I've seen the older style detectors they use have issues with bismuth because they're designed just for steel and are just a magnetometer. The Canadian guys took my word for mine being bismuth handloads without taking a shell apart but some might want to dismantle one shell. Could be the newer generation detectors, if there are any, have kept up with the influx of newer and different non tox shot types. I've considered carrying a small vial or ziploc with some bismuth shot or KTM or whatever to educate wardens who are not familiar with it.
