    I performed several gel tests a while back using some bullets John Kort, aka w44wcf cast to his specs and sent me for testing.

    Some 42798 cast 75/1. Impact velocity at 50 yards was 1,162fps from a 26" barrel

    Expands just like a hollowpoint.

    The below lead bullet was one of the soft lead tests while the below jacketed hollowpoint was tested with a thumping load of 2400.

    Here is an example of lead bullets expanding just as well as jacketed hollowpoints. Once the velocity tapers off to a slow brisk walk, the bullets, especially hard casts...will not expand and will penetrate the broadside of a horse.

    On a side note, here is a slower designed 44 special hollowpoint used in the 44-40.

    Forget the caliber used and concentrate of the design and velocity needed for desired penetration.

    The Winchester JSP type design is a perfect design for hunting if you want a jacketed bullet. When fast, it expands like a hollowpoint....as it slows down, it penetrates deep.

    Can you post us some images of it?

    Also, what is the Mold Number for the Middle Boolit there which has the little "Nose"..?

    Thanks!
    Here's the revolver. Shown dirty from shooting, a .36 reworked to use .41 molds, courtesy of Mr. John Taylor.


    The middle mold is the Lyman/Ideal #41026 / 410026; huge lube grooves (good for black powder) and the nose tit is good fit for the ram.

    Good Cheer,

    Just for kicks you can try shooting your loads into water jugs. Water is of course more dense than flesh and will cause a tad bit more bullet damage than flesh (gel) but is close enough for government work.
    excited to see the results.

    With the same charge of powder the semi-wadcutter and round-flat point were best. The wadcutter was of course the worst.
    Any how, got me to thinking, the advent of smokeless and magnums, the introduction of designs other than the round-flat noses that had previously pretty much been the universal constant. It's interesting to look back at how things evolved.
    Absolutley,

    The wadcutters are fun to shoot paper because they leave a nice clean hole. For flesh I would certainly use the LRNFP or the SWC.

    Here is one of my hunting loads, it is the SWC but also makes nice clean holes in paper.

    Yeah, you bet. Also use bundled up paper soaked in water so long that it swells and all the binder turns to slime gel. I tend to collect the paper until I need it, then bundle it up and submerge a couple of days. Used lined up jugs of water to slow down boolits to recover from the .458 muzzleloader. Had three jugs and then a big box of shredded paper suspended behind. Was quite a show! And it worked.


    This was a soaked paper test block.

    How interesting!

    Does John Taylor do these conversions where I might have him do one for me?

    What a nice idea!

    I can only speak to conversions he has done for me.
    This one is a .40 caliber (reworked .36 caliber 1851). Uses .41 round ball.
    And I love it.

    It's a womderful idea...

    I do not have any .36 / Colt Navy Revolvers ( only a few .44s ) but, I'll get one just to have it converted to .41.

    I have an old Mold for a shortish .410 'Can of Beans' Wadcutter which would be perfect for this.
