Well I was shooting a Knight Vision, and I lost a nice buck using the Winchester 209 primer. Because I didn't read the label and had my head up my backside, I blew a nice deer. As it turns out not only is the Winchester 209 primer one of the weakest primers out there, the BP in the Knight Vision is a little longer then other BP. With those two elements working together, I was the looser!

Lately I have been paying attention to the manufacture's recommendations when they go through the trouble of putting it on their labels. Since switching over to the hotter primers in the Knight Vision, she has been humming along.
