I'm just in the process of aquiring a 1901 production year late 01 or early 02,that doesnt seem clear. Anyhoo,I'm assuming it to be the standard issue barrel. A chum who I trust my life with when it comes to gun condition has told me the bore is GREAT,and the gun is as tight as an eagles ???? in a power dive. I know I just can't roll up some standard loads,however the guns main selling feature at the time was the upgrade to smokeless, so I'm assuming that I must be able to take it over the black powder levels slightly...Any thoughts
