Hi, Clarence.
I just did a search using the term "Wolf primers" ("Search" button on the green bar above) and found 110 threads on this exact question. I did the search because I remember answering this question a dozen times. In addition to my answer below, you'll get a lot more information by reading those threads.
Many of us have used tens of thousands of Wolf primers with no ill effect.
They appear to be good, and yield the same performance as any other.
They appear to be on par with Winchester in terms of sensitivity.
They offer a full line of magnum and standard types.
Give 'em a try.
