Speer made some truly excellent "half jacket" (about 3/4 actually) SWC bullets, a 146gr HP and a 160 SWC in .38 cal.
Repeatedly and clearly stating, (including a note in the bullet box) that there was a MINIMUM velocity for those bullets and that they should not be fired at less than that, because the jackets could separate.
Some folks didn't listen, as usual....
ANY of the old "cup and core" pistol bullets may shed their jackets in the barrel if they are pushed too SLOWLY. The further up the bullet the jacket goes, the less likely it is, but even slugs like the Remington scallops can do it.
The answer is simple, and obvious, shoot them at the speeds they are made for. Why some people can't grasp that is beyond me.
Yes, starting loads are light. Once in a while, too light. This is intentional. its why we call them "starting loads". You start very light, in order to find out if your gun is one of the rare ones at the bottom end of the bell curve. Once you test fire a few shots and know your gun isn't showing pressure signs at that level, you move up a bit.
You can build a cat sneeze load where the bullet hops out of the muzzle, walks to the target and engages it in mortal combat for several minutes before punching a hole through (rock DOES beat paper, here
) or you can build a screaming speed of heat load that blows through a dragon and asks "did I hit something??" but you WON'T do both with the same bullet.
Which doesn't seem to stop some people from trying....
