I was tempted for a while to buy a box and try 'em, then I saw the price on 'em.
In my humble opinion the 140s in .357 are too light for hunting anything larger than varmints. Outta a revolver they are a waste of money. There is no ballistic advantage to using them over any other major brand of jacketed bullet at revolver velocities, and even at the max rifle velocities recommended by Hornady(1650 fps), there is still only minimal advantage, if any at all. Most reviews I've read is, they are not as accurate as Hornady's XTP line, which are cheaper and can be had in weights that are more appropriate for hunting. For defensive situations, I doubt the expansion is gonna be much different than a standard 125 gr JHP. Add to this that cases need to be trimmed shorter than when used for other jacketed bullets, if one doesn't like them, you have brass that needs to be re trimmed to .38 special.
They sure are cute tho, with their little red nose.
