Shot some today, all of the various loadings I tested shot well enough for plinking and coyotes out to several hundred yards, one of the loadings ended up with a .36" diameter 4 shot group. Time to load more of that one and try some faster loads. this is .223 with brand new nosler brass, loaded to various loads between 20 and 21.7gr loaded for a 0.037 inch jump (about the longest round I can get in the magazine without scraping the tips). I am also going to try loading up some with mixed headstamp once fired lake city brass, just to see how it works in unsorted brass (i.e. screwing around rounds)
all I can say is that from a cursory set of runs, it meters better, but appears a bit more sensitive (group size wise) than varget to small changes in the load. I'll be working through additional loadings to see what I find as far as a happy spot for load.
