Older Lyman 356" lube sizer die

Hi, I have just bought my first Lyman bullet sizer, and have the Lyman 356" and 357" lube/sizer dies,

Each lube/sizer die has two holes every (90 degrees) around it's sides 2-2-2-2



My question is, i just found a Lyman 356" sizer die that bought with some reloading dies years ago, I believe the sizer die is 20-30 years old, and in clean working condition.

It has holes on the sides that are staggered 4-3-4-3.



Why The change in the number of holes running down the sides, and do you know of any situations where this die would prove to work better.

wanna sell one?

There have been many configurations of hole arrangements over the years in Lyman dies as well as other manufacturers.

Since the .356" will be mainly used for shorter 9mm and .380 bullets, probably two will be sufficient.

When you get into the longer .30s like the Lyman 311467. it would probably be beneficial to have more lube holes.

Check the older Lyman lube dies carefully. Especially the ones with no O-ring on them as many have the stepped entry rather than the beveled enrty and this can cause problems in sizing.

A good machinist can correct both of these problems in about 5 minutes so the dies are still usable./beagle

Beagle, thanks, that makes sense.

What does this post have to do with bullet swaging?
