I was given a lb of win wst powder. I'm wondering if I can use this in my 243 with cast bullets. If anyone has used it can you share a starting load. I see it's next to trail boss but I still can't figure a starting load. I was thinking about 4 to 4 1/2 grains. I would appreciate any help here. Thanks

Ed Harris has written a lot about such powders. Have a search of the forum.

I've found WST to be just a tudge, maybe, faster than Bullseye.  Basically, though in the 9mm and 38 SPL the measured pressures and velocities overlapped with the same charge.

Larry says WST is very near Bullseye, as do the charts.  We know that a lot of shooters use VERY small charges of Bullseye, or similar, for CB loads in big for bore calibers. I sometimes load 4 or 5 gr of TiteGroup in 223 for instance.

The powders are not identical, but there is nothing magical about different brands of powder with similar burning rates especially for very low pressure CB loads. Use very light loads and go for it.
