As long as you drop back and work up to be sure you're not over pressure, I don't believe you'll notice a huge difference. I know guys who swear by one brand other the other. I'm using Fed215s, but the reason I'm using them is that's what I got the best deal on a number of years ago, and I bought in bulk. I also have CCI, Winchester, and Remington primers on my shelf, both magnum and standard, and use them with no issues in other chamberings.
