45-70 Trapdoor

[alfajim]

Hi all, new to the forum. I am building a 45-70 trapdoor from parts from the 1883-1884 era. So look to connect with other trapdoor owners and shooters.

The barrel is in very good condition with well defined lands and grooves. The edges of the lands are sharp with a nice shiney bore. The only bad part of the barrel is the muzzle it is pretty rusted for the first 1/2" to 5/8" so may not be usable. Will work on cleaning it up to see.

I was at first going to shorten it to 30" but after browsing the forums I would like to keep it as long as possable so 32" if I can and keep the original front sight.
I have the Buffington rear sight is this good enough to use for long range or will I have to get one of the tang rears like in Quigley?
Any other advice or suggestions from other trapdoor owners be appreciated.

Jim
