Atlas,

I was going back through and reading some of what you had to say about what was happening and what others were suggesting.

I did think of something that might be affecting it. What about the spine of your shafts. I know I know, here me out for a second. You might be punching bullets when everthing is perfect which may happen 99% of the time, with the mechs and field points you may never see it. But with those muzzys or any other bigger head you just may. Its just a thought, something that might have been overlooked!
