I have read all the posts and looked at all the sites for all the different components and there is a wide variety out there but has anyone on here actually loaded any of these and if you have what components did you use. My brass is magtech 20ga haven't decided on slug yet my bbl is USH 1-28 twist. I would even be interested if you are using plastic as I can get the gas checks that I need from cicle fly but am not sure yet on which slug or slug sabot to try first probably gonna use Herco as I have some on hand. One slug that shoot very good out of my bbl is the buck hammers. I am just getting sick of these high $ for 5 bullet deals. And I am sure I can come up with something cheaper and more consistent than what's out there.

When you figure it out let us know. Id rather put all that money in my gas tank. Those sabots are pricey :eek:

I ordered about $150 worth of supplies yesterday to move forward on this brass shell slug project went kind of over board and even though I have the magtech 20ga brass I bought 10 of Rocky Mountain Cartridge Co. machined cases (boy that hurt) and I didn't even get a kiss on the ear $5.20 each. Not sure if I will get them worked up as I find out on the 19th when they will cut my wrist and then rehab so it might not be done til late jan . Will post what happens. Kurt

The big brass cases is from Rocky Mountain Cartridge and is loaded with a cast slug of pure lead weighing 720 grains.

The bullet mold is from NEI and is a cut down mold for a 900-grain bullet for a .600 Nitro Express. My usual plinking load uses a FED 209 primer and AA5744 for a velocity of 1,000 fps. A better hunting load is to hollow point the slugs with a 3/8-inch drill on a lathe reducing the weight to 550 grains (1-1/4 oz). With 60 grains of 5744 the velocity is 1,330 fps in my TCR-87 with a 23-inch barrel. The barrel on my gun has the outside contour of a 10-ga magnum so with a 20-gauge bore is probably much stronger than most 20-gauge barrels, and the action is strong enough for a .416 Rem Mag. My gun is good for 20,000 psi so I am not concerned about pressure from this load. However, I contacted a technician at accurate arms to confirm my pressure estimate for this load. I told him that the length of the powder column was about the same as a .45-90 loaded with a 300-grain bullet and that a .45 caliber 300-grain bullet and a 550-grain .62 caliber bullet have the same sectional density. Therefore, at the same velocities the .45-90 with a 300-grain bullet and my 20-gauge with the 550-grain bullet would have the same pressure and he agreed. He said the pressure would be about 12,000 psi. I got the velocity up to over 1,500 psi but recoil was higher and I wanted a load that would be very conservative in my gun. Since my barrel has a 1-in-24 twist and can stabilize the 700-grain bullets, I think a 1-in-28 twist would be OK for the 550-grain hollow points. At 100 meters this load in my TCR-87 put 4 of 5 shots in about 2-1/2 inches. I use sabot slugs for deer hunting but shot one deer with the 700 grain load and one deer with the 550-grain hollow point load. Both died. I am thinking about loading sabot bullets in the brass cases. I got bullets and sabots from Ballistic Products in Minnesota. The sabots are slightly too large to fit in the necks of my cases. I pulled the sabots and bullets from Hornaday's 20-gauge SST loads and it appears they will fit, but that would not be a money saving process. I was thinking that I could substitute Hornaday 300-grain .45 caliber slugs for the 250-grain slugs in their SST sabots for a better balistic coeficient and increase the velocity to about 2,200 fps for even better long range performance. The brass cases have more powder capacity. However, I would be experimenting where there may not be any good pressure data to correlate from. Also, the 550-grain hollow points were not of pure lead, but a harder mixture. They seemed to lead the barrel where as my pure lead 700-grain slugs do not lead the barrel. I guess the harder mixture does not obturate to fill the barrel well at such a low pressure, so there must be some gas leakage past the bullet. Also, the hollow point broke apart on the deer I killed with it. However, the deer was bedded down and I shot it in the front of the chest and the slug went through several inches of spinal column. I thought the bullet seemed brittel rather than ductile like a softer lead.
