I'd be interested in the velocity you'd get with mild handloads. There was a 4" stainless k-66 well into my distant past that was pretty astounding with fart powered wad cutters. Hard to believe that accuracy came from a wheel gun with a shorter than 6" pipe... Regards , Doc Sharptail |

LGS had a set of Pachmayr grips & they make it fit my hand a lot better. Found my forcing cone cutter and did that while it was apart. I'll get out tomorrow & run more ammo through it. SW |

wonderful job , show us photos of the finished product when you get time , i am home till the 13th and will need a little entertainment between cleaning projects , hoping all goes back to normal after that but a bit of distraction can never hurt what ? |

I meant to do that today, but it took most of the day getting a care package off to Belgium. Turns out they won't ship hand sanitizer because it has a lot of alcohol in it. But after going home & removing it - then re-typing the customs declaration, it finally passed muster. The Easter candy, books and MAGA cap are on the way! SW |

thats OK , sounds as you had your hands full , they are really picky these days are they not ? some stuff seems really dumb in the big picture - fingernail clippers in TSA line ? im sure there is a good reason behind them that might make sense but "FOR THE GREATER GOOD" jumps up in my face when i try to say that out loud "COMMON SENSE" right after that , i know the founding fathers did not see today when they wrote it but what awesome foresight in the actual wording - now we just need lawyers that can actually read ......... |

Fitting /timing a barrel. Formula: 1" didvided by number of threads per inch = the amount to remove to do one complete turn of the barrel. Divide that by 3 (in your case you said 1/3 turn to line up) and that is the amount you need to remove to get sight line up. A little less stock removal say .002 -.003 will give you torque on the barrel. I do have the formula for torqueing a Mauser barrel if you need it. Did you check the forcing cone to cylinder gap? |

I knew there was a mathematical way to figure thread pitch vs distance, but math is my weak spot. I just did the cut and try bit - must have taken the barrel off 15 times before I got it just right. The thread pitch is very fine - it amazed me how much difference 5 file strokes would make, and I wasn't leaning on the file too hard. My closest friend was a self-taught machinist and math whiz... he could have told me how much to remove without batting an eye. But he couldn't have gone without chucking the barrel up and carefully machining it to spec. After cutting the forcing cone, I gave it another 3 file strokes & my automotive feeler gauge shows about .003" barrel/cylinder gap. I really shouldn't try stunts like this - I am NOT any kind of gunsmith. SW |

i would be happy with that but then im not the shootist you are , im aiming at 12"-18" square or rounds at that distance in my venue not a beer can , congrats i too would have guessed a bigger spread between the two , but then i have never tried it either , i tend to a 5 1/2" or 4 3/4" barrel length in what i shoot , i do have the 8" 1858 with the conversion cylinder but have only plinked with it so far not really tried it in a real setting , i had always thought it might be more accurate , i am pushing a 45colt through a 44 barrel , |

i would not be unhappy with those results , looks like success to me with that short barrel , as a CCW it should serve fine , you obviously have one for accurate target work , i dont have my chart handy for low left hits , |
