MS880 Mod's For Milling...

[Lightning Performance]

Its hard to believe but there's not much difference between the kerf generated by 404 v 3/8. The main reason I use 3/8 as it helps minimise the number of different rolls of chain I keep on hand to cover my saws. I've used 3/8 on my 076 and 880 without any troubles (one very undramatic breakage in 15 years) and doubt you will ever mill anything as hard as I do.

Many don't realize a fresh loop of RS 375 063 has a wider kerf than a worn loop of 404 semi chisel chain.

3/8 lo pro is a game changer, don't be afraid to tighten it up properly.
Panther milling chain works exceptionally well, it's lighter than the Stihl chain but I've milled holm oak with both and the panther is well worth the small premium.
