I haven't posted on this Forum much, but I've been making my own shot for over 25 years. My shotmaker is very similar to the Littleton, and I'm on my second one. When I was shooting competitive Trap and Skeet, I was making 600-700 lbs of shot per year, and shooting around 10,000+ shells per year. I still average 100 shells per week, just about every week of the year.
I just saw another thread about making shot on this Forum, and posted a reply there. I then read this thread, and felt I should comment on the following quote from BEAR.
"Regarding the littleton, if you can make the cooling system, screening mesch, you also make the melter. It is just a bottom pour Lee pot with a multiple hole funnel. I don't see the small metal flap as being anything helpful, except to keep lead from splaching back."
The Littleton shotmaker is essentially an aluminum pan over an electric (stove) heating element. The pan is mounted at an angle, and the bottom edge is straight and has a lip on the outside. There are 7 "nozzles" in the straight edge of the pan, and each nozzle has one or two holes in them that the molten lead passes through.
The diameter of the holes is critical, and that is what determines the size of the shot. The nozzles that I use make size 8 1/2 shot, and as near as I can measure, the holes are 0.015" in diameter (slightly larger in diameter than a single wire in a wire brush).
The molten lead passes through the nozzle and makes a sphere shaped droplet on the outside of the nozzle. The droplet then falls onto the lip, then rolls off the lip and falls about 3/8" into the coolant. The lip is lightly coated with welders soapstone to prevent the lead droplet from sticking to it. The drop distance from the lip to the coolant is also critical for making round shot.
The coolant that I use is liquid laundry soap mixed 5:1 with water. My coolant is contained in two stainless steel rectangular "buckets", one inside the other. The shot falls into the inside bucket which has holes in the bottom to allow the coolant to drain out when it is lifted out of the outer bucket. The coolant displaced by the shot drains into a jug to be reused.
The coolant temperature must not get above 150* F and the shot has to fall through at least 2" of coolant, or the shot will be deformed.
As I posted on the other thread, I then wash, dry, and tumble the shot in graphite.
My shot isn't perfect, but it's been good enough that I have used it to shoot many 100 straight targets in 16 yd Trap and in 12, 20, and 28 gage Skeet.
All lead shot is deformed when it is shot, regardless of the type of wad or shot cup it is or isn't in. The plastic shot cup only prevents the shot from contacting the inside of the barrel of the shotgun. The force of the shot pellets going from 0 to 1200 +/- feet /second inside the barrel forces the pellets together, and a flat spot is formed where the pellets touch each other.
When the mass of shot passes through the choke, the shot pellets are further compressed into each other, and that increases the pellet deformation.
Bottom line is, the rounder the shot pellets are, the truer they will fly, but they don't have to be perfect to be effective, and no lead pellet shot out of a shotgun is a perfect sphere.
And there's more to the Littleton than drilling holes in a frying pan.
