@GJM was kind enough to send me some Lehigh Penetrators loaded by Underwood for me to try out in some Clear Gel. In my post on the Double Tap’s deepest penetrator, I came up with what I hoped would be a substitute for testing through bone.

The Idea is to use 20ga sheet metal angled at 30 degrees to simulate bone or skull bone and see if there is any effect on penetration of deflection of the bullet's path. The sheet metal was placed in front of three 16 inch blocks of Clear Ballistics Gel.
Starting off with the .45 Super, I shot four rounds through an HK 45C with a 4-inch barrel. The first round shot through bare gel had a velocity of 1111fps and penetrated to 23.5 inches. The second round was shot just below the first through the angled sheet metal and hit at a velocity of 1087fps and penetrated to 18.75 inches. The third round was shot in the upper right of the gel blocks and penetrated to 23.75 inches with a velocity of 1094fps. The last round was shot through the sheet metal just below the third and it had a velocity of 1105fps and penetrated to 20.75 inches.
None of the bullets shot through the sheet metal showed any directional deviation from the impact. The four rounds had an average velocity of 1099fps. This velocity is about 100fps less then what Underwood’s claiming of 1100fps and about 100fps more than my handload of this bullet I tested previously. However, even with the increased velocity the penetration only increased by three-quarters of an inch from 23 to 23.75 inches. This load is also a little on the flashy side.
This bullet, at least in .45 caliber, still seems to suffer from lack of penetration depth even with the increased velocity. The sheet metal only slightly retarded penetration depth by about three or four inches.
GJM also sent me some to try in 9mm, 10mm, and .45ACP +P. I’m going to try it in 9mm next, then probably 10mm and .45 +P last.
