I never believed the bullet failed because it got my game with one shot. On tough game i will take penetration over expansion anytime. I have had a number of HP bullets fail to expand and this is the reason i use the hard cast 250 gr or 300 gr Keith bullets in my 44 Mag for just about all my hunting in my 629. I started this post to see what other people opinions would be. For my 500 Smith i load the 400 gr Sierra HP with Lil'Gun and will see how this works next hunting season.
