Rifle arrive today. Cone u/s and the hammer is a replacement, looks the part but does not hit the cone. A trip to my blacksmith shop, removed the old cone, happened to have a new one of the correct type handy. l put the hammer in the post vice, heated it up and adjust the hammer a number of times till it now contacts the top of the cone in a proper manner. Snapped a few caps, gave the bore a good scrubbing. There is a little light pitting here and there but the bore will come up fine. It is rifled for patched ball.
This rifle is quite light, 6 1/2 lbs, it is also quite short. The twist is quite slow, maybe 1 in 60, narrow lands and grooves so patched ball. Looks like my .490 ball and a thick patch will be the go. Daryl if you see this post before this Saturday, what sort of charge? I am thinking of starting off with 55 grains of FFFg. I use 90 in my Missouri Plains rifle but that is an inch and a quarter across the flats. This barrel is quite light. There are no numbers on the rear sight leaves. So might start off a 30 yard off the bench. I imagine this light rifle was for shooting Deer in parks in England, but likely Kangas etc her down under.
