.410 Frame Size Pin Spacing

[Dean Romig]

I've looked just a bit to find the pin spacing on the 000-Frame and didn't come up with an answer right away. Page 47 of the Serialization book shows all of the frame dimensions EXCEPT the 000-Frame.

By extrapolation, the spacing goes up or down by 1/16" with each successive frame size and where the 00-Frame pin spacing is 15/16" it would make sense that the 000-Frame spacing would be 14/16".... Right??

Anyone know for certain?

Thanks very much David. 14/16 translates (or converts) to .8750" so your measurement of .820" is even closer together than I would have thought subtracting 1/16" from the 00-Frame size.

Anyone else?

I found something online from a Shotgunworld.com discussion on frame sizes. The following excerpt was likely penned from our own researcher Dave Noreen in Sept. 2010:

"When the 28-gauge was introduced, they were built on the 20-gauge's 0-frame. Actually there is a good body of evidence that Parker Bros. took a bunch of 20-gauge guns that were languishing in inventory, and fitted them with 28-gauge barrels and moved some inventory. Later they added the 00-frame with a 15/16 inch firing pin spacing for a lighter weight 28-gauge then the early guns. Finally, circa 1926, they introduced the 000-frame with a 13/16 inch spacing for the .410-bore. "

That 13/16 works out to .812 inch.

Again, Thanks David, that sheds even more info on the topic. If it was indeed written by Dave Noreen there is no reason to doubt it.

TPS, page 527 I think, is a more complete reference for frame dimensions than The Serialization Book.
