Well, I got to the range today and had a chance to run a few loads thru my XS-7 Carbine. I'm just starting the process, but so far there seems to be a few bullets that show promise. I'll have to try them with some different powders and see if they continue to give good results. This gun will be used mostly inside 200 yds so most of these trial loads would serve that purpose with no further effort, but I like to work towards the goal of getting good velocity and accuracy.
Here are some of the results. I'll post pictures when I get a chance.
150 grain Hornady SST, 46 grains of IMR4064, CCI 200, Military cases
2556 fps for an average over 9 shots
2177 fpe
1.13" average
best 3 shot group 1.08"
150 grain Remington Accutip, 40.5 grains IMR3031, CCI200, military cases
2523fps average over 9 shots
2121fpe
1.26" average
best 3 shot group .96"
170 grain Hornady RN, 43 grains IMR4064, CCI200, military cases
2412FPS over 9 shots
2197FPE
1.69" average
best 3 shot group 1.17"
These are just the first attempts at finding a good load for this gun. As the day went on, the gun seemed to start shooting better, so I have hopes of getting some loads that are even better .
