Just picked up a used ruger super redhawk 454 casull for 500 with an Adco red dot scope. I wasn't really looking for a scope but it came with one so why not. We shot it the same afternoon and WOW. Those 454 rounds are really something. We also had a 4" 44 mag smith which was like a pop gun after the casull. The scope worked well, we could hit clay pigeons on a bank at 50 yards in the off hand, which is good for me with a hand gun. The big ruger kicks but not like I thought it would. It was quite manageable. The shock wave that comes out of that thing is something else though. I'm looking forward to hunting with it. Can anyone tell me about the Adco scopes? This one seems kind of cheap. It has 0-11 on the dial for the red dot but shuts off on the 11 instead of the zero. Also, the knob that has the dial seemed loose so I took off the batt. cap and tightened a screw down lock ring and that seemed to help. The recoil could be eating up the scope. Any info. would be appreciated.
