This is the current style

Name	Bullet	Length	Rim	Base	Neck	OAL
.50 Action Express	12.7 (.500)	32.64 (1.285)	13.06 (.514)	13.89 (.547)	13.72 (.540)	40.89 (1.610)
.50 Action Express	12.7 (.500)	32.64 (1.285)	13.06 (.514)	13.89 (.547)	13.72 (.540)	40.89 (1.610)
.50 GI		12.7 (.50)	12.19 (.480)	13.36 (.526)		31.01 (1.221)

I propose this:

Name	Case type	Bullet diameter	Neck diameter	Shoulder diameter	Base diameter	Rim diameter	Case length	Cartridge length
.470 Nitro Express^[1]	rimmed bottleneck	12.27 (.483)	12.7 (.500)	13.41 (.528)	14.53 (.572)	16.41 (.646)	82.55 (3.25)	98.04 (3.86)
.475 Nitro Express^[2]	rimmed straight	12.09 (.476)	12.75 (.502)	-	13.84 (.545)	15.77 (.621)	83.82 (3.30)	97.03 (3.82)
.50 Action Express	case type	12.7 (.500)	13.72 (.540)	13.89 (.547)	13.06 (.514)	32.64 (1.285)	40.89 (1.610)

Tell me the first is more intuitively useful... Or look at this:

Hi, just a short proposal: I'm not sooo experienced with those specifications but it would be a good idea to give the used measure for each column. Just like its nearly useless to me to read that some are mm and others are caliber/inch; how about stating in the table which is actually used for which? 78.48.0.63 (talk) 12:20, 12 February 2009 (UTC)Reply
