I am going to use the lub a matic sizer by rcbs and the .455
sizing die but I can't find the number for the top punch, even at the rcbs sight, they give a million, punches how are you to know which one you need, there dosn't seem to be any refference. help

You're top punch should match the bullet nose profile. Check with the mold maker or RCBS to get the proper punch.

Pecos

rcbs.com, look at their products, moulds, click on the mould you are going to buy, listed right under the bullet picture there is the top punch number.

If your mould isn't listed there, try here: http://www.castpics.net/subsite/CurMolds/RCBSMolds.jpg


p.s. If the bullet you are looking at has a flat nose, see if you can buy a "blank" top punch in the correct diameter. A flat nose punch will work and can be made at home. I used a 1/4" diameter hitch pin from a hardware store for a while. It has to be modified to work, but is easily done with a hacksaw and bench grinder.

What bullet are you using. It's hard to help if you don't give this basic information! Give the part number and manufacturer, not just a basic description like round nose or semi-wadcutter.
