This is my first 6.5-284 lapua brass so I cant answer your question. I have Lapua brass in almost every rifle I own and haven't ever wore one out yet. I have only ten firings on most but they all look great.
My .260 AI lasted 12+ fireings with Lapua, including load developement on this brass, and have been running a 140 VLD at 3070 fps, so not a low pressure load. I have started culling brass due to primer pockets getting loose, down to about 50 left on firing 14. However, I now have peterson small rifle primer brass for my .260 to test out.
Lapua is good stuff, I went with peterson to buy American and have a small rifle primer in my .260
