My shoulder has improved so yesterday I finally got out to have a crack at a fox. The foxes won.
I also decided to try some squib loads in my Marlin xs7 in 223. Normal re-loads for this rifle shoots about 0.7 MOA but are yet to be fully developed. The rifle seems to prefer loads at the light end as does my other Marlin.
All 4 shot groups were shot with a left to right gusty approx 20 kmh wind over 75 long paces. (conditions were better prior to setting up. ) They were shot off the very sloping bonnet of my I30. So far from ideal conditions and I would expect the groups would shrink a little given a better situation.
Cases were FLRS & loads were 6, 7, 8, 9 & 9.5 grains of AS 50-N under a Hornady 55gn SP #2265.
Three of the 9.5 gr loads were sticky to extract and the primers were beginning to crater. The group also blew out to about 2 ½ inches. (so group not shown)
Note: the grid lines on the targets are ½ inch. All loads shot low as expected.
Speed is not known. But previously found data for green dot suggests from 1550 fps to 2250 fps. Noise level was much lower than normal loads, as expected. All groups are about 1.5 MOA.
I will now load a few more between 7 & 9 grains in the hope of improving the load a little.
The loads that are horizontal would seem to be wind effected but one group (9gr) is more vertical and the wind was much the same for all groups so that has me tossed. Any suggestions?
