Tried them in my rifle (Kimber Hunter) earlier this year; function was 100% no mechanical problems, but accuracy was terrible in the Kimber so they're no good for me. As usual with rimfires, all you can do is get some and test to see what is best. My posts do not rhyme all of the time; but sometimes they are in jest.
Sorry about the Dr. Suess bit, it just came to mind, and I could not resist and sometimes you'll find that humor is an entertaining twist...........
