Theories on this Charger Loader?

Yes, the rifling does appear worn. But it is seven groove which indicates metford rifling. I took it to the range last Friday and was surprised with how well it shoots. I fired this 10 shot string (1st round sighting) and put the next nine rounds into a respectable 2-1/2 inch group at 100 yards with handloads off of sandbags. Not too bad for a 125 year old rifle. I did notice I had so seat the bullet way out to get respectable groups. There is a fair amount of throat erosion.
