So I contacted Nosler and told them what I was experiencing. They asked me to send the box of bullets back to them from replacement. The bullets in the replacement box didn't display the problem. Their bearing surface diameter was more or less uniform like the other bullets in my reloading room I had tested. I don't remember what Nosler told me. Something about the bullet die may have been nearing the end of its useful life. I think the useful life had already been exceeded. I never shot any of the large-in-the-butt bullets for accuracy, so I can't say how they shot, or would have shot.
I did some very quick caliper measurements using a comparator, measuring essentially from the base of the bullet to the ogive, and I got some larger variations between bullets than the 210 bergers. I did not think enough to justify the awful groups I was getting. looking back I wish I had done more investigation of bullet dimensions, but I had an infant and a 1.5 year old at home and just didn't have the time... or the energy. I did call Nosler, and got the very opposite customer service experience. They basically said the problem was with the gun and not their fancy bullets. Good to hear you had a good experience because I certainly did not.
Again, I'm not saying you didn't get a bad box. Just saying that regardless of how good and accurate your rifle is, it is my opinion that there will be bullets that it just will not digest well at all. ABLRs or others.
I completely get what you are saying. That is why this whole thing bugs me. If they ever become available I'll try them again just to figure it out.
JMUPT, good feedback, thanks for the post. Good to hear they performed very well on game for you.
