I recently bought some factory second 80 grain PSP bullets in 243. Given they’re rejects, I wasn’t surprised to find quite a few defects, mostly on the noses. I found a way to not only perfect the noses, but to also make a machine perfect meplat.
I cut a short section of 3/16″ copper tubing to fill the gap between the base of the bullet and the bottom of the chuck on my 1/2″ bench top drill press. I put that up inside the chuck followed by the bullet, nose down. I snugged the chuck down with no more than hand pressure, switched on the press and ran the nose of the bullet down against the table.
The friction softened the exposed lead nose and it curled out until the copper jacket of the bullet came down on the table top. That’s it. Switch off the press, take the bullet out, catch the spacer and repeat.
Below are two examples of defective bullets, the spacer and a finished bullet with a perfect meplat.
Here, you can see the bullet spinning in the chuck against the table.
And here is the finished product.
Since using these bullets, I have found that 36.5 grains of IMR 3031 and standard large rifle primers produces a sub MOA group.
I’d like to thank Michael Gorski of Titan Reloading for providing the bullets for this project.
