I think it was probably a bit the other way around. Atlantic Ammunition had Chamberlin machines and loaded "Chamberlin" cartridges for sale in New York area.

Most of these cartridge loading companies were assemblers, getting their NPEs from Winchester, UMC or U.S. Peters Cartridge Co. and Western Cartridge Co. both grew from being assemblers into ammunition manufacturing companies. Many of these other regional assemblers fell by the wayside. Even into the 20th Century, out west here the reports from the big trap shoots show most shooters using shells loaded by local companies, Selby in California being the largest, but Piper & Taft and Hardy Hall in Seattle, Miller Bros. in Tacoma, Honeyman Hardware in Portland, Ware Bros. in Spokane, etc. were well represented.

It is easy to forget that this period was referred to as the industrial revolution.

It is interesting that Chamberlain and Tucker recognized that Parker guns were overbored and would perform better with larger diameter wads.

Wow great stuff thanks so much. Craig

yes good reading....charlie

WHOAAAAA. So much for primitive, hand-loading techniques. That contraption looks like a precursor to the MEC 9000H, sans the SAE30. I assume it was driven by that serpentine belt over to the right? Foot pedals or AC?? Had no clue reloading tools were that progressive so early on in the game. Very cool stuff (as always) Dave!

I'd like to tune that baby up and load a couple of thousand AA loads.
