OK, now we are in business.
Plug in a 0.340" nose, WW + 2% tin, a shank no longer than 0.100", a 0.080" long front band, and a 0.8 GtoB. The Beartooth photo is not very helpful, but I guessed at the front band and the GtoB by looking at the photo.
I'm guessing the Beartooth has a puny crimp groove -- so let's go with a 0.045" long crimp groove, since you are trying to duplicate the Beartooth, warts and all.
That'll get you on track with a lube groove. Fine tune the design to your taste.
Bear in mind that the program's OAL does not include the gas check thickness, typically 0.013".
Meplats are very difficult to measure, and most people tend to err on the large side, putting the calipers on the edge of the nose instead of on top of the nose. But, I am not going to try to second guess your measurements because I do not have a bullet in my hand.
Personally, I would go with a shorter nose, a smaller meplat, and straight wheelweight -- but then it wouldn't be a Beartooth design.
So much for the numbers on the Beartooth website. I've been down this road before.
