This may have been covered in an earlier post but here goes,
I load .30 carbine, .45 acp & 9 mm with my Lee Loader Classic kits, Redding #2 scale & Lyman 55 measure.
I complete each reloading step on all brass before moving to the next step. One day I'll get a real loading press but don't have room for it now in my limited garage work area. My " workbench" is based on 3 cheap kitchen cabinets & a piece of recycled counter top, pretty flimsy to be pounding on but good enough from scales, measures, loading blocks & the like.
I started using a 4 x 4 for a base for the loading steps that require pounding.
Then I noticed clearing the spent primers from under the shell base was a pain, if you don't get rid of them every 3rd or 4th case they clog the drop hole. So used a 3/4" wood paddle bit to counter sink a 1/4" deep recess in the top of my 4x4, then used a 3/8" bit to drill an angle hole down from the center of the recess out the side of the 4x4. Now the spent primers fall into a waiting bucket.
I added a second recess to hold the die steady while pounding the brass in to size it.
the shell base gets screwed down as shown so it doesn't bounce around while pounding the brass in & out of the sizing die.
i move the shell base to the blind recess for bullet seating, if left screwed down it effects the seating depth, not to mention my concern the screw head might fire the primer. Another hole for the depriming pin & priming pin as required.
the 4x4 is C clamped to my stool.
Not a very elegant solution but it's sturdy, keeps things in place & lets me use both hands with a lot less putting things down & picking up.
