If someone is loading at or near maximum charges the difference could result in a KABOOM!
I was going thru some cases and noticed that there is about 3/16” difference in depth between F C (that’s F space C) and F-C (which is F dash C) head stamps. F C has a thicker web. I also found that W-W & F-C are the same depth.
To arrive at this startling information I used a highly scientific tool – a wood dowel tapered on one end so it would reach the web of the case.;)
Using this tool I also found that WINCHESTER brass is about half way between F C and F-C/W-W.
I tried to post this about noon today, but was unable to insert the JPG of this complicated tool.:killingpc
The top line is the depth of F-C/W-W. The middle line the depth of WINCHESTER. The bottom line is F C. I know about using water to determine case volume, but this is so graphic.:redneck: http://i286.photobucket.com/albums/ll81/BGOKK/Casegage.jpg (http://s286.photobucket.com/user/BGOKK/media/Casegage.jpg.html)
