I finally got a forster trimmer yesterday and trimed my first 50 cases. At 1.63 they are "rubbing". I got my trimmer set a little short on the first few, so I trimmed them all at 1.50-1.51. Is this any big deal? I went and shot and was O.K. with that. Just wondering if it was a thing I should avoid,as being criticle).. Thanks tootalloutdoors
