I used them in my swede for a few years (and still do when I can be bothered to reload). Most of my stalking is woodland, so no great ranges generally but shot a few red deer on the hill and they worked fine for everything (few hundred deer in total). Accuracy was ok, about an inch, could prob have tightened it up a bit if I’d fiddled with seating depths etc.
Would happily use again. If I was shooting bigger deer at longer range would prob use something more frangible (yew tree, vertus etc).
