147 gr fmj 3.9 MIN -4.3MAX using WIN 231 Powder quote from winchester manual
win231 and hp38 are the same powder.
The barrels a friend of mine in Ontario gets are labelled "Olin 231" on one side and "Hogden HP38" on the other.HP38 has a slightly faster burning rate than 231. How can it be the same powder?![]()
147Gr Xtreme Plated, Win Small Pistol, 5.2Gr of HS-6 seated to 1.135 for 890FPS or a PF of 130.5
That day was really cold at around 0 degrees C so I want to chrony them in warmer weather and see the difference. The load is good, nice and accurate, clean burning and not alot of powder left over. I also had good success with 3.5Gr's of Titegroup seated to 1.140, I never got out the chronograph for that one.
