Ramshot 'TAC' Powder

Anyone use Ramshot 'TAC' powder for reloading in the M1 Garand and M1A/M14 clones? TAC seems to fall in the acceptable range for use in gas guns based on burn rate charts, but not sure if it is or not for acceptable port pressure. Any information, or thoughts, would be appreciated. Ramshot webpage does not have any information and they don't even show load data using TAC in the .30-06, just .308 Win. Before I ask Ramshot the question, I thought someone might already know.

Spoke to Sierra Tech line 800 2238799 They list TAC in the i5th Edition .30-06 data That data is good to go for the M1 rifle .I hace some loaded but have not used them
