[QUOTE="codyadams, post: 2817392, member: 87243"] A big reason I find myself on this forum less and less. Super annoying. I have noticed crazy things with h1k in barrel wear (or lack there of) as well. Nearly 200 rounds down my 30 nosler, and the throat looks like this [ATTACH type="full" alt="Photo_20230417114635.jpg"]462232[/ATTACH][ATTACH type="full" alt="Photo_20230417114624.jpg"]462233[/ATTACH] My standard .338 Norma mag I had showed significant signs of fire cracking at under 100 rounds. The 30 nosler adg brass is about 102 grains H20 capacity, and I believe Peterson .338 NM is about 107, so 5 grains more but also a larger bore, so bore/capacity ratios should be similar, if not then the Norma having more favorable ratios for bore life. The difference? I ran N570 in my Norma. It's well known n570 burns hotter than H1000, but my observed difference in throat wear between the two is significant, if not surprising. I know barrels are wear items, and barrel life isn't a huge concern when working with large magnums, however if I can get 50% more barrel life from my fire breathing elk thumper, while keeping awesome consistency, temp stability, and loading forgiveness, with a powder I can find easier, and the only thing to give up is 50-100 fps max? Yup, I'll take it every day of the week. [/QUOTE]
