I have a 7mm STW by robert gradous. I helped him build this rifle and i am a young hunter/shooter. I do know how to reload but i do not have a clue for what amount of powder or what is the best powder for my rifle. My rifle has a 28 inch Krieger barrel but i dont know the twist. I plan on using 160gr accubonds as they shoot best out of it, better than the 168gr bergers. It is flying about 3600fps and id like to stick around that number. What is the best powder to use for it? gun)
