Pulled apart a couple boxes of 26 Nosler 129LRAB factory loads today, bought 4 boxes for a screaming deal just to tear down for the brass. I shot 5 rounds in my rifle just to see what they were like, velocity varied 94fps (3395 to 3489) and grouped about 2moa. The 129's in handloads never really shot that well in my 26, but no where near that bad.
Measured the powder charge in 20 rounds as I pulled them apart. 1.3gr variance! 84.4 to 85.7gr. That would explain the speeds.
Measured the BTO on the last 20 rounds, there was a .015" variance in length as well.
Anyone ever pull down some factory loads and find that kinda variance?
