I'm thinking its mainly the .454 bullets causing the slight sizing deviation......the main reason I posed the question was the fact that the bullets looked like they would barely compress 30 grains and I was unsure if compress meant to "mash" or merely (I believe) take up the excess/empty space that could result in excessive pressures upon detonation. Neither seating nor resizing a second time was difficult. The only noticable indicator on re-resizing was a little lube being "squished" out of the case mouth.
