It's a more durable chain then the non Duro chain, less stretching is the main feature it has plus better chip removal in big soft wood timber.
Don't confuse the round filed 72-73-75 LGX/LPX and JGX chisel chain being Duro Pro as they are not.
I agree, a wasted step is lost production when cutting.
The intention Oregon had when designing the wide kerf Duro Pro X chain was it's use in fiberous timber like redwood, cedar and hemlock. That was the market they were hoping to get.
That's a good deal alright, but I heard a lot of pro timber fallers didn't like the wide cutting Duro Pro X chain.... reason why Oregon discontinued it in the 3/8 pitch.
Yes I forgot to mention the "newer X Duro Pro" model , which was discontinued a few years ago. What Duro means is a heavier built like Stihl chain are, but with a slightly wider kerf.
So Willie you ended up with a chain close to Stihl:)
Willie, well you have a 100' roll of .325 chisel full skip .063 chain. A 100' roll of 3/8-.063 square ground chisel semi skip. Lastly two 100' rolls of 3/8- .063 square ground chisel full skip.[the X model being the Duro Pro style]
Really nice haul you have there.
The modern Stihl saws with the "Artic"heated carbs and Husqvarna's heated carbs would work fine there. But this advancement is only recent. Stihl introduced the electronic heated carb in 1992 on the 044 and 066. I field tested those first ones. The Druzhbas were a one of a kind though. Ran real...
I agree and after -45C the structure of metal is changed also. Very hard on the skidders and other other heavy equipment ,a machines $5000 walking beam is not worth breaking in that cold.
But having said that, there is little effect on the little chainsaw, bar and sawchain.
Built and tested...
Our best treelength pulpwood was our black spruce 4"-6" DBH , 40-45ft topped at 3 1/2". As thick as hair on a dogs back with a few limbs near the top. Lots and lots of smaller stuff. We have nice sized white spruce sawlogs also 24"- 36" DBH the very biggest being 5 ft at the butt.

We had to do what we had to do Burnham. In our cold logging wasn't so bad, when it was that cold it was always bright sunshine out, dry and you could dress and work comfortably. No limbing with the saw because they fell off by the time the skidder got them to the landing and the tops usually...
Magnus maybe you need more cold weather and frozen timber in Sweden.
In the winter of 1986 a Stihl engineer from the German factory named Yurgen Wolf came to visit us loggers in northern Manitoba Canada when it was about -35 -40 C windchill [minus- 40C and minus- 40F are the same] With our small...
I made a typo there I should have said LPX. I'm thinking old school. I think the reason LGX never caught on in Scandinavia is because Oregon makes the rebadged LPX for Husqvarna and Jonsered.

Stig you probably use the Oregon 73 LP chain and have tried the Stihl 35 RS chain. The 73LP does bore better then the 73 LGX or the Stihl 35RS because of the straight raker and ramp on the drive link. If you could get a hold of some Stihl Klassic chain with the straight front raker you may find...
Actually Stihl copied the "comfort" from Oregon's "anti vibe" about 7 yrs back. The heel of the cutters are a little lower then the toe making smoother cutting action. I can't tell any difference either.
"K" means Klassic [no safety bumps or links]
