I think I figured it out, if someone can confirm.
On the Hodgdon Burn Rate Chart it goes
3. TITEWAD
5. Hodgdon Clays
8 TiteGroup
12 Hodgdon (Clays) International
16 AA #2
21 Hodgdon (Clays) Universal
Jeff Maass's warning is about the 5th fastest "Clays", not all "Clays"???
I went to the range and alot of them are using Hodgdon International, one said he does
180 gr, OAL 1.2, 4.6 - 4.8 g for Jacketed rounds
for cast lead, .5 less.
sorry for the trouble.
