I use PPU heads for my 6.50 x 55 Swedish Mauser, again with Iron sights, I am happy to get them on a A4 sheet at 100 yards, so they do the job at a very reasonable price.

For my 223 I have always used top makes for cases, but have just purchased 100 PPU cases from Kranks, I will be reloading them this weekend and hopefully trying them next week, It will be interesting.
I will try to remember to put the results on site.
