UPDATE: (Tractor Supply) County Line .325 Full chisel chain.
Looking the chain over, it looks alot like the Stihl .325 23RS-C (no anti-kick links in the chain)
I tried it out today. It immediately stretched out. It was pretty loose after firing up the saw and throttling it up a few times just to get the oil flowing. Got it tightened back up, stayed tight after that. Definitely NOT a pre-stretched chain by any means. The teeth on it are alot wider than the regular .325 homeowner chains. I forgot to measure the width of the teeth, so i`ll do that tomorrow to see how much wider these full chisel teeth are compared to the standard oregon .325 chain`s. I noticed its not a round tooth design either, its a square cut tooth.
Going into the cut, i expected it to grab hard. It did not. Through the cut, it is fast, alot faster than the regular chains! Saw didn`t bog down nearly as much as i thought it would, given the size of the teeth are bigger. If these chains hold up decent, i`ll buy more of them. It cut clean and fast, and straight. The question remains, its a chyneeze chain, how long it lasts, will be the question. Also, when i re-sharpen it, that should tell me more about the chain as well.
