Me neither, but now that I do most of it on progressives with 6 (Pro 6000) or 7 (Pro Chucker 7) stations, I add an "M" expander having the extra station, just before the powder drop, which means each case is given a square stable pocket for the bullet, flat based or boat tailed, into which my bullet feeder drops and sticks them square and true every time.....so then, when the progressive quickly swings to the seating station, the bullet is still exactly where I want it be.....so most any seater, seats straight and true. I tested just one bullet, because I wanted to see if the RCBS feeder required a bullet "stack" to push them in enough..........it didn't. One stuck just fine......not that common in bullet feed dies.
The video below shows one of several possible "M" die solutions, this one using RCBS's rifle tube feeder with it's included "M" die typically used in station 2. The video test below shows a single bullet drop in the already "M"die expanded "pocket". As you can see it's straight and true, and not about to tip on it's way to the seater, on any progressive merry-go-round....pretty darned sturdy....
Another....the original "M" idea......and yes of course a taper crimper to finish. "M" pockets taper crimp just fine with RCBS taper crimp dies too.
I never thought I'd use so many stations on a progressive for rifle......then came the "M" dies.
1-size/deprime; 2-"M" expand; 3-charge; 4-powder cop; 5-bullet feed; 6-seat (or seat/crimp) 7-crimp.
