Winchester guarantees better sensitivity for more positive firing in all guns, carefully-controlled weights of primer mixtures, consistency in size and quality, precise measurements and tolerances for anvil heights, and stability in extremes of temperatures and humidity.

Thanks Brown
Brownells is one of about 4 online retailers I will shop at. This is because Brownells was as fair as I thought they should be during the pandemic shortages. I appreciate their honesty and integrity. I'm a customer for life now. There's about 7 or 8 other online retailers that I will never do business with again, ever! Most of you reading this know who im talking about.

Good primers
I have used Winchester large rifle primers for the past 30 years. Never a FTF, no blown primers, no problems at all. I have used other primers and have not been so lucky, FTF's were the main problem. But as of lately availability is a huge problem, as with all large rifle primers. I am fortunate that I have a good quantity on have to keep me shooting CMP and sniper matches. They are good primers and keep me medaling in my matches.

Some bad win. 41s out there
Why loading for 300 BLK out and other small rifle primer cartridges with fresh win. 41s last year had several FTFs. Yes they were seated correctly no the hammer springs are not worn out. This happened several times with several host all came out of the same 1000 brick. Nice hard primer strikes eject and out of curiosity let them sit for a bit reload them same results. Probably 5 or more every 100 with different cal. And different host 5 stars just cause availability
