I know/recognise most calibres up to 243, but over that I start to get lost
ie I know that
223 = 5.56
308 =7.62 (7.62 x51???)
could there be a list of calibres in imperial with metric equivalents going up in size or could someone/anyone put up a list
ie
243 =
= 6.5x55
308 = 7.62
etc
thanks for any info
