This is the first time that I have been able to shoot through the new Sightron and it was the first time other than the zero range that I have been able to find out if the loads that I am loading are grouping.
The Sightron is great! Optics spot on and the reticule really is to my liking. All the adjustments are positive and after testing the tracking, that is exactly as it should be and returns to POI after being wound all the way down then up again etc.
The first pic is getting on target, two shots then 3 at the spot marker. The boxes are 1 inch square and after putting the picture through the “On Target” software it gives a reading of 0.410 MOA.
Reasonably satisfied that everything was working, and working better than I dared hope, I shot a 5 shot group. It became difficult to see the original aiming spot, which I am sure affected the group size OF 0.628 moa.
I then had a chat with a couple of chaps making a lot of noise with a .300 as we let our barrels cool down. There was a 3mph wind from behind and the range temp was 15 deg, a lovely day to be on the range.
On returning to the rifle the barrel felt completely cool again and I wondered how that would affect the first shot. You can see it here as the one to the high right, not sure if that was the barrel or I pulled it, I certainly did not feel like I pulled it.
3 +1Overall it measures 1.107 MOA, shame as it would have been a lovely 3 hole group had it behaved.
Mindful that I will not be re loading any more rounds before the Phoenix F Class, and that every round shot is something else to be cleaned and prepared before next loading, I packed it up whilst the going was good.
Very happy with myself and the loads, I note that these cases had not had the flash hole de burred or primer pocket squared off with the depth tool. I wonder if I will see any noticeable change in group size when I start shooting the cases that have been “properly sorted”?
Load is 155 gn SMK with 49.5 Viht 550,
