When I bought the Waltz tool, I did a lot of 'water barrel' testing of different ammo (ie shooting into the top of a 200L open top drum full of water) to verify the performance of different hollow point designs (depth of HP and how open they were at the top). What I found was that there were brands of ammo the performed (expanded) well, but there were others that did little more than flatten the tip a bit.
I tested CCI SV with progressively deeper and wider HP openings, finally settling on a good compromise.
The Waltz tool gives you the best of all worlds in my opinion. CCI SV is a very good ammo accuracy wise, and well priced compared to others, but they don't make it in HP. With the tool you can then HP your own, to your own liking, with the projectile in the case, so your centralisation of the HP is accurately done. Takes me about an hour to HP 500 rounds, with a dye clean after every 100 rounds to clear the excess wax out of the head of the dye.
