Bullet, Powder & Barrel Reviews
Click Picture for summary information on each one. Remember please, the results do not "prove" X powder is more accurate than "Y" powder in "your" gun. The purpose of the site is to create a "reference" to help you select a powder and a suitable charge "area" to get your desired results. What is more accurate for us, might not be for you. Accuracy aside, in a 24" barrel, it is logical to assume the velocity achieved with these loads will be at least comparable to a 24" barrel you use. Not exact, comparable. This gives you an idea of where to start to get your desired velocity result faster. I have a lot more powders than this, but powders such as Benchmark, or AA2230, etc, are just not that well suited for Valkyrie because Valkyrie likes the "slowest" end of the spectrum of powders that works in 5.56. Typically, powders that work well in 77 grain 5.56, are the medium, to faster burning powders in the Valkyrie range. CFE223 and Winchester 748 are perhaps the most "all around" balanced burn rate for this cartridge.
