I've used N133 for 69gr 223 loads, but you have plenty of less expensive powders that work just as good. VV isn't something I would normally choose for a 55gr FMJ plinking load.I've been considering adding these to my stores but not sure where they'll shine. I've read that the 2000-MR is great for both the 308 and 223. Also saw that N133 is one of the most popular powders in Europe for 55gr 223 loads. Anyone have first hand experience with these ? Your thoughts?
