For about $20 they offer many custom sized expanders for proper neck tension for us Boolit freaks!
I chose .312"-"316" (actually measured .3117" and .3158") and is perfect for my .314" sized 314299 boolits for my Enfield. The Lyman "31" M-die only measured .3097" and .314". After brass springback, the tension was too great. The expander is beautifully machined, and comes complete with a constriction locking nut. I was going to make one myself with my micro-lathe (Dewalt drill / Thanks for the tip Goodsteel!), but my time is worth more than $20. No more "second sizing" by my case necks! Lol
