable to shoot.. so you will need a barrel maker that is well versed in building all types of bp guns.. im pretty sure mr rice told me that a big bore should have wide grooves, and narower lands.. this is to make loading easier but it will still grab.. he said a .62 should have a slow twist. 1 /72 is bout right, and slower than 1 66 could have problems.. a big problem with big bores will be holding the gun properly.. if you have a 36 cal and hold it tight or loose the recoil will not affect the ball impact point much at all.. if you hve a .62 or 12 gauge and hold it lightly it will shoot quite differently than if you hold it tight.. with a light hold the barrel twist will rotate my .62 about 5-9 inches low and to the left from twist from a rest.. from offhand it will shoot high with tight hold as recoil pushes the barrel up becouse my shoulder is solid andthebarrel cant recoil back with the shoulder moving back with it... these problems are made possible becouse of barrel time, and extra ball and powder weight.. barrel time is what i call the time of a ball to start moving and then finally exit the muzzel.. black powder barrel time is much slower than modern guns. big bores are slower than small bores, usually, and have more recoil to create trouble.. dont get me wrong, i love a big bore bp rifle.. my opinion only..dave..
