Bought a boito hiker from frontier and got sticker shock from the cost of 410 Buckshot loads. Approximately 2 dollars each. Fireformed with 4.9 grains of clays and a case full of cream of wheat topped with a piece of toillet paper. I had wrapped the casing with masking tape in order to align it in the chamber. The boito was capable of launching the TP to about 30 feet. First fireforming made the casing somewhat useable.
I then loaded the casing with 3.9 Grains of clays and 4 38 caliber round balls 82 grains each. Plus some felt pads that I bought from Canadian Tire. The second firing with the lead balls blew the casing out to fill the chamber.
Please note that no gunnutz were harmed during any of these experiments. Also for anyone thinking about making a cartridge with a regular bullet for a 410 it probably will not work. I spent 50 bucks in a mold and 40 caliber factory crimp. The crimper ruins the 410 casing and a 39 caliber bullet necessary to pass though the choke will not remain seated in a 410 casing. Been there done that.
