The most important number id the dia number which your barrel may like[/QUOTE

My ftp loves die 10, 2013 so I bought some die 10 2014 , these are definately NOT out of the same die , they are slightly longer and when you look inside the skirt they are completely different, not to mention a bit heavier, I only noticed all this when they shot 20fps slower, dunno if theyre a bit wider but when I tested a 4.53 they still shot faster so I, m none the wiser or convinced on the labelling of jsb, s , tbh I, m buying a sleeve a month to see if I can find a batch that shoots as good as the 2013,
10 , pellets of 1020014 are5.52
10, pellets of 10470013 are 5.43
Not being experienced in this lark yet I, d be interested to hear comments ]
Unless it's a typo, you have been using die 1 from 2014, and yes indeed die 10 from 2013.
