Hi,
Nice rifle, I do like my Crowns.
OK, I think you have a new power wheel, which is like the new wheel on the Impact M3 - I have not seen a new Crown power wheel yet, I think it may be marked that way rather than the A,B,C D type. Simpler 1 - 23 - I am guessing they use the dot's in-between because it creates a space and maybe too jumbled if it was all numbers. So I think you have a new function that just has not made it into the manual yet. Nice. ?
Scope wise, the MTC King Cobra, has quite a bulbous section in the middle....have you tried mounting the scope so the front part of the tube is over the Mag, rather than the section in the middle where all the turrets join up. I know exactly what you mean and I have found on some scopes the joint in the middle can get in the way, so maybe a small experiment on placement is what I normally do.
Mag wise with the last pellet, I have never heard that one before. I do wonder if the magazine is a little loose on the spring, and not gripping the last pellet correctly.
Noise's from inside, the Wildcat has a floating hammer, so yes you hear that moving....I wish I could be 100% but have not seen a new Crown yet, so it maybe a floating hammer. I dont know on that one - remote diagnosis is never easy. ?
To be 100% sure, maybe ask the RFD that sold the rifle, they should know....or be able to answer questions for you.
Hope I helped in some way with some of it.
