Tin star is a replacement /equivalent to trail boss, it is designed for high fill, low velocity gallery loads (hence the name!)
You are taking a bullet that is too long for your rifling twist and velocity capability and running it as slow as you can. This combination was always going to give you stability issues which will lead to poor accuracy. Have you run it over a chrono?
Buy some 35/40 gr flat base bullets and a tub of lil gun and you will find it’s an accurate rifle
