I have kept Winchester 158gr LSWCHP ammo loaded in my revolvers for defensive purposes. Some months back I decided to "roll my own". I wanted to duplicate to the old FBI load which mirrors the Winchester factory load.
After reviewing the few available LSWCHP bullets, I decided on the Speer bullet. While I had not seen the bullet up close, the photo on the MidwayUSA site spiked my curiosity. The bullet has three drive bands, two of which are wide. In between the bottom two drive bands is an area that resembles a shallow lube grove.
After I received my 500 count box from MidwayUSA, I did some measurements. The bullet weighs and average 158.4grs. the diameter averaged .3585". I ran a sample batch of bullets through a .358" lube sizer die, and was able to deposit lube in the area between the two bottom drive bands.
I loaded these bullets in .38 Special cases over 5.4grs of Unique, seating to an OAL of 1.462".
At the range I chronographed three cylinders full and the average velocity was 964fps with an extreme spread of 54.4fps. At 7 yards six rounds cut one raged hole, repeated three times. The last test was one gallon water jugs 10 feet out from the front of the bench. The bullet passed through four jugs, coming to rest in the fifth jug. This test was repeated three times.
All bullets expanded, and the average of the expanded bullets is .598" in diameter. Bullet weight loss was relatively light, averaging 3.1grs loss.
All tests were with a 4-inch 686. Inspection of the barrel after all tests were completed showed no leading at all. I believe the lube I added was the reason. Granted l shot less than 40 rounds during this test so maybe this is not a good measure of non-leading a barrel. However since this test was to identify the potential of a defensive round, quantity on rounds fired is not as important as expansion and placement.
