[QUOTE="Wachsmann, post: 949592, member: 10429"] I just started load development on my 230's in the 300rum. Went out to the range only 200 yards and shot a 3 round 1.2 inch group. I was also working on load development for the 210's. They (210's) seem to be shooting the best about .065 to .070 off the lands. So I tried the 230's at the same distance. ( I used my hornady gauges to determine the distance to the lands). I got the 1.2 goup at .065 off the lands. .075 was opening up to 1.4 inch. My .055 was also futher apart. I was using the same charge of retumbo in all...88 grains. I'll be going back with more groups of 3 with at the .065 with higher powder charges to determing group and pressure. I was not showing any pressure signs out of the 88 grain load. I'm shooting a Remington sendero that has been braked. Just some info for those shooting factory senderos.... [/QUOTE]
