Anyone here play with one? Have a set of dies? I have R-2 Lovell dies, but they won't work for sizing or seating the Maximum Lovell. Back to square one...

In the same vein, has anyone successfully substituted H-322 powder for 4198 in a small case designed to be most efficient with 4198? Again, for the Max Lovell. I'm out of 4198, but have scads of H-322.
