25g of varget with a 90 TGK at 2550 should not be a high pressure load I don't think. Hodgdon data puts an 88g berger at 2550 with 25g of varget at 38k psi. (Its their starting load) Not just that but nothing wrong with my brass after 4 firing exept some Shiney lines showing up because I was over sizing because my headspace was growing.
