I checked my Nucleus and saw the shorter lead in on the lug that has the ejector slot cut, but as others mentioned that's per design.I could not find any burrs on the bolt head nor could I feel any click when running my bolt.
The action doesn't have the lightest bolt lift nor the most silky feel to it. Don't get me wrong - it's pretty darn slick and it beats every other rifle I have, it's just that it's a touch off from an Impact Precision or a Bighorn in terms of how smooth it is and the bolt lift is a fair bit heavier than something like a Curtis Axiom.
That being said, that's not why I bought this action. I bought this action because I like the shorter bolt lift (more clearance so I don't either bang my knuckle on the scope or risk the knob hitting my finger's knuckle when it's on the trigger under recoil like a Christensen does for me) and because it's a very robust action. By robust I mean that I've heard good things about how the Mausingfield actions just work regardless of the conditions. My experience with the Nucleus (since I fixed the issue with Timney triggers causing light primer strikes) has been exactly that, the rifle feels damn near identical regardless of whether it's had dust and dirt blown into it all afternoon or if I just cleaned and lubed it. I've never had a hard bolt lift, close, or travel because it's gotten gummed up. I don't have to worry about the ejector ever really breaking.
It's also pretty darn beefy, weighing in at 4 lbs (64 ounces) compared to the 28 ounces of a Bighorn, the 32 ounces of a Lone Peak, or even the 56 ounces of an Impact Precision. The weight is a plus to me, since I want a heavy rifle anyways.
