I dont' work for RP. I have shot all types of brass brand wise. Though I have not shot quite that much last year, I average about 8000 rounds loaded and fired each year. Thats just in competition. Not in hunting ammo. Each brand comes with dinged necks at times. One factor is how much its annealed( IE how soft it actually is) the other is how long its tumbled and how much is in each tumbling batch. Though normally the time and amount are run at the same factor each time.

The misinformation I was speaking of is the notion that the discoloration you see on the neck/shoulder area and down into the body is acid wash. Thats the result of the metualurgy changing as a direct result of the annealing.

I shoot what brass works at a given time is why I know a bit about all this. Some of the most consistent brass I've ever found in 223 is RP nickel. Exacly what I did not expect to find. Yet in other calibers the RP sucks horribly. And there are all kinds of variations in between. Want to see something that'll really toast ya? Try buying a case of 223 from PMC since another match shooter had such good luck with them. I think the count was right at 5000 cases. Open the box and find that about half the flash holes are off center quite a bit. Almost to the edge of the pocket. A call to my buddy and he had the same batch but they were so accurate. I doubted him but loaded some up. Set 3 range records with that screwy looking brass. I've seen just about all. Including cases that came with a primer pocket but no flash hole.... And have seen that exact thing in factory ammo. Makes a mess when the primer pops and has no where to go except into the bolt face and firing pin hole....

What I speak of is not of a mere few hundred rounds of this or that here and there.

Does that make more sense maybe?
