To be serious for a minute. Those Thors need to start in the bore for them to work. meaning the bore has to be big enough to get started. Then the bore will bend it in for a fit.
If the bore is too small to even get them started they just hit the edge of the bore and bullet. No way to push them down then. You could size them down just a bit to get them started and then the bore will fit them.
I had two packs and tried every one of them. No way to get them started.
So, to the OP. They'll work if your bore is big enough to get them started.
