I bought some G5 Montecs , shot one several times into a bag target and then sold them. Here's why.

I was testing heads for my hog hunt. I was shooting them all through a bag target and into a roll of foam.(old sleeping pad) All the new heads went through the bag target and through the foam the first shot and stuck in the ground. After the first shot, the G5 would not even go half way into the bag target. It was that dull after one hit in the ground. (NO, it didn't hit a rock) ALL of the other heads that I tried kept going through everything. The Muzzy 90 grain 4 blade and the Muzzy 3 blade 100 grain went through the bag and foam and into the ground more than 20 shots each without ever changing the blades.

NOW....to be fair, all you would shoot that Montec while out hunting would be once and then you could go home and re-sharpen it. I realise that, but those Muzzys are tough, (AND CHEAPER) so I stuck with them.
