ArnietSome old data from Accurate Powder, which they no longer publish. So use with extreme caution:
For owners of a .460 Weatherby Magnum who wish a less potent practice load, I suggest
using the data developed with Accurate 5744 or 8700. This will permit varying the velocities
between that of a .45-70 and a .458 Winchester Magnum.

ArnietI should also say the 450 Rigby is very close to the 460 Bee without the belt.

xausaAA recommends filling the case up to the base of the bullet with 5744, weighing the amount, then multiplying the weight by .4 to arrive at a starting point for developing a reduced load. I have found this to work with a wide variety of calibers.
