I tend to load large batches of hunting ammo and may not shoot it all in a year or two. After reading about how the dissimilar metals react over time and causing pressure/velocity spikes I have been thinking about how to minimize it. I do try to leave a bit of imperial sizing wax in the necks and have quit wet tumbling my brass to leave a bit of carbon. I believe I have seen the cold weld issue on my 223 ai fireform loads but usually chalked it up to fireforming. I am thinking about loading a few batches of hunting ammo for some rifles and they need new loads worked up as well so I figured now would be the best time to experiment with HBN if it has benefits. I like the claims of better cold bore consistency but really I am just looking to improve the shelf life of my reloads. The other question I have is am I overthinking this?
