I would like some info on the:

.256 Bang Experimental
[color=#FF0000]May be a necked .30-06 Springfield[/color]
.280 Roosevelt
[color=#FF0000]Charles Ross’ first attempt at a .280, and was a .30-03 case with a semi-rim and necked down. Lost in obscurity because of the .280 Ross, which could be considered as a development of the Roosevelt[/color]
.280 Westley Richards
[color=#FF0000]Might be a necked down .425 WR, is so, very similar to the .284 Achilles wildcat[/color]
.298 Westley Richards Miniature Express
[color=#FF0000]A British Rook cartridge, possibly a design leading up to the .300 Sherwood, or maybe an experimental development on that case[/color]
