    I have just begun to get serious with this slug, and loads. I will be very interested in some of the other members loads and componants. So far, the only load I have compiled, from my Lyman shotshell book is with a Remington STS case, a WAA12 wad and 25 grains of Herco. I fired these in a smooth bore, cyl. choke. Accuracy at 50 yards was not acceptable.
    I am going to make a die to punch out proper sized card wads to go underneath the Lyman slug itself.
    I have swapped out my bird barrel with a Hastings 20" rifled barrel, and will be mounting a Burris 2x7x35 scope in a day or so.
    So fellas, lets post some tried and true Lyman Sabot Slug loads.

    I've only shot a handful of these, just enough to sight in the red dot on my saiga12 so i cant tell you what they group like out of the 17" barrel.
    but they had a nice brisk recoil
    i've since loaded the rest i had cast.The recipe i used is: winchester aa hull, 35g of 4756, a waa12r, and crimped not rolled as i read somewhere a roll crimp with these slugs can rip a petal off the wad causing poor accuracy, maybe a stiff overshot card would fix that if you want roll crimped.

    Do a search here for fullbore slugs. You want to pursue that
    course rather than the Lyman 525

    Carryacolt, so do I.
    I have not researched full bore slugs. The little bit of information that I have run across, states that bore leading will/may be a problem.
    I have however bought a small lathe this last summer, and want to get a blank Lee mould block and cut a cavity with a better BC than the Lyman sabot slug. I would like to cut a cavity that would be more to a black powder paper patched design, with a non-tapered shank and round flat nose, and the diameter of the Lyman Sabot Slug. I could still use (the) wad, or a different wad to suit the load. I realize that the weight would be more than the Lyman. The only problem may be the length of the boolit and it's stability with the rifling twist in the Hastings barrel.
    The original British paradox slug was fullbore diameter, short and squatty but it is (was) however designed for close in work for dangerous game. The paradox gun, (at least the one I read about) was smoothebore, except for the last few inches, to spin the paradox slug. The idea was to shoot shot loads, AND slug load efficiently. Very interesting concept. Something like a rifled choke.
    The more things change, the more thay stay the same. Eh?
    I have seen other slugs on this forum and others that resemble a truncated cone handgun slug. The taper at/towards the ogive was short, with what looked to be a straight shank. The slug itself also seemed short and squatty. Things just look out of proportion for the poor old 12 guage slug.
    Any thoughts? Anybody?

    Gunaholic:
    I did find a load in my Lyman book for 30 grains of Herco with the WAA12 wad and the Lyman slug. The
    loads sounds very close to your load of 35 grains 4756.
    I loaded a few of them up yesterday. I am going to mount my scope today and run out to the range and give them a try. I will Chrony them some other time.
    I will let you know how they shoot.

    The load (30 grains of Herco w/WAA12 wad) under the Remington Unibody SP heading, is the load that I tried out this afternoon. I weighed the slugs, and the average of five was 508 grains. The alloy must be a little on the hard side.
    I had to mount the scope, and away I went. I had loaded 8 rounds yesterday.
    I started on 2x at 25 yards to get the scope sighted in. The first shot went 4" high from X, and 6" to the right. I started
    kranking. The second shot went 2" high and 2" right. The third shot went into the 2" center circle.
    I moved to the 50 yard line, and adjusted the scope to 4x.
    First shot hit at 10 o'clock on the inside of the 2" circle. Second and third shots touching at 6 o'clock inside the 2" circle. 4Th shot cut the first hole at the top of the 2" circle. 5th shot touched the lower two shots making a perfect clover leif.
    So, the 5 shot group was approximately 2" center to center. Thats not too bad considering the terrible trigger, not using a rear
    sand bag, and the first load I've made up for the rifled Hastings barrell. I believe I am going to like slinging thes great big slugs.
    Oh yea, the recoil was very tolerable.
    Keep all the information comin fellas. Good loadin and shootin to you all.

    Please keep the data coming. I just cast a bunch of these and haven't started loading anything yet. I'm glad to see this thread.

    dn & lj, 12/17/12

    Over the past couple of years I've tried to get a number of slugs to work in my smoothbore Remington 12 ga. Marine Magnum with a Leupold 2-8 scope. I've tried BPI's shuttlecock (450 grains) and Foster slugs (375 grains) and their Gualandi DGS slug with attached wad (491 grains). I also put a lot of time and work into the Lyman 525 grain slugs. I've tried many tricks that some posters here and at www.shotgunworld.com have used with some success. I've tried different hulls, powder loads, different crimps ( 6 pt, 8 pt, roll), different wads and shot cards(20 and 12 gauge). I've tried full length wads, and ones with the petals cut part way off and all the way off. The average groups were in the 4-6" range at 25 yards, clearly unacceptable for my short range pig hunting. The only exception were the Gualandi slugs which would shoot cloverleaf groups at both 25 and 50 yards (0.84" - 3" groups). Since these were expensive and had to come halfway around the world (Italy via BPI) to reach me I wanted something more available.

    The answer was a fullbore slug. I slugged my barrel and ordered a semicustom slug mold from www.Accuratemolds, a 770 grain thumper with two conventional lube grooves. I ran this through a Savage rifled barrel made to fit the Remington 870 (amazingly it was a drop-in fit). After a lot of helpful advice from here and SGW I found a load that puts them into 1" groups at 25 yards with a velocity of 954 ft/second. I've only put it through one 120# male pig so far but it went in the right chest and out the other side leaving two great holes for blood trails. The pig just stopped and lay down. The shotgun bore has never shown any leading but there is some occasional unburned powder flakes in the barrel.

    If you've found a load that gives consistent 2" groups at 50 yards with your Lyman 525 then you're ahead of many of us. Good luck.

    the first load I tried from the Data that Lyman supplied with their mould gave me 4" groups at 50 yards. I will check my records for the exact load, I know it was the old style WW-AA 2 3/4" cases, win red wad.

    oldandslow:
    Remember that I did shoot that group with a hastings rifled barrell. As I stated in my earlier post, I did not get acceptable results with my smoothbore barrell, and I figured I might as well just get a rifled barrell rather than get totally frustrated at trying to make all of the different balls, sabot's, powders and hulls work. Besides that, I think it was cheaper in the long run.
    Merry Christmas to you also sir, and to the CastBoolits.

    This load works well for me:

    Rem STS hulls
    Win 209 primer
    WAA12F1114 or Claybuster clone wad
    2/3rds of a 1/8 inch 20 guage card wad under the slug
    Lyman 525 slug
    22.0 grains of Unique
    8 fold crimp

    The card wad was cut to 2/3rds of its original length because I could get a better crimp with that rather than a full 1/8inch card wad. I also feel that the card wad will keep the slug from cutting into the F1114 wad and causing unstable separation downrange. Anyway it works for me. I get 2 inch groups at 50 yards and on a good day I can get 6 inch groups at 100 yards through my Mossberg 500 with rifle sights (cylinder bore).

    I've shot this slug for quite a few years out of a 12g ultra slug hunter
    2 3/4 federal gold medal hull
    federal 12s4 wad
    win 209 primer
    45 grains blue dot
    Back fill the slug cavity flush with hot melt glue this keep the wad from pushing up the backside and take a file and lay the slug on it side and knurl the edges this will grip the wad a little better for spin. this load will stay on a 3 inch dot at 100 yards. The only problem that I have is with plastic fouling after about 6 or 7 shot that starts to effect accuracy. These slug just hammer deer on a good chest shot it usually bang flop.
    Another good load/info is the 3 inch here

    Shot some of these today using an old mossberg 500 with smooth bore 24" Slugster barrel--all loads 2 3/4" -- remington high brass 1/4" base wad shells, remington primer, 33.5 gr herco , DRA12114 wad. about a 8" group of 4 at 50 yards mv was 1418-1453

    with new Fiocchi high brass shells fiocchi primer, 37 grains of longshot, Federal 12s4 wad. got the group down a few inches seemed a little better but it sure was no tack driver. mv was just over 1500 fps

    this test was not very scientific but what i found was the slugs sit flat in the genuine federal wads and the slug did not seem to sit squarely in any other wads i have including waa12, waa12r, dra12f114 a down range duplicate of waa12f114, rp12 and rxp12.

    i plan on figuring this out further through the summer maybe what is needed is a rifled barrel. any and all suggestions are appreciated
