Seriously interested in the M Die “like” expander plugs but not sure what size to buy for 44 magnum. I have two sizers. One that does .431 and one that does .4325. What size expander plug should I get for all of the loading?
For my Rossi 92 I size bullets to .433 and use the .434 x .430 expander plug. For other pistol loads that use .431 or .430 bullets I use the .433 x .429 plug. Seems to work well this way
