No I am not going to try it in my Savage' s, since there is no need. I know of some who have shot T7 and have had breech plugs stuck tight. One individual sent me his Savage, that had been shot with T7, and the breech plug was stuck so tight I had to machine it out and install a new one. He was using Permatex copper Anti-Seize, that you use on automobile exhaust header bolts.
