I asked on the other forum but didn't get much for replies. I got a good deal on an Ideal crimper with .429, .100 and .080 hexes. Then I got a die with .178, .128 and .068. Now all I really need is .255 and .213 to complete my needs. But there's all these other sizes out there, what are they for? I'm seeing .197, .178, .137, .100, .080, .068, .052, .042. What are these used for? Looks like I need either a MGS 7505-die-8X or RFA-4005-01. Best price I can find is ebay for less than $18 for the MGS one. I think I paid half that for the my crimper and die. There's some cheap looking ones out there too for $5. Also I find a lot of info on the dies and sizes, but not much info on what the different sizes are used for, or even instructions on exactly how and which to use. The normal stuff is easy, RG8, RG8X, RG58, 59 etc. The MGS site shows the normal stuff.
