Your opinion on the optimal gauge/pitch for 14"/20"/25" bars

Stihl makes the chains at every thickness, .043, .050, .056 and .063.
I prefer using chains at .050 at my 50 to 80ccm saws, at smaller saws I use .043 - thats a "lot" of performance increase.

Maybe Philbert Will post his literature on Stihl Chain... I was reflecting on 3/8" chain but failed to mention that.

Ok, all my 3/8 chains - both regular and ripping chains are .050. Those are used on 70 to 80ccm saws.
But for the standard Logosol mill with a MS661, the Stihl ripping chain recommended is .050 - and its the best

That said, obviously you get less wear the thicker the stuff. And its stronger - obviously.

Huskys .325” .050” / .058”. (240se, 444sg, 353 )
Huskys 3/8” .050”/.058” (266 / 268/ 365/ 371, 372, 575/385)
Huskys 404” / .063” husky 2190/2101.

If you want the large radius nose in an Oregon hard nose bar you seem only able to get it in 0.063. That may figure into the optimal equation somehow.

Here is an old thread on the subject of 3/8 .050 vs .063 . The kerf of width of the cut I believe would be .013 wider on the .063 chain, https://www.arboristsite.com/threads/3-8-x-050-vs-3-8-x-063-chain.24774/

As Philbert stated Calipers and micrometers are your friend.
