Well on it's 42yd zero, my .25 FAC will put a mag of 12 in to a 1p size single hole, at my usual shooting rate of a shot every 10 seconds or so, I'm sure someone who did targets more seriously would get it smaller.
My .20 MFR does sub 5p single holes at 25yds, I might try it out longer but can't get 45m in my garden.
