Got the Lyman mold - it casts 210 grains with my WW mix, checked and lubed. Loaded to to the crimp groove with an OAL of 1.832 it chambers fine in the new Handi .357 barrel. Just to be sure, I tried it in several .357 revolvers - it will chamber, but sticks out the front of the cylinder about 3/8 of an inch- so there is no chance of being used in a revolver. Because it seats so far out, there is actually more powder space in the case than with a 158 grain bullet. Anyway, loaded up a few to test with the Lyman manual TC contender section using Alliant 2400. Will try to post photo. In the lower right, there is a comparison with a 158 grain round nose flat point.
Thanks,
Dan
