mcgiiver The tapping with a rod works wonders, more so in the direction from breech towards the muzzle, to break the bonds of the matching threads. If you have a 3/8" square already cut in the plug, then I would suggest an impact tool, either the manual one which you hit with a hammer or an air/electric one. Pretty sure the manual one will work. Plenty of Kroil, obviously.

gene_225 I haven't. We have both been busy and we have had other priorities.

mcgiiver Did you ever get the plug out?

gene_225 He has access to a cnc machine. That's as much as I know about how he did it.

mcgiiver I would not try heat, you may very well lock everything together even worse. With Kroil, or similar, in there, I would try alternately tapping the breech plug from the muzzle using a close bore fitting metal rod and brass cushion on the end, and a brass drift punch from the breech end. You have to tap a lot repeatedly and fairly hard, but not so hard as to mushroom the breech plug. A removal tool can also be made by using an appropriate sized 3/8" drive socket with the end ground away to form two close fitting pins. tedious work but can be effective.

How did your buddy cut a square hole in the plug?

If the breech plug is already destroyed, try using the repeated tapping and an Easy Out.

Thanks Tim, as I mentioned earlier, I am somewhat challenged when it comes to search engines, etc. I appreciate your help.

Chainsaw Don't know if this will help or not but recently purchased a similar problem child and was amazed at what Ballistol did to remove the BP and also clean the breech and barrel. Ballistol has worked wonders in black powder firearms. Though YMMV, Good Luck!

Probably, I just felt uneasy about mine even though the threads don't have any force on them (the back of the breach plug is against the receiver). The rust bothered me.

gene_225 It's on the internet, but I think it's also on this site. Look for both/either H&R Shikari and/or H&R Model 155 Shikari.
