The 69smk are very accurate in my Savage FP10 1/9".
My 4 .223s are all 1/9" and they eat up 50&55 gr bullets using w748. Those are my favorite weights in mine.
I just started to shoot the 69 to see how they would do....I am darn happy with those results. I am pushing them at about 2900fps, nothing fast, but cloverleafs at 100 make me smile, my best so far has been 3 shots in .333"
Im still working on loads using Varget, w748, blc2,h335.
