Looks like a great hunting bullet to me. the width of the flat nose which helps immensely on game, seems a perfect match for the bullet's diameter.

The crimping groove on the gas check seating step, is something I've not seen before. The idea/reason for it is a good one, though. The position of the groove will have to closely match the make of GC's you're using, of course.

I find when casting WW alloys, I like a completely frosted bullet - evenly all over. I get more precise bullet measurements and complete filling of all corners of the bullets this way. A narrow groove, as on the GC bullet's shank, might benefit from increasing your melt's temp, David.
