Once I had the collet system made, it took me around 15 minutes to figure out the correct amount to take off the ogive to match up to the tip diameter. That number is a given that can be repeated quickly from set up to set up so that is not something that needs to be done every time I set up.
Once I got a few ran and figured out the process, I timed myself to see how long it would take just or my information from a labor stand point just in case I ever decided to offer these bullets for sale(still undecided on that).
On the conventional cup jackted bullets, After a bit of time I could pump out between 2 and 3 a minute. So your looking at around 120 to 180 per hour. I am sure it would get quicker with more time and I can see possibly pushing this up to around 4 per minute pretty easily with so time and practice.
The simple version of the process goes like this:
1. Release the 6 jaw chuck pressure, insert a bullet into the collet, tighten down the chuck.
2. Use my part off tool which is set up in the correct position to take the correct amount of the ogive off the bullet. Part off the nose of the bullet at 430 rpms
3. Take some 0000 steel wool and remove the small burr left on the bullet by the part off cutter while the lathe is spinning at same rpm.
4. Use a small center drill to make a starter hole in the face of the larger bullet meplat. Not deep, only around 25 thou is plenty. Same 430 rpm
5. Replace center drill with #40 carbide drill (not needed for lead) and drill 0.098" diameter hole 0.400" deep into the nose of the bullet. Same 430 rpm
6. Run part off tool across face of bullet again to remove any left over lead scraps from drilling process.
7. Turn off lathe, insert 22 cal bullet seater stem into chuck in tail rest. Insert aluminum tip onto hole in bullet and use the tail stock to press in the tip into the nose cavity of the bullet. Done and repeat for next bullet.
the Barnes bullets are harder to do and I need to order in some different tooling to make it easier to do them. The solid copper bullets really like to gaul up so if you push the drill to hard then stick pretty tight so you have to go slower with these by a little bit. The tips have a 0.101" diameter shank post and in the lead bullets, the 0.004" press fit is perfect, on the solid copper bullets, its to heavy so I need to order in a drill with a 0.100" diameter which should be perfect for the Barnes bullets. Other then that, its the same process.
Again, not hard at all, anyone with a lathe and a bit of time can do this easily. I am going to sit down and sometime and try to figure out a system that could be used for a drill press as there are more guys that have a drill press then have a metal lathe. I think it could be easily done, just have to figure out the clamping system on the bullet, other then that it would be easy.
In fact, it may be better on a drill press as far as pressing tips in as well.
