    Default .577 Snider load development -the first phase.

    Good day to you members.
    My good friend Herman Nel own a .577 Snider. He commenced on a journey to develop a load for the .577 Snider. Herman enlisted the assistance of Hansie Minnaar ( Steward Bullets)who took over Stan Steward`s brass/ bullet fabrication.
    Hansie Minnaar made brass and cast bullets for the .577 Snider owned by Herman Nel. Hansie and Herman did a chamber cast on the .577 Snider to determine the bore diameter of the rifle.

    Recently , while visiting Herman Nel for another building/brass casting project we set out to see how good grouping can be shot with the .577 Snider.

    Herman commenced by paper patching the 420 gn hollow core bullets:
    The bullet swage block and paper for paper patch...


    Paper patching the bullet:



    Paper patched bullets:




    The paper patched bullets are dunked into a mixture of beeswax/olive oil, seated and then the whole bullet /paper patched surface is dunked in the hot liquid again:


    Excess wax is removed by thumb nail to ensure a tight fit in the chamber:


    Fit the chamber :


    The shooting range on the farm, back stop is extremely dense potters clay:


    Herman Nel shooting at the target:


    Ruan and me did some shooting as well , to see if a good grouping can be achieved ...



    We did manage to get acceptable groupings. One of the problems was that the bullet tend to tumble with the first lot of loads that was develop.....these following pictures shows the tumbling had stop with the new loads and paper patch bullets. This photo indicate a straight line penetration, extremely deep penetration since the potter`s clay is extremely dense and hard .

    What is evident as well is that the bullets Herman shot is extremely hard lead as well since deforming did not occurred when deep penetration into the dense clay took place:

    This is the distance the bullet penetrated..at least eight inches into this dense potter`s clay wall that is the back stop..
    The bullet lodged in the clay...


    The bullet`s path of penetration:


    Distance of penetration/wound channel:


    .577 Snider bullets retrieved:


    Conclusion:

    We all got good groupings at seventy meters, but everyone who shot this rifle concur that the sights is not up to standard and therefore Herman Nel will build a ghost ring aperture sight for this rifle and a larger front bead to enable him to see the sights better and increase accuracy.

    Phase two will be about the designing of a ghost ring and front bead to increase accuracy....

    I stand to be corrected , it was 70 gn of FFFg it is the only black powder ( priming powder) he has currently, Herman will purchase FFg and Fg for a future load development .We are still working on a better load development...so the FFg /Fg will surely assist in the load development...

    Maybe I should give some info regarding the .577 Snider rifle:

    The .577 Snider cartridge was a British black powder metallic cartridge, which fired a 14.7-millimetre (0.577 in), 31-gram (480 gr) lead projectile, primarily used in the Snider–Enfield rifle.
    Early .577 Snider cartridges were made from paper, with a metallic base and primer, but later commercial cartridges were made from drawn brass, much like modern small arms ammunition. The .577 Snider cartridge was eventually replaced in service by the .577/450 Martini–Henry cartridge in the 1870s. The .577 Snider cartridge is considered by most commentators to be obsolete, with large scale commercial production having ceased in the 1930s. However, as of 2012, cases, bullets and cartridges as well as others of the .577 family are available from Tenbury Guns Limited in the United Kingdom. New brass can be formed from a 24 gauge hull and reloading dies are available from Lee. As of 2015, Kynamco in the United Kingdom and Bertrum in Australia are also producing ready-made brass.

    I noticed that the paper-patched cartridges didn't seem to be crimped tightly to the bullet. (At least it doesn't look like it in the photos.) Is that the case?
    If it is, does the seating die have case crimping ability? If crimped tightly, it would allow pressures to rise and perhaps give a constant pressure which should contribute to better accuracy and very little variation in velocities.

    As I understand paper-patching, it is to give a better fit of the bullet to the lands and increase accuracy. Could the same thing be accomplished by casting a softer alloy by adding stick-on wheel weights to the lead mix and swaging the final product to produce the same thing? The softer alloy would also allow for more expansion in a hunting situation. It would also allow the hollow base to expand somewhat like the "apron" of a minie ball and seal the bore better.

    Sorry for the run-on but new things kept popping into my head as I was typing.

    You are quite correct. The bullet lead composition is to hard, I am sure it can be use on dangerous game ...Herman is going to use a softer lead composition , for a tighter grip of the rifling, this rifling is a three groove Withworth rifling.

    The paper patch piece shot out of the rifle already show a print of the grooves on the paper.

    Herman is currently busy making a die set for the .577 Snider with Hansie Minnaar assisting him.

    Gert been meaning to ask when I met the right person, I see hear about paper and cloth wrapped bullets - two questions.
    First - why not just have correct sized bullets as apposed to correcting size with paper ?.
    Secons _ i always wonder would this paper thin lead sheeting you get not be a better wrap than paper. Surely it would seal , bite , engrave better than paper and its more engrave able malleable.

    Good day Treeman
    Always nice to hear from you.

    First - why not just have correct sized bullets as opposed to correcting size with paper?.

    Treeman, it is everything to do about traditional/authentic/as close as the old people did it their way, as well as the Martini Henry and other timeline rifles like the .577 Snider was design to shoot/ work that way accurately ( perspective) .We work with bullet molds that not usually have the exact print/size the bullet we shoot in our rifles. I believe when slugging/casting your chamber you can get a bullet that fit exactly the rifling of your rifle and make a old to fit exactly the rifling of your Martini Henry or a black powder rifle. Through swaging your bullets you can get to that point as well

    We participate in the 1800 Era black powder hunt, we need to re-act bygone times/behaviour/living/hunting therefore we need to shoot the rifles accordingly.

    It is like shooting a Martini Henry with Sonchem powder is just not the same as black power. The sight/smell of black powder is something special.

    Secons _ i always wonder would this paper thin lead sheeting you get not be a better wrap than paper. Surely it would seal , bite , engrave better than paper and its more engrave able malleable.

    The thickness of paper is determine by the diameter/circumference of the bullet. Usually you work on 2(bullet diameter) x 3.145 , the paper need to wrap around the bullet for two full turns. The angle you cut the two ends of the paper is 30 or 60 degrees. Through trial and error , airmail paper seems to work the best..but normal printing paper works fine as well depending on the diameter of the bullet.( Herman use it currently)

    I do not know about the thin lead sheeting you mention, but any manner to get these old rifles to shoot accurately to hunt with will be welcomed. It maybe worth a try to use the lead sheets..if the bullet size allows for it…

    I need to commence shooting/re-loading the Martini Henry I am going to use for the next 1800 Black powder hunt as well. I will be using paper patching bullets as well.

    Probably only if you travel back in time to the 1800’s. If you own an old Snyder chances are you’ll have to load for it.
