Have you weighed a sample of [unmodified] bullets from the same Lot to determine the overall weight range? Determining the total weight range of 20-30 bullets ought to give you a pretty good idea of how the 0.5 gr you removed compares to normal bullet weight variance within the Lot.
I've encountered total weight variance within Lots of 185 to 200 gr 30 cal bullets of as much as 0.3 to 0.4 gr. Obviously, the 0.5 gr weight you removed is highly localized as compared to normal weight variance within a Lot of bullets. Nonetheless, if the 0.5 gr weight you removed falls within the normal weight variance of that Lot of bullets, you might want to remove a little more for your preliminary testing and proof-of concept experiments.
