I witnessed remarkably little rifle, bullet, and load drama guiding- as in nearly none except bad, overly hot American handloads. Those rear their head as sticky bolts more often than you’d think, that’s user error however not the gun’s fault.
Have said it before, some didn’t do exactly what I wanted them to, but none utterly failed when properly placed. Had a couple scopes get knocked off zero, one cost a goat one year, same guy remedied that the next, but in contrast we had dozens go smoothly. I don’t doubt what Jon87’s saying, I just have questions like how close was it and what were the shot angles. I’ve done a lot of moose hunting with a lot of boring chamberings, never seen any bullets all but bounce off.
Have seen guns and bullets I dislike kill grizzlies, black bears, wolves, moose, goats, and others. Some did it slower than I’d have liked, but they still killed them. I complain consistently about the one trend I did notice, the stuff hitting animals around 2000fps and below was remarkably unimpressive and slow to act on average- none failed however. Had .300 Ultras show up routinely with incredibly fast impacts including Dogleg’s average range grizz, none of them failed either.
I heard these stories lots guiding from clients, but observed remarkably little of them in the bush in BC. I think it’s like a bad restaurant review, everyone hears about food poisoning nobody hears about a bland and mediocre dining experience that makes up the 99%.
