RE: Propeller sizing worm can
I used 4895 but prefered 4350. The main reason was that at 55.4 grains the 25.06 casing was filled to the base of the bullet. Made for very consistent shot to shot. I had a .66" group at 200 yards, 10 shots. That was a good day.
I also had a custom 257 Ackley Improved that I really enjoyed shooting. It was a wildcat that took the 257 Roberts and fire formed it in the chamber. That too shot very well with 4350.
