The rust issue puzzles me. I have owned rifles with barrels in the white. I have owned very old rifles with no bluing left on them and have never had a rust problem. The physics of rust or oxidation of steel are finite. Most if not all hard steels will rust at the same rate if exposed to identical conditions.
Most firearms purchased from smaller stores and dealers come from jobbers or middle men. Very large operations, ordering a hundred or more rifles can order direct from the manufacturer. When you buy a rifle from a smaller dealer, you don't know where the rifle was shipped from, how long it was in storage etc. You don't know if the rifle was cleaned and wiped prior to sale. In other words, you don't know a lot of things about the rifle.
I bought a new SPS Tactical in 308 a couple of weeks ago. I mounted a Nikon Monarch 5-20 on it and went to the range. I did my break in with inexpensive ammo, 40 rounds and then went through 40 rounds of quality ammo. During the breaking, I had some issues with a stiff bolt action. I also had a couple of feeding issues with the last couple of rounds. However, by the time I was done, I was shooting better than I have ever shot with any rifle. Mine came with the Hogue overmolded stock which is wonderful IMHO The trigger breaks cleanly with not creep at around 3#. It is not gritty at all.
Now consider, I cleaned the crap out of the rifle before I shot it and oiled the trigger assembly, (wet) as well.
I have owned Winchesters that were great and some that shot minute of barn. I have owned some beautiful Brownings that I wished would shoot as pretty as they looked but also owed a Browning in 375 H&H that would double as a varmint gun in the accuracy department.
If I bought a rifle that shot clover leafs at 100 yards, I would be a happy camper minor problems not withstanding.
