    Barrel residue

    Rat's not the only one using Hoppe's #9. I like to saturate a brass bore brush with it and do a thorough scrubbing. I follow that with some TC Bore cleaner and patches to remove the "gunk" and then flush it with hot water and dish detergent followed by clean hot water. I run a dry patch, then...

    breech plug face question

    Metalshaper, I think I answered the first question myself. Upon further inspection, the hammer is not what is keeping the breech plug from seating itself up to the threads. I believe that it's a slight imperfection in the hole in the action. Both plugs I have stop at the same place. I...

    Wd-40?

    I know a Gun Shop owner in Virginia who has banned WD40 from his shop. His theory is that it can cause misfires because of its penetrating abilities and the potental effect on primers. As stated above, this effect is more pronounced on modern weapons where oil is not removed. Special care...

    breech plug face question

    Metalshaper, I'm looking a my H&A action from Blue Grouse (see my thread in the Builder's bench section - Jimbo's Underhammer). I have 2 breech plugs for it. One came with the action and the other I ordered from Bruce to accomodate the threading of a GM dropin barrel (which I...

    Opinions Needed on 54 Cal...

    Mike, I did what Hillbilly recommended and went with the underhammer. My .54 is being built and it will look something like this when it's done: I also need a scope, but will use quick-release mounts for when I want to use the action-mounted peep sight/ghost ring. I don't like...

    Need advise on .62 smoothebore

    I'm having a custom underhammer rifle built (see my thread in the builder's bench section - Jimbo's Underhammer). I have ordered a custom .54 rifled barrel from Ed Rayl. It's a tapered octagon to round starting at 1.200" to fit seamlessly with the octagon receiver and ending up round at...

    did something stupid tonight

    Remove the nipple or touch hole liner, pour a little FFFF powder in, fully seat the Jag, and shoot it out. That's the easy way. Jimbo

    OK, got a flinter. Now what?

    I've got the same model Renegade that you have - got mine used about 5 years ago to hunt the PA late season. I use Hornady roundballs, Thompson bore-butter patches with 75 gr. Goex FFF. I can hit an 8 1/2 x 11 inch paper offhand at 100 yards, and have shot a deer every season with it. The...

    Slug for lapping

    Jimbo's Underhammer

    Choosing the loads 1. I'm not real crazy about sabots. I never had bullet seating problems when I shot PRB or TC Maxi-Hunters. Then I bought that durn Omega. The first time I shot it, I used 777 and Mag Sabots. I felt like wrapping it around a tree. I've since worked thru those...

    Jimbo's Underhammer

    BS, Thanks. I talked to both the gunsmith (Dave Stotler) and the barrel-maker (Ed Rayl) and they both agreed that this is the way to go. The new configuration is: The anticipated delivery is September. The cost is $220 plus $35 for oversize (over 1 1/8 ")plus the charge for the 8...

    Octagon to round tapered rifle barrel

    Here's a link to some Octagon-to-Round barrels at TOTW. Colerain octagon-to-round They are longer than yours and were used on early 1800's military flintlocks built at Harper's Ferry. I just ordered a custom octagon-to round from Ed Rayl for the underhammer I'm having built. (see Jimbo's...

    Jimbo's Underhammer

    That will be barrels #2 and #3. I intend to have him build a .62 smoothbore for Turkey Hunting next Spring. Later on, I'd like to have a 1:66 PRB barrel just so I could make more noise and smoke than anybody else at the range! I can get them built in the same configuration without having to...

    Jimbo's Underhammer

    BS, Thanks for pointing that out. Yes, I have concerns about the weight. When finished, this rifle shouldn't weigh anymore than my .50 renegade flinter, which I carry during the PA primitive deer season. The underhammer action is very light, and the bigger caliber plus the taper should...

    Jimbo's Underhammer

    Choosing the barrel 5 I talked to Dave, my gunsmith on Friday. He thinks we should order the barrel from Ed Rayl. We talked about changing the configuration. The H&A underhammer action is octagonal and mikes at 1.200" across the flats. We want to make the barrel seamless with the...
