I have been playing with some brown bears. They got VERY sharp VERY easily with the KME sharpening thingamajig. I shot one thru a 1x6 P/T that was backed with another 1x6(don't know what I was thinking.) Had to chisel it out and yet it still spun true. May give them a hog test soon and report.

to answer Michael a little late, I shot the bonehead 135's last year with a steel insert i got them around my 200g mark with a little grinding, they were great for me last year and very efficient on everything I shot

Thanks Boone    I'm looking closer at those Made In Michigan products again.
