I've probably had 10 over the years, and currently have two.

Maybe I've just been really lucky, but all of mine would shoot. I never messed with the forend, never handloaded. Just bought Hornady or Federal Premium ammo and went shooting. I can't even remember having to try multiple types of ammo or bullet weights. More often than not I shoot Hornady ammo in most of my guns, and it has generally produced 1" groups in any of the No. 1s I've owned.

I will add that most (maybe all) of the No. 1s I've had were either very early guns (first few years of production), or recent guns (last 10 years production). I think a lot of the No. 1's reputation for questionable accuracy came from the guns produced from the mid-70s to the mid-80s. But before or after that you are likely to get a gun with a decent barrel that will shoot well.
