Remington 788 ?

...owned several 788's in the past, great shooters...had .222's,
.223 and 3 or 4 .243's, didn't have the problem you relate with any of them. The 788 is getting a little older now, you might want your 'smith to replace the ejector spring. Might just give it that extra little zip to clear scope knob. While he has the ejector and spring out, clean the mortise for the spring. I have seen one or two so compacted with dirt or rust that the spring could no longer compress. This is not meant to critisize your gun cleaning habits, the little hole for the ejector and spring are almost impossible to clean without removing the parts.
