The N320 of 10+ years ago was faster than the stuff they sell now, I’m wondering if the load data has been updated. That happened when clays production went from Australia to Canada.
I marked up a couple rounds before crimping with a .356 135gr bullet seated at “1.100 and you can see that the FCD sizer doesn’t touch the brass where the bullet sits.
I had the 4 inch mount on my 1050 and it was solid as a rock. As far as rigidity goes get the inline fab bin bracket, it makes a significant improvement in rigidity between the press and case feed mount.
Sorry no pics, I sold the gun a few months ago. I think I posted a pic of it, I’ll see if I can find it. I did change the angle so it was a bit forward.
I cut off the first hole of the ipsc Alex thumbrest then drilled and tapped a second hole straight to the optic mount. I only had to zero the gun once in two years.
