Lyman M case mouth expander plugs:

Post by Stoneke: » Mon Oct 09, 2017 9:42 am

Lyman doesn't seem to offer their rifle expander plugs for their M dies in sizes .451 to .453. They do, however, offer this size in their pistol plugs for the 45 ACP cartridge. My sense is that these might for suit my needs for paper patched loads, patched to bore diameter of .450. I am assuming that the plug threads are the same between rifle and pistol offerings. Anyone with more experience want to comment?

After talking to Lyman, my only option is to buy the rifle expander plug and have them turned to the correct diameter. The pistol expanders are of a different design. Baco also doesn't offer any plug that I see in the .450 - .453 range.

Go with one of the custom expander plugs from BACO. I use one of them that is tapered from 451 to .453 for the 45 caliber paper patch loads.Going with the bit extra diameter will allow for the brass to spring back after you run the expander in the case mouth.
You can also get the M die bodies from BACO.

Buy the expander plugs from Track of the Wolf and turn them to size with a lathe or drill press

The M die is fine for the smaller calibers. I went to the Lyman M-2 die body that has a wider opening for the bottle necked cases and the .50 caliber. The M-2 will work fine using any size expander plugs.
