These 1:28 twist barrels seem like they like long bullets with heavy charges or shorter and lighter bullets with moderate charges of 80 grains or so.
That is what I experienced with my Omega. This barrel is a flinter so it rules out T7 on it's own. We'll see once the white stuff gets down to a manageable level. Then I will only have to fight the skeeters, blackflies and deerflies.[:@]
