[QUOTE="Trickymissfit, post: 589331, member: 25383"] The one real problem a Forster has is that with it's high leverage ratios it's easy to collapse a case in the die if it's not setup correctly. You always start out with the die set high (or long), and work your way down. I once stuck a 41 mag case in an RCBS die that was so bad that I had to put the die in an arbr press to get the case out. It looked like an accordian! But on the otherhand the samething would have happened with anyother press. It did tear the rim off the case as you did. I found the problem was the die being set too low and that case lube failed to do it's job. But on the otherhand the jaws did their job as they didn't let go. I now set my jaws up kinda loose, and if it happened again, I could get the case out much easier. Issues like this are simply part of the learning curve. The Forster floating jaw system does not aign the case, nor does it retain the case during a sizing operation. It only retrieves the case from the die. The bolster plater is what locates the case head (under the jaws). This takes any machined error in the shell holder out of the equation. Does the case move much during the sizing operation? Not as much as everybody here thinks it will, but it does move a little as the die slides over the case being sized. I do not use the Forster lock rings like most guys do. I like the steel Lyman rings as they are a few thousandths narrower, thus allowing the die to also align itself. It's not perfect, but in my mind the Forster ring is so tight in the groove that any machined error is added into the alignment. I also do a procedure to square up the ring with the threads under pressure. Does it help a lot? I doubt it, but it gives me peace of mind. The system is not perfect for sure, but at least it's a start in the right direction. I personally would like to have seen a hard insert where the case head contacts the bolster plate. I also would like to see them make a press with a half inch longer stroke (all they have to do is make different links and longer guide rods.). Another thing the might think about doing is going to a larger die body with a press design that supports this.

A 1.125" x 12TPI would be perfect, or the same 1.25" thread that the big calibers use Lastly if your near me, I'll be glad to allow you to try my press out anytime. gary [/QUOTE]
