I think the 1876 Winchester is much stronger than it gets credit for . My opinion has been formed from actually using one or actually several for a few decades . Yep I think you are right, most that parrot or repeat the old ( It’s a weak action ) say this because they have heard or read this and have no real life experiences that would prove this . Personally I have never seen the action of an 1876 Winchester fail due to over pressuring. I have no doubt it has a breaking point as every action does , but I doubt I will ever see it .,,,,DT
