Well the molds I made for my paper patch experiments did not work out well. I made them a bottom pour mold with a "push out" fitting on the nose. The size was right on but the nose was not smooth and while they worked fine at 100 yards, anything over that they looked like shotgun pellets! So I thought a bit and thought, can I size or swage them down to 0.438 from the as cast 0.448 which is the grease groove size and works great out to at lease 300 yards. I then noticed....hey I have a Harbor Freight 10 ton bench press sitting in the corner that I used for pressing bearings, etc on my race car years ago and I figured it could force a telephone pole up a nat's ***!
So I took a chuck of 6061-T6 and drilled a series of steps every 1/2 inch starting at 0.450 at the top and ending at 0.438 at the bottom. I used a piece of drill rod as the pressing rod and tapered it slightly. So I ran a few of the less than perfect castings through it and it took a bit of force but they came out smooth and the right size....0.438! Soooooo, I did a dozen and they all are the same size and wrapped them for a range trip next week. Right now it is 107 in my back yard and I live on the ocean so I plan to wait a bit but seems like this might do it?
I did order a 0.438 mold from Old West Bullet Molds so I should get that next week so I'll have several things to try out! They had some good things said about them on here so we'll see. I realize this is not a "true" swage but more of a sizer so please don't holler about my naming of it.
