OK, I’ll play.

Don’t know what good this will do anyone but….

I have found over the years that very small changes in one thing can make very large changes in the final results. Some casings and loadings are very forgiving, others are not. Note the velocity changes below (300 BlackOut-110gr-19grs of H110) with only 0.065 inch difference in OAL. Move on to the loads for .223/5.56s, totally different parameters between these loads.

The point is, what works for me in one weapon may very well not work in a similar weapon and whatever your weapon/s may be could be completely wrong. Start loading at a known safe point and slowly work your loading to where ‘it’ meets your needs.

All loading data is for reference and comparison only. My loads, made up from my components may or may not be safe in your weapon/s in the manner you put them together. Only loads from known and trusted sources.

.223/5.56 – different loads for different weapons and uses.
