FWIW to you reloaders.
According to the Oakdale Gun Club's newsletter, Pony Express Reloaders has been reopened under new owners as Pony Express Ammunition Manufacturers, Inc. I tried to go there earlier this summer, for the first time to look around, but they were closed due to the owner having some medical problems.
Pony Express Ammunition Manufacturers
608 E. County Road D and Edgerton
651-483-9406
I don't know much about them (that's why I went to see), but they are located on the frontage road on the south side of where 694 and 35E run together. Best way to get there is from I-694 to Hwy 61.
Your mission, should you decide to accept it, is to scout it out and report back.
