Ok so here it is . I have loaded only for the .223 in a bolt rifle and would be the first to admit there must be more varying load data for this calibre than any other BY FAR . Enough to make you cross eyed and take double doses of Advil. I understand the the seperation of the 5.56 and .223, barrel twist rates and bullet weights they stabilize and so on, but what I need to have explained to me I guess are the guidlines for load pressures that determine a load for a given lets say an AR with a 1 in 8 twist and 20 inch barrel vs. a bolt rifle of the same configuration. I am speculating to get the AR to cycle the bolt a load would be increased slighly to equal the chamber pressure in a bolt rifle with a given powder and end up with an equal muzzle velocity ? I am asking this if anyone has seen this to be a factor of any real consiquence in load developement between the Black Rifles and bolt guns or will loads that are within pressure limits tend to perform fairly equal ( as a rule ) in both weapons ? Looking for personal expierience feedback here as I understand no 2 weapons will perform exactly alike due to a host of varaiances that can be present . There are literally thousands of load recipies available from powder manufauctures and on line these days , dozens of powders and even more bullets to pick from and Black rifle data seems to have gained the majority as of late. Understanding this should help to narrow down a persons initial powder selection and starting charge weights ( somewhat ) on a new load developement. In case you havent guessed this is what I am gearing up for once again and dont have an abundance of cash to just "buy em all an shoot em up". Look forward to your input here folks !
