shot this 5 shot 100 yard group out of my sps earlier this afternoon. federal GMM brass, 168 grain SMK, 42.1 grains of Accurate 2460, remington 9.5 primer, 2.775" overall length. no crimp, and shot them as a single shot...did not load cartridges into the magazine.
the flyer was totally my fault, and i knew i whiffed it before i even looked. -matt 
meh. picture may or may not show. imageshack seems to be having issues tonight. |
nice

getting better. no flyers today. did note a little bit of pressure, manifest as the bolt binding and resulting in a little bit of rubbing on the case head when extracting. i am going to back off a couple of grains and see what happens. i managed to scrounge up a chrony today as well. 2723 fps averaged, with an extreme spread of about 70 fps over 5 shot groups. group measures 0.714".
i think i am about there. -matt
