Hi Peter, yes, you are right about the paypal payments...but for the 3 stage I suggest you the four stage pass, as it's the best way for mechanic and esthetic result!
As example, yeasterday I tried my last prototype and I was be able to close perfectly my 12/70 Cheddite hull shotshells with 14mm of free hull space with 4 stage pass! Half Crimp - Conic Crimp - Special Third Stage - I2S Roller
Here we have to say that the other reloaders, has to use a special modified roller with just 1.00mm of touch height, when I obtain the same results with my special I2S Roller with 2.00mm of touch heigh...when all the other normal rollers has about 1.60mm touch height...
In the next few days I will try to put online some videos and some other pics...
Kind regards!
