Why yes i agree, one should do what makes one comfortable, if possible.

Myself, i feel quite secure using W209 primer in my rifle. Those were what was available when i started shooting Blackhorn in that rifle, and mostly that is all i have ever used. Never once have i experienced a hang fire using that rifle, even when i shot it near 50 times without cleaning. After all them shots, the flame channel was so full of carbon, i couldn't run a 1/8" drill through it. A 1/16" drill was necessary to begin the process of cleaning the breech plug. One winter my rifle was left over night in the truck when the temperature dropped to -17 degrees. Next morning the rifle fired without delay, as it has every time when the trigger is pulled, and the firing pin strikes on them W209.

The second rifle i tried Blackhorn in would hang fire ever so often. Thankfully i understood it was the rifle/breech plug causing the issue, not the W209 primer. After the breech plug was 'fixed', that rifle never made a delay ever again. About that time is when i gave them STS primer a try, and they worked perfect in both rifles, except being shorter than the W209, they allowed more blow-by.

Today, i no longer 'test' the rifles, primers, powder, bullets, like i once did, however this October, when the trigger is pulled i 'know' the W209 primer will ignite the powder right now, and the bullet will be on the way, without delay. You know, i know, even though i really can't know, i just know.
