Hello fellow riflemen, I am interested in learning more about the history of remington's semiauto rifles. My grandfather used to always hunt with a 742 in 30-06 and he was a really big fan of remington 742's and I have kind of caught the same bug lol. In western washington you encounter some relatively close shots and having the possibility to shoot off 5 shots in the time it would take to fire one from a bolt rifle is appealing to me. What are the major differences between the 740, the 742 and the 7400 rifles and were there any other semi auto rifles made by remington before these?, Are the modern day 7400's better than the 740 and 742's of the past?, if so how are they more reliable/accurate/durable or are they all basicly the same design with different names for clever marketing? thanks for any info :?: zach.
