I've had ejection issues with a couple 452's, they would extract the spent case OK but would just flip it straight up into the bottom of the scope then about half the time settle down in the ejection port and I would have to flip it out by hand, for this reason I haven't bought another 452, also I never was really in awe of the accuracy I got out of the three or four I tried. If your talkin a "for the money" rifle I guess they would be hard to beat, I do know several other brands that are better shooters but as with most stuff you get what you pay for, and rimfires are no exception.....................547.
