I've run across a rare set of Krupp barrels for a graded Syracuse 12-bore; both tubes (28")have light pitting their full length. Don't know if they'd be worth the effort to clean up, but thought they could be a good learning experience. I checked Brownell's for barrel striking tools, but didn't see anything; perhaps searched under the wrong product name?
You need two things. A appropriate hammer, (or hammers) and an appropriate backing piece for within the bore. I caution you, the bore tool is the most important. You really have three choices there, a tapered slug turned to bore diameter, a sliding wedge dent remover, or a hydraulic tool such as sold by Brownell's. The hydraulic tool being the most effective when used right. You do not actually remove the dent by sole use of any of the tools, but by having the tool apply pressure to the underside and the tapping of the hammer actually raising the dent.
Brass or rolled rawhide are usually the hammers of choice, but I sometimes form a lead sheet over the dent if I decide to use a very small steel hammer I have. A layer of metal HVAC tape is also sometimes useful to protect the tube as well. A variety of hammers are usually found on Ebay.
I'm going to be striking several Parker sets shortly, I'll post a thread on the DIY forum.
