GPR cleaning question

[n.h.schmidt]

J.A You must be on a mission and cannot say much about your true self.I know this from conversing with a known associate of yours a certain Dr. Stephen Maturin.
I would not recommend the removal of this breach plug. You will make the parting line between the plug and barrel look worse with every removal and make it looser too.
If you must ,mine came off very easily. I had the barrel in a padded vice. I had padded the breach and used a big crescent wrench. It was not tight at all and had no sealer on the threads

Jack,

I wouldn't worry too much about pulling the breechplug. It's a royal pain. You can clean the chamber fine from the muzzle end with the .35 brush. The water rinsing you have been doing has probably done a fine job of keeping the salts out, so I doubt you'll have much rusting. Probably just a lot of carbon and crud.

Jack. The one thing you can do now that you have pulled the breechplug is to use a drill bit, or chamfer bit to bevel the entrace to that flash hole. You say it enters at the high side of the powder chamber. Is there any way to lower it? If not, can you open it with a drill? The small oriface in the nipple is what prevents back pressure from blowing the breechplug apart, not the size of the flashchannel. I would be upset to fine a flash channel entering at the top of the chamber, rather from the side. Anything that can be done fo facilitate getting powder into the flash channel during loading would be my goal, as well as removing any burrs on the edge of the hole that might catch on a cleaning patch or jag for the powder chamber. :thumbsup:

I did check the dia of the flash channel.Its a wopping .135 dia. I'm good at this kind of thing and it don't look good to improve it much. Maybe drilling the flash channel bigger and retaping the hole for the clean out screw . n.h.schmidt

WEll, that measure just a hundredth of an inch bigger than 1/8" , and that is pretty small. That is why those flash channels clog up so often. I would at least chamfer, or bevel the opening from the flash channel into the powder chamber, and polish that end of the channel, to help cleaning the flash channel, from the barrel, with soap and water.
