I believe an intentional higher pressure can be a selected good thing. I feel many low pressure loads seem dirty, or may be more likely to be inconsistent. Anyway, I think cold weather hunting is a good place to consider a higher pressure book recipe.

That pressure spike was one of the things that came to mind when Doc Drew was running the Remington barrel blow up series. Seemingly insignificant swaps could feed a gun more than the shooter anticipated, by quite a bit.
