Step 8 - Point Forming
I spoke with George Ulrich last week and he told me to cut down on my lube. Going forward I’ll use 0.5 grs per jar for jacket lubing. The cores will then be seated, the jar cleaned with acetone, and another 0.5 grs applied to lube the cored jackets. Since I still had enough lanolin on the jacket at 2.0 grs, I didn’t re-lube after core seating. Instead I went right to point forming. Here are those steps.
The cored jacket is placed on the punch and the press is actuated.
Some video of the point-up process:
Note how careful I am in guiding the thin jacket lip into the die. The final bullets are then measured for:
1) Weight – these by design land at 67.1 grs. I must’ve done good on core swaging because they vary by less than 0.1 grs over a wide sample population
2) Base diameter. All of them mic 0.2433”
3) Base-to-ogive. These are exactly 0.966” with no variation across those tested.
Here are the components involved in making these 8.5 ogive 67 grain 6mm’s. Left to right – cut core, swaged core, empty jacket, core seated jacket, and the formed bullet.
One of the neatest features of a Ulrich bullet is the heal. George grinds a slight radius into the core seating and point-up punches. The result is a straight base with no discernable pressure ring.
My boxed bullets. 500 count on the left, 1,000 count on the right.
This Saturday we’ll see how they fly.
