Finally got out yesterday to try this out. Excellent results! The weather was cold with snow on the ground so I picked out some random targets at about 50 yards which were some nice fire blackened small cut off trees about 1.5" in diameter poking up out of the snow. I shot several shots at one and did not see any splintering or movement and thought I was missing it. I walked out to it and saw one trough in the snow behind the stump from the bullets. Looking at the small stump I saw several holes from he bullets. The stump was damp and the bullets were not moving fast enough to expand so they passed clean through like FMJ. I suspect these will do 1" or less on paper benchrested. I also attribute part of the accuracy to the Williams receiver sight I installed so when I go back to standard FP bullets I'll compare and see if the SP bullets were in actuality more accurate.
