Speaking from experience on this subject, having shot several bears in the past decade with a Winchester .45-70 lever action rifle... I've never had a problem dropping one with that gun.
These things can only happen in the mind of out resident NUT-CASE, the TARD.andy said:"with one shot". Not without a brain or spiine hit it doesn't and a 223 would suffice with those. I got news, 12 ga slugs don't always stop adrenalized, 100 lb DEER, and a 45-70 is 405 grs, 1500 fps. 12 ga is 440grs, 1400 fps, with over 3x the "frontal area" of the .45 bullet. so those who "think" 45-70 is so great are simply IGNORANT of the FACTS. Ditto those who "think" .45 ball is such a great "manstopper". They've been reading too many bs stories, that's all.
