That load is a bit hotter than what I shot, and I thought mine was flat shooting. 9.8 gr AA7, 1.165”, 11 lb spring, with the Berry hollow base round nose (thick plate) 115gr.
Damn... this was one of the main reasons I got rid of my Czechmate... I was so annoyed by the mags.
I'll have to keep my eye open for another, or see what the new Czechmate 2 has.
Just curious if you got your dot bounce figured out? What OAL are you loading to?
I have a pretty good recipe for the Czechmate with Accurate No 7... PM me if you are interested.
I've done a lot of 300 blackout subs (200-220gr bullets)... and they get a bit wobbly if loading too fast. Good thing you can slow it down, which slows the wobble down.
I have never had an issue with large primers, but I'm using the old school primer stack and shuttle on my evo-autodive.
Need to be realistic and not expect to load at 2000+ RPH.
Get a hold of Wayna at MA... he's usually quick to respond via email.

How much do you need to trim off each case? Worst case
I would be a bit skeptical that you are going to get some brass shavings in the case... probably not the end of the world though.
Might want to add a Lyman M-die after the trimming to pre-flare the brass.
I trust M7 has done their homework. I ordered one and will give you some feedback once it arrives. I can't wait to try it on large primers.
I also don't reload for a living, so if it's down for a bit.... it's not the end of the world for me.
