whats the difference in these two bullets on stopping power on elk?

fail safes are almost like a barnes X bullet. except with that moly coating on it. both i think will do fine but i think the TBBC's would be my pick.the TBBC's are a bonded core bullet that has lead in it and would be like a partition but suited better for bigger game.

The bearclaw has a solid copper base that extends for about 1/2 the length of the bullet and the front 1/2 or so is a bonded lead core.In the case of the failsafe the front 1/2 or so of the bullet is solid copper with the rear half being a lead core surrounded by a steel cup.As far as performance the failsafes tend to penetrate more with less expansion while the bearclaws expand well but do not penetrate as much.The failsafe will almost always leave an exit hole that will make for easier tracking while the bearclaw will usually make a larger diameter wound which may cause a slightly quicker death.You really can't go wrong with either bullet.

stubblejumper got it right on all counts. Both are top quality and will do the job great and you wont recover either bullet in most cases. these are two of the best bullets out there just pick the one that shoots best and be happy.
