I don't think it needs 3 grooves plus a crimp groove, but the length of the body really looks good. The nose doesn't appear overly long for a body style bullet & should be just fine as well. It will be slighlty flatter shooting, but of course, reduce the impact cavitation a bit.

It's a good looking bullet. Since you'll be paying the price for a 1-up mould - it might as well be as perfect as you can make it.
