I have shot those (not sure if same brand but same wait and looked the same) before. Just wanted to see how they functioned in my Coonan. They worked fine. There was not alot of capacity so they where pretty slow but they did stabilize.
Shot placement is everything! I would rather take a round of 50BMG to the foot than a 22short to the base of the skull.
all 26 of my guns are 45/70 govt, 357 mag, 22 or 12 ga... I believe in keeping it simple. Wish my wife did as well...
