[QUOTE="MudRunner2005, post: 1472307, member: 12995"] 65 grains of a fast-burning powder like N160 is a pretty stout load, as it is...Even with a 150 grain bullet. Sounds like you hit a pressure spike... Did the split look like this? [ATTACH=full]103809[/ATTACH] That's a picture of one of my 7mm STW brass that had a pressure spike, and it never showed any sign of pressure when shooting, so I cleaned them, and when I was drying them, I noticed several cases had this issue. I did some investigating and discovered that it had been a combination of crappy brass, work-hardened brass, and pressure spikes. Bought some new (better) brass, swapped to slower burning powders, and no more issues. [/QUOTE]
