I think the 'hang up' issue on the crimping as you are adjusting the die is due to the press going 'over center' which they are normally designed to do.
You may be feeling the ram pushing the case back into the crimp section of the die once again as the ram lifts slightly and then retreats as the handle is lowered back down to pull the round out of the die.
The heavier the crimp,,the more you will feel it on pulling the round back out of the die. All because the linkage going back over center will first push it back up to the max height before retreating back out of the die.
You can feel the same effect w/a FL sizer if you adj the shell holder on the ram to bottom out & touch the base of the FL die with the ram all the way up.
Then pulling the ram back down, at first there is a slightly more difficult to pull effort needed on the ram handle. This is the linkage going over center.
It first pushes the ram up,,and then it retreats and goes smoothly back down for you.
If you adj the shellholder/ram to be pressed too hard against the bottom of the FLSizer die with the ram at it's top position,,it can be near impossible to bring the ram back down because of that overcenter linkage movement that first pushes upward before moving abck downward.
re...Reloading Die Brands,,,I use and have about anything imaginable.
I use them all and they all work.
Somewhere around 60 different caliber sets and a lot of odd dies I use for forming brass and even making bullets
.
Some brands many likely have never heard of. Some others I have are those that many won't even consider as gifts let alone actually buying them. But they work just fine. A few home-made dies too.
They don't all have to have the same brand name on them either to load any certain caliber.
No die-snob here.
