Roger that! As I mentioned in my earlier post. Im running.50g for the first time because I couldn't get any light weight bars in .63! Ivey always ran .63 and as soon as I can find more 32" LW bars in .63 I'll be back to running it. .50g is way to light for my application. I swapped out a .50g chain today that is at about 50% cutter life. It was way way too stretched out. It was at about 90% when I threw a new wheel on the hub. My chains aren't pre maturely stretching or parting because of a worn sprocket. They are simply to light of chain fir what Im doing!Yeah .050 much too lite .058 perhaps , but .063 with the stock 660 is optimal & with a ported 660 necessary brother ! P.S. I'am running 48 " bar & .404 ripping chain on my ported milling 660 !
Bury 32" of bar on a hopped up 90cc in the wood for several hours a day six days a week and a .50g chain is simply going to be over stressed with too much tension! I've been at this game fir a long time. When it comes to this particular problem? I know what's up!
Ok, roger. Thanks for the heads up. Im no politician or a preacher, so those guys over there can have at it amongst them selves!
I can come up with way more interesting things to debate over than Politics or Religion! 
Im a huge fan of the .308! So much that I have four different rifles chambered in the cartridge! One of them being a Long Range PRC rifle.
Im about to have a fifth rifle in .308 too! 
I previously had a Remington 742 ADL . Bushmaster automatic chambered in .308 with a Redfield 3x9 & see under sights . Regret selling it , was a very effective rifle . Pretty well a all around gun if there ever was one !Im a huge fan of the .308! So much that I have four different rifles chambered in the cartridge! One of them being a Long Range PRC rifle.
Hope you both feel better soon.
Hope you guys feel better real soon Mustang! Sorry to hear about you missing out on hunting with your grand kids. You'll make it next time!
My old Pioneers have .404 & .068 guage as does my ms660 milling saw . 20 " , 24" & 48" all square ground full chisel .Roger that! As I mentioned in my earlier post.

Cut safe, stay sharp, and be aware!
Is .68g 1/2 inch pitch?
Im running Stihl chain. I've run Oregon quite a bit in the past, but prefer Stihl chain more. IMOP, Stihl grinds easier and the cutters are made with harder steel than Oregon chain.
That's Just my opinion.
Yes the Pioneers are the older 1/2 " pitch Carelton chain in .058 guage . The MS660 is running the standard Sten's or Oregon 3/8 " pitch in .068 ripping guage . All quite aggressive chains in the cut .
You'll burn your house down
.
I can imagine they are aggressive!

Tell me about them! Im not familiar with either.Stihl!

You should try the Oregon EXL and the husky x-cut.
No the ms660 is running the standard 3/8" pitch , its woods ported has lots of torgue . I have an auxiliary oiler of course , it does fine on my white & red oak applications . The chain grind stands up well , I run winter grade Syn. bar oil to ensure sufficient flow .
