Got a husky 346XP and it has a .325 chain .058 width for the bar . What is the big difference between the .058 and the .050 ? I understand it has to match the bar but the .325 and .058 is a "little bit" harder to find . I have only one chain with the saw , Am i better of going .325 and .050 before getting all the new stock in chain ? What is the input for chain for the 346XP. I normally have 3-5 chains per saw.
