With the hydraulics you can't tell much difference. When pulling the handle, you can feel them seat a little harder. I use reloaded Gun Clubs as throw aways when shooting my Fabarms Velocity and when I'm ready to load up a batch of those, I run them through a MEC super-sizer first. Makes them STOS.
Had a manual Spolar for the last couple years and yes you can tell a bit more resistance when ejecting the fully loaded top gun or gun clubs. Went to AA only but my wife bought me the hydraulic unit from Spolar for Xmas. Everything runs through it very smoothly now. Buy a hydraulic unit, you will love it. Lee
Keep checking the foot on your primer stand. If the set-screw in it comes loose it will slowly spin down, eventually causing your primers to be set so deep the firing pin will not reach some of them. I'm going to Loctite mine as soon as I am sure I have (again) gotten in in the best "average" position for the various hulls I reload.
