Hollow point

Dave, it may depend on the collet that your using. If your using 5C collets they they most likely vary and damage a little due to the way they work and are designed. The ER collets are a little different, but like I said I just popped a 1/2" collet in the chuck to see if it would tighten up on the 45 bullet and it did.
As far as getting your fixture lined up, I would probably use a dial indicator to dial in the spindle to the bullet, but thats just me, being an old tool maker doing things that way had become habit over the years.
Maybe one of these days I will dig though my inventory and see if I have some 400 gr bullets cast up and hollow point a few of then just to see how things work.
But all in all, for every problem you can think up there is often several different ways you can end up at the solution, not all of them will be the right path for everyone,but most will end up at the same place in the end. Just use what works best for you and all is good.
