I've used 14g of Unique for years in the 375. I recently saw a guy use Trailboss at 16g in his so I gave it a try.i first shot it in my 1955 Model Supergrade with peep sight and it seemed very good.So 20210906_101400.jpg20210906_074011.jpgtoday I shot it in my scoped CZ Safari and results were quite nice.i think it will be my new standard plinker load.ill try it next with the Ideal 375167 plainbase.

I have a 190g Ranch Dog mold for 35 cal I use in my 358 Norma Magnum with Trail Boss. Its a dandy shooting load @ 1600 fps

Nothing wrong with that load. I used 2400 for most of my cast loads in 375 H&H.
