I have now been to range twice with the new 527 Varmint in 204 Ruger.
42 rounds the first trip
40 rounds the second
Here is picture of round # 16 - 20 (5 shot group for those weak in math)

Yesterday, 4 of the 8 5 shot groups were touching. I was testing 40 grn'ers since I have read some will shoot some wont.
Well, with 27gn of 8208, I had four in a single, enlarged hole, and then was watching a bleep big ol wood borer type bee at my hand, when I foolishly pulled the trigger, fouling that group up.
I do not like zealots, and do not want to turn in to one, but I am utterly mystified why EVERYONE does not get this rifle if they want to shoot at paper. Everyone!
