Over the past couple of years I have accumulated quite a few AR parts and pieces. Almost enough for a full rifle minus a barrel. I was window shopping on the White Oak web site recently and noticed they offered a few barrel kits. One of these is a heavy contour stainless steel barrel in .204 Ruger. I looked into the round but didn't find much. It exceeds 4,000fps with a 36gr bullet and there are very few powder options is what I read. I was wondering what your experiences have been in either shooting or reloading this cartridge. Any information is appreciated.
