I had a Mod. 7400 carbine in 30.06 Spr. that I bought used. In a state of confusion, I guess, two years ago I sold it for what seemed then to be a decent enough profit. Frankly, I did not use it much. This particular rifle shot great groups and with proper cleaning, cycled just fine. I maybe put 150 rounds through it before selling. Never had a minute's trouble. The carbine length was great for hunting from a tree stand. I regret having sold it. Mine happened to "like" Federal Premium that had been loaded using the 180 gr. Nosler Partition bullet.
