years ago one of the local gun shop owners here claimed that the Jamming in the 740/742/4/7400 was caused by shooters not providing enough resistant to the recoil to allow the system to work. I think there may be a bit of truth to this . I bought beautiful model 4 from a friend he sold it to me with my full understanding that it constantly jammed.He called it the Remington jam-master. He probably weighed 165 lbs .I was a bit stouter, probably 60 lbs. stouter, and like to lean into the rifle. Anyhow I owned it about 5 yrs. In all the shooting I did it never jammed one time. I reloaded and used small base dies (30-06) I tried many loads , different bullet weights and powders . Not 1 jam . I got bored with it sold it to another guy he's had it probably 10 yrs. I ask him if it ever jammed on him , he said never.
Interesting. I wouldn't have guessed that had anything to do with it but then I have seen people jam pistols by limp wristing them so I guess it makes sense.
