years ago I heard all the horror stories about the 742s and then the 7400s and the model 4. But my neighbor shot a 742 in 308 caliber for 18 years killing an average of 6 deer a year and never had one jam up or extraction problem. I bought a 7400 in 30/06 caliber and never had one minutes problem with it and I shot reloads. But I kept the reloads close to factory in trems of powder loading. The secret to any auto is clean it! Get a nylon chamber brush and keep it cleaned up! Make sure all the ammo is clean as well. I traded the 7400 when I though I was going to quit hunting (yeah right!) And it is still going strong and I bought it in the 70s. Clean it, oil it and take care of it and you will love it!
