I forgot to mention the group formed by Nos. 5,6 and 7. I had given up after #4 and allowed the barrel to cool. The vertical spread of 5,6 and 7 is obviously excellent and that gave me the heart to perform the McPherson method in full, on my rifle. This target was fired 2/1/2020. Nos. 1,2 and 3 measure under 11/2". All groups were of 3 shots with barrel cooling time in between. Perhaps #5 is a flier; the trigger lets off at 7 pounds. But the rot sets in with 8,9 and 10, which measures 31/2". The big red centre ring measures about 3"D. To easil find the bullet holes, the target was turned upside down after #6 and the next pic in the next post is included so you won't had to stand on your heads (wink).
