The Best That Never Was 2 (Prototypes)

[StainlessSteelCynic]

I have a question for you regarding the Winchester AT rifle, how did you determine the magazine was 10 rounds?
In the video Ian says "apparently five rounds" and he mentioned single stacked but that box looks plenty big to hold more than five rounds. Without the internals for the magazine it's impossibe to see if it was designed for single or double stacked but it also appears wide enough to be double stacked.
However he does mention that the early versions of the cartridge were rimmed and the design was built around that rimmed cartridge so I'm wondering if there's some confusion on his part because of that?

The few websites I checked that had any details all state 10 round but aside from Historical Firearms site, none had any reference sources so I'm also wondering if you got access to better info that what's on the web? From what you wrote it sounds like you made inquiries at the Cody Museum?

Regardless of all that, thanks for bringing another obscure piece of kit to our attention
