I actually did some bullet testing with some other bullets but included a couple 140 XTP which I have on hand. These were shot straight into bare wet-pack and I've attached the picture which speak for themselves. One is at max load for 38 spl using Universal and one is at max load for 357 magnum using 2400. Universal gets the same velocity as HS-6 but uses less powder. HS-6 is a really random choice for 38 spl unless you were also using it for a caliber it is actually suited for.
Now don't say I never gave you anything
