Sometimes when I cant get size 11's, I have had to use these other caps called No. 1075 by a German company called "Dynamit Nobel" (in a little red plastic container with a green sticker). They are the same size as an 11, but a little longer. Only trouble I have had with them, is the odd FTF because the first strike of the hammer seats them properly, the second strike makes 'em go bang
They got me out of trouble a couple of times tho
