I'm not sure if this is unusual or not. I just got a Magnetospeed (which I REALLY like) and decided to run a max-load work-up on my 22-250. Basically, an excuse to try my new toy. The rifle is a Cooper M54 Varminter. Powder used was Varget, pushing 50gr Sierra BlitzKings. I was really only shooting to look for pressure signs and test out the chrony, so I shot 3 foulers at 100 and went on to record: 36.0 ----3770 ft/sec ----No pressure signs 36.3 ----3793 ft/sec ----No pressure signs 36.6 ----3819 ft/sec ----Primer slightly flat 36.9 ----3834 ft/sec ----No pressure signs 37.2 ----3885 ft/sec ----Primer slightly flat 37.5 ----3930 ft/sec ----[BOOK MAX] Primer slightly flat 37.8 ----3980 ft/sec ----Primer is flat, very slight bolt stick The interesting thing was the shot distribution (picture below). The two shots in the black were 36.0 and 36.3. The only bad load was 37.2, which apparently shoots left Even at 100 yds, I was surprised at the lack of vertical stringing with a 200fps difference in velocity. Maybe this is normal for a speedy round like 22-250? I am certainly questioning the usefulness of my OCD powder trickling method. In any case, I am going to work up some rounds in the 36.6 to 37.2 range and see what I get when I stretch out a little. Historically I have been running 35.8 and it will shoot 1/2 MOA at 100. Maybe I can get a little more speed out of her. Groundhogs beware.
