Not sure the analysis of "Not worth investing in the surge is worth it" is valid.
In 2018 there were 8,100,000,000 (8.1 billion) rounds of ammunition manufactured in the US.

Each round has a primer; and at an average retail price of 3.5 cents that translates to $283.5 Million dollars retail in primer value. Making primers for a corporation is fairly cheap (when capital machinery and plant costs are discounted). Assuming 25% in direct costs (mfg, pkg, labor, shipping) and a 25% mark up for distributor/retail operations; it still leaves $141.75 Million. If we see only a surge of 10% demand increase in 2019 & 2020; that means a ~$30 Million increase in primer cash flow to the manufacturers. On the surface; looks to me like there is a case for a more detailed analysis of the viability of expanding primer production by the Ammunition industry - using more actual numbers in the analysis.
By the way; anecdotally - it appears there is a much greater expansion of Ammunition (by inference primers) demand than 10% in 2019 and 2020.
