Pick up a pound of 7828sc and a box of 162 gr Hornady match bthp bullets.
Id also try 168 gr Sierras or Bergers. Start at 74/75 gr and work up in half gr increments
till you see some pressure signs. H1000 will work also but 7828 gives better velocity.
Id shoot everything over a chronagraph if possible. You might see 3400 with the 162s in a 28" barrel.
Whats the twist, 9 ?
