I'm sorry you bought Beartooth bullets, as they don't have LbT lubricant, nor do I have any idea whether they are made in a LBT mould.
However, if they chamber alright, just use jacketed bullet starting load data and you will do fine, if the lube they are using is any good at all. If the fit is undersize or their lube junk, that worst that can happen is some leading which with come out with 3-4 jacketed bullets.
If I were certain you had bullets of my design, of a proper size for your gun, and lubed with LBT lubricant, you could use loads well over what jacketed manuals list, with complete safety and excellent accuracy.
