[QUOTE="Cybra, post: 24231, member: 936"] I am one of those people cursed with few ambitions and delights in life; studying interior ballistics happens to be one of those aforementioned "fews". I've heard a lot of controversy over various case designs <of course>, and I'm minutely aware of some very interesting experiments ongoing as I type this. Now, stickly regarding conical shoulder configurations, as that's what I'm stuck with more-or-less for reasons of economy and practicality, I would utterly love to hear some comments. For example, I have heard that the best compromise to achieving what a hemizoidal <spelling??> shoulder will accomplish is a 30 degree shoulder. Humorously, though, I have also heard comments, supposedly from similar and, on occasion, same sources indicating that efficiency with a 45 degree shoulder is best, if the hemizoid cannot be used. I am familiar with the "well, it works for me" attitude--fair enough. But we all like to dream, and question, and I truly enjoy reading what others on this site have to say [thus far, it's the most educational single-source site I have come to.] [img]images/icons/cool.gif[/img] So here we go--concerning shoulder angles between 30 and 60 degrees, what are some thoughts? I'll list my intentions as this: take a 6PPC case, push the neck-shoulder junction back until a 45 degree angle is reached, leave the neck long <.3488", approx.>, and try some of Bounty Hunter's last link-listed tactics. I am familiar with that approach, and it sounds very mathmatical and swift. BUT--before we build this freakish thing, I'd like some consultation with the champs... [img]images/icons/wink.gif[/img] Anyone who feels inclined to share some tidbits, please do so--it will be very much appreciated, and should we bump into each other at an Irish Pub...well, first round's on me.
