The issue that I had with four bags from one lot (200 bullets) of factory seconds, was that despite being told differently about second's quality, the bullets varied in weight by 1.2 grains for 210 gr .338 Partitions.
Normal distribution and weight variation of retail purchased 210 gr Partitions is about 0.5 grains per box with 96% grouping closely within 0.3 grains. Because of the large disparity of the seconds lots that I received, Nosler offered to and has replaced the 4 bags of seconds, (200) bullets. They have in fact replaced these bullets with factory first bullets and I am back in business with my favorite Partition bullet.
I was having group single flier issues trying to develop loads for the .340 Weatherby and .338 Federal rifles that I shoot this bullet in. Part of the problem was bullet variation and part was trigger creep issues with the Weatherby Mark V.
While I waited for the new bullets to arrive after the Nosler plant fire, I installed a Timney trigger in the Japanese Mark V having to fashion machine screw myself with a Dremel toll from local hardware metric screws that were too long and too large in head diameter. The old #2 Phillips head screws were soft MEM parts and the screws head phillips opening had been burred out by the former gun owner which that I had to drill out the soft metric screws and replace them. A Sears Easy Out kit had no effect on the soft heads of the Mark V Japanese screws. The new screws are real steel screws and are socket had cap screws that I shortened and refashioned to fit the rifle.
This trigger change, all by itself brought my 210 Nosler factory bullet groups down below one inch at 100 yards. No creep and clean break in the new trigger underlying this accuracy break through along with the new factory replacement bullets that Nosler was kind enough to send me.
