By center the reticle do you mean left to right? Bore sighting I did that and I'm dead centered. 4" low at 25 yds which I knew out of the gate was not good. The scope adjustments only allowed me to get to 2" low at 25 yds. A lever action 99 ain't easy to look down the bore. My guess is to shim the rear.
Experience hath shewn, that even under the best forms of government those entrusted with power have, in time, and by slow operations, perverted it into tyranny.
