First, I would like to point out that because the breech is so small in SP and related markers, there's really no reason people should have stack clipping issues. This is evidenced time and time again in threads for people who use Pooty bolts, they point out they've never really had a problem with stock but got the Pooty bolt anyway.
At any rate, he's correct in one thing - the Pooty bolt keeps the next ball in the stack indexed better while the gun is at rest - by a whopping hundredth and a quarter. That's right, .0126".
0.0263 - 0.0137 = .0126"
What's worse though is what he's sacrificed for this - keeping the next ball in the stack at a relatively consistent height. You can see in the next two pictures that the Pooty bolt allows the next ball in the stack to fall behind the ball in the breech - creating clipping on the bolt itself. The detents should be keeping the ball on the bolt face at this point, so the balls should be in the correct position.
The eigen (and other open-faced bolts) will have no such problems:
That means it's actually worse
at keeping the next ball indexed during the firing cycle by .0417 - .0258 = .0159".
This actually falls right in line with the video on the previous page - where there was clearly ball breakage with the Pooty core and no such issue with the NOX bolt.
Pooty, the next time you want to pretend your products provide a performance gain, you should either make sure you're not selling bull**** hype or at least that I'm not posting in the thread. I will freely admit the eigen is not perfect, there are actually a few parts of the design that are not ideal. Feel free to critique it on those. But don't make up fake criticism. It makes you look bad, and since this is the Shocker forum most of us are experienced enough to know the difference.
