2016: Federal 215 primers 31.79 per thousand (Superformance powder 20.89 per pound)

2020: Shooters world Tactical Rifle 8 pounds $150.99
My previous primer purchases date back to 2014. I stocked up. No one blinked an eye at orders for primers in the 10,000 each category.
For right now. this point in time: You need to purchase about 100 more than you need, except for SRP (223 stuff) and SPP(pistol stuff) buy what you think you can afford.
When the price rolls back, which will follow availabilities, stock up. Mine all still fire. Avoid the Wolf/Tula brand
