'06 and 308 work quite well sub sonic using cast bullets.

I use to load cast bullets for my Garnad and M1A for shooting at 50 ft indoor ranges at the NRA 50 Ft Small Bore targets for some good winter practice for my high power Matches (gets nippy in the winter in Alaska).

I used Unique back then but since they came out with Trail Boss I use it. 10 grns of TB in a 308 and 12 in a '06 works quite well with .311 cal 150 grn cast bullets at short range. Also cheap to shoot, no recoil and sub sonic. It also works in my TC w/30 Herrett and 30-30 barrels.
