    If you have a mec super sizer I use that to hold my hull in place while I roll crimp on the drill press

    Looks like it's time to un roll some birdshot loads and make some custom ones. Buckshot is hard to find right now. Wax slugs. Mini shells are too short to cycle in pumps. Maybe make some custom 2-1/4ish inch shells for them to cycle properly in a pump. Get another round or two in the magazine. It would be interesting to see your take on some custom loads like that.

    I'm new at this. What benefit does roll crimping offer over the standard crimp?

    • @murphyfirearmstraining3630
      @murphyfirearmstraining3630  3 ปีที่แล้ว +4

      You don't have to get your column height perfect, so it's easier for buckshot recipes, or experimental recipes where your column height may be off slightly causing a poor crimp.

      Roll crimping is very consistent compared to fold crimping. Proper crimping is critical to allow pressures to build to reliable levels for a safe and effective shot. Consistency in crimp = consistency in pressures.

      I just add a little bit of vasalin into your roll turnover head, makes a better roll and you can roll as many as you like. I use a double pin,or a 4 pln roll over tool. Best regards from Scotland. Fred

      Or rub the outside of the crimping part of the hull with some wax.

      Less friction if you use some lube there and easily hold it by hand. 😊 and no need to preheat the crimp tool

    Don't you want 1/4 inch to rall crimp you have a hevey crimp won't it billed to much pressure bigger the crimp. Just wondering

    • @murphyfirearmstraining3630
      @murphyfirearmstraining3630  ปีที่แล้ว

      My experience has been that even a heavy roll crimp has less pressure than a 6 or 8 pount crimp. My load manual lists lower pressure for all roll crimps with the same load as compared to star crimps.
      There is a limit though, too much shell sticking up and your roll crimp will not do well.
      I hope that answers your question.

    For roll crimping you are supposed to have 5mm of heads pace u are far to deep for roll crimp

    Good video.
    Can you vary the length you leave to roll crimp, as long as it bottoms out? I was wondering if shorter would be better. It would certainly be faster.

    • @murphyfirearmstraining3630
      @murphyfirearmstraining3630  4 ปีที่แล้ว +4

      Shorter is better, easier to get a tight crimp. The beauty of roll crimp is that you don't have to have an exact height. Where as with the star crimp if too short it caves in, if too long the crimp will open up and spill your shot. That's why I exclusivity roll crimp buck shot loads. Hope that helps.

      @@bradesteve2077 not exactly. I can though. The way I do it is to use the shell reshaping tool (big aluminum cone) to get them back to round, then load and roll crimp again. I have a video using the reshaping tool (from BPI, called "the spin doctor ")

  • @keithosterkamp6207
    @keithosterkamp6207 หลายเดือนก่อน

    In your experience does the Spin Doctor work to reuse once fired slug hulls? Or is there a better option?

    • @murphyfirearmstraining3630
      @murphyfirearmstraining3630  หลายเดือนก่อน +1

      @keithosterkamp6207 that is actually why I bought it. After roll crimping slugs and buckshot I found it difficult to reload them. It does open and uniform the hull for easier reloading. It needs to get pretty warm to be effective.
      I have a video on using it.

    Can these be reloaded again after being shot? I’m wondering if this method can only be used once on a new shell

    • @murphyfirearmstraining3630
      @murphyfirearmstraining3630  4 ปีที่แล้ว +3

      Short answer is yes. These can easily be roll crimped again. They can be star crimped again, but that takes a little more work. I will eventually make a video of that process for folks.

      Almost all of my shotshell stuff comes from BPI - ballistic products incorporated. They sell roll crimpers, hull vices, the spin doctor, overshot cards, hulls, manuals, etc. A one stop shop for shotgun reloading and they have several free load data entries on their blog.

    What's that red Hornady machine thing by the edge of the table???? Is that a crimper as well I looked on hornady's website and could not find anything like that. Can you please tell me what that is and if it is a crimper where I can get it??

      That is a trimmer. It lets you trim Handgun and Rifle brass to any length.
      It is called the Hornady Cam Lock trimmer. Can be spun by hand or you can attach a power drill. Works well when you want to set a specific length to trim brass to.

    How about wad compression, with the roll crimp.

    • @murphyfirearmstraining3630

      You get lower pressures because you get less wad compression.

      @@murphyfirearmstraining3630 so I see your using one of bpi s wads. What if you went to one of the hard gas seals and some other wad with no legs. You said they were longer than crimped. Would your fit and function in just a 2 3/4 inch chamber?
      I used to use a 1 1/8 wad with 9 .32 ball or 00buck. With a foam filler and a over shot card crimped, for a low recoil 00 buck load. Using a 1 1/8 powder load , usually 700x around the barn yard. I found load data that in one of my books. That does trap loads and oobuck loads. When you measure the 9 pellets. It's the same weight for volume as shot being dropped

      @@sandsock so the 2 3/4 length is unfolded. Even if the roll crimped shell is longer, it will still chamber since the chamber is made for the unfolded length.
      Every load I have read for pressure shows the roll crimp with lower pressure than star crimp.

      It is just the way it's designed, I think it helps to smooth the edge a bit by rolling it inward. That's a question for BPI.
