"The fact that various elements of the U.S. government are using ammo with Catalyst lends the new primer tremendous credibility."
Not really. We're talking about a body of persons which has made some of the most catastrophic and malignantly harmful decisions in history (the Tuskegee Syphilis experiments come immediately to mind). While it's easy to understand how lead can be harmful - the Romans stand in history as a glaring and often misunderstood example - the effects of bismuth and aluminum are not as well understood. For ref:
Klotz, Katrin et al. “The Health Effects of Aluminum Exposure.” Deutsches Arzteblatt international vol. 114,39 (2017): 653-659. doi:10.3238/arztebl.2017.0653
"The reference values for the internal aluminum load (<15 µg/L in urine, <5 µg/L in serum) are especially likely to be exceeded in persons with occupational exposure. The biological tolerance value for occupational exposure is 50 µg of aluminum per gram of creatinine in the urine. For aluminum welders and workers in the aluminum industry, declining performance in neuropsychological tests (attention, learning, memory) has been found only with aluminum concentrations exceeding 100 µg/g creatinine in the urine; manifest encephalopathy with dementia was not found. Elevated aluminum content has been found in the brains of persons with Alzheimer’s disease. It remains unclear whether this is a cause or an effect of the disease. There is conflicting evidence on carcinogenicity. The contention that the use of aluminum-containing antiperspirants promotes breast cancer is not supported by consistent scientific data."
Conclusion:
"The internal aluminum load is measured in terms of the concentration of aluminum in urine and blood. Keeping these concentrations below the tolerance values prevents the development of manifest and subclinical signs of aluminum toxicity. Large-scale epidemiologic studies of the relationship between aluminum-containing antiperspirants and the risk of breast cancer would be desirable."

"The possibility of bismuth encephalopathy needs to be considered in the differential diagnosis of possible Alzheimer's dementia."
This new technology holds some promise but let's not jump in with both feet cheering just yet. Do we wake up 30 years from now with a generation and a half of shooters - military veterans, police officers, hunters, recreational sport shooters - suffering severe brain atrophy or misdiagnosed with dementia from bismuth and aluminum exposure only to say, "Well, looks like the other side was right and firearms are just too dangerous for public use. Mr. and Mrs. America, turn them all in - it's for your own good and the health of others."
