I received the 300-grain Hornady cartridges fairly late in my testing of this caliber. Based on the positive results I had seen in their 240-grain offering, I had high hopes for this cartridge, though I was concerned that the heavier bullets might pose more of a creep problem. These fears were soon allayed, however, as the 300-grain bullets remained seated remarkably well through the entire battery of testing. Perhaps Hornady found a way to improve upon their crimp technique. Whatever the method, these cartridges simply performed fantastically – creep is minor enough that it can essentially be ignored, and the 300-grain expanders should be enough medicine to handle whatever situation that might arise. This is a winner!

    I’m looking for a black bear load. What grain, what brand is good. Going to Michigan in June to do some fishing in black bear country. Probably a hog danger also.

    Black bear aren’t particularly tough to kill; this Hornady cartridge is more than enough. Unless the hogs in Michigan are especially large, which I doubt, it’s also effective on them, though a hog’s vital organs are small and tougher to hit.
