I'm going have to reach deep into my bag of excuses for this target!
I marked the order of shots, sometimes this can help piece together what went wrong. The big thing that affected this target was the cross wind, it was mostly pretty mild but somewhere between posting the target and shooting the group it started gusting. Sitting my in shack with NO flags out I really wasn't aware of the gust until I walked down to get the target. The last 75 yards are more open and I could feel a couple strong gust from the right as I approached the target. Once to the target there were a couple of gust from the left but not as strong as those from the right. At least that's the way it was while I was at the target. Really very unsteady conditions, calm mostly then a wild gust or two from one way followed by one or two from the other.
So I figure shot 6 & 8 are when these gusts started.
#1 was from a clean, oiled barrel. I do run a 1 wet and 1 dry through before I start but it's only half moa high, could easily be the clean barrel.
#5 and 10 are low but I figure that's just the bottom of the group.
#2 did go a bit left but not very much really and could very easily have been just me.
Extreme spread ctc is 4 3/8" or about 2 moa, remember this is 219 yards. The core of 7 shots is 2 1/2" ctc and that's getting into the "pretty good" area. I just have to keep all ten inside that size.
Now I just have to figure out what to do to improve it some. Being this bullet isn't likely going to be used for long range I'm not going to work too hard with this 520 grain weight. I hope to use the 2-D elliptical that BACO is making for me for long range.
I am thinking I wouldn't mind using a 450 grain (1.260"long) version from this adjustable BACO mold for silhouette and gong matches to 600 yards. So I may switch to that weight and see what I can do there. I won't likely shoot a long range match until the end of September at Lodi.
So for a first load it's not too bad, but could be improved on.
