  3. Bart Vermeulen on October 28, 2021 at 8:35 pm

    Just scrap the gun or give it to a museum, is my opinium. Why shoot it.

    His voice immediately reminded me of that dukes of hazard remake a few years ago and I was not able to think of anything else while watching.

  17. Paul Bruneau on October 28, 2021 at 8:58 pm

    Ok hotshot, now let’s see you go to a smaller caliber

  21. jim kurk on October 28, 2021 at 9:02 pm

    so who did he send it to for the rebore?



  22. Anthony Williams on October 28, 2021 at 9:04 pm

    Would have preferred a little bit of info about the proofing process to ensure the barrel will take the increased pressure but otherwise very informative, never seen a rifling tool before and still no clue how it works but honesty not what I was expecting it to look like

    What’s this, the prequel to Breaking Benjamin?



  24. willy kanos on October 28, 2021 at 9:07 pm

    For those who are interested Delta Gun Shop no longer does reboring. Jim passed away a few years ago.

    Great video!

    The real trick is reboring a gun to a smaller caliber.

    Me: "Aw yeah, I’m going to be a REAL GUNSMITH by installing this drop-in trigger into my AR"
    Midway: "Yeah that’s cure"

    " Give it to someone who knows what they’re doing" is great advice ..



  32. Richard Hungwell on October 28, 2021 at 9:14 pm

    That’s a really cool process, but I can’t help but think it would probably be more economical to just get a new barrel.



  33. Evan Harrison on October 28, 2021 at 9:14 pm

    You kind of jumped over the boring parts.



  34. E C on October 28, 2021 at 9:15 pm

    "It’s a good, solid rifle, and I’d like to shoot it" I love that quote



  35. Notorietypulp on October 28, 2021 at 9:16 pm

    I always wondered how they made plumbuses



  36. Patrick Radcliffe on October 28, 2021 at 9:16 pm

    Going to all the trouble of reboring the gun for a new caliber, at that point may as go the full enchilada and reblued it. My take is all the value as a antique is gone when he rechambered for .357, may as well make her the bell of ball.



  37. stuarth43 on October 28, 2021 at 9:17 pm

    you said that you reamed the chamber in 100 thou steps, this is 2.5mm, have you got yoit math right



  38. Floyd Andrews on October 28, 2021 at 9:17 pm

    Wow!

    Larry has some neat tools in his garage!!



  40. grayfox evans on October 28, 2021 at 9:18 pm

    they only show some little bits of the process of re calibrating the gun from 22 cal to 357 of the barrel up to the firing pin bcuz of youtube law standard but still informative and also quite frustrating at the same time



  41. kn0t on October 28, 2021 at 9:19 pm

    Hi



  44. cal30m1 on October 28, 2021 at 9:23 pm

    Aren’t you concerned the chamber pressure of the 32 rim fire is considerably less than the chamber pressure of the 357 magnum?
