Another great picture and interesting timing I was plunging through an 18" Hickory today and got to thinking about this thread, after I was through.

I definitely have to change chains on my MS660 as soon as I've got my 066 back up and running and definitely before tackling Stumpkins or plunging posts.

I guess you'ld have to call my chains pro-kickback chains rather than anti-kickback, or perhaps semipro-kickback as they are low profile. But they are all ground ten degrees so you've got a real jack hammer if the back side of the bar gets too involved in the plunge. They'll also turn limbing into a real blood sport if you aren't paying attention.

Milton mentioned a "safety chain built for boring", who makes this chain? I'd thought the number one drawback of a safety chain was you couldn't plunge with them.
