I have a bit of Hornady Frontier 30-06 150gr FMJ from the 90s. Is this stuff garand safe? I cant seem to find much info on it( or any).

Although your brand isn't tested. Here are some graphs showing peak output firing various commercial loads as compared to M2 ball.
Contact Hornady direct for peak pressure to compare.
