what I have found with the partition either a rifle loves it or hates it the ones that love it shoot lights out the ones that hate it shoot the 1 to 2 inches you spoke ofAnother question on Nosler Partitions. When I first started hunting I grabbed two boxes of 140 grain partitions loaded by Federal. I could never get them to group better than 1.5 to 2 inches at 100. Since I started reloading I checked the coal on the 120 grain ttsx that were shooting sub moa and found that it was right at 2.750. I decided to check the noslers yesterday and found that the coal was 2.745. I wonder if they are two far off the lands and if seating them at say 2.750 or longer (closer to the lands, even though i don't at this time know exactly where the lands are) would help with accuracy. Thanks again everyone.
