I dont have any HP molds, but wanted to try some. SO I loaded some cartridges with boolits, and used my brass trimmer, with a drill bit the size of the pilot holder diameter (0.152) and made some hollowpoints 0.100 deep.
Some are obviously offcenter, which should effect accuracy.
Anyone out there try this?
I was thinking of making a jig to align a drill bit of choice to the center-line of the boolit. Anyone try this?
