The solution is effective but very slow - maybe you can improve upon it. I take a dime and place it between the pin of the tool and the 209 primer. The dime covers the primer and pushes it in undamaged.
YUP, a dime or, I use a fender washer, seats the new fangled primers just fine. Those old tools still work, but for me, work best with paper for roll crimping. Regards, Woody
