It was also that you use pills from the .308, brass from the .223, and use the same bolt and mags from the .223. A person can get better performance from many different changes, but the ease of scaling/finding reloading supplies is unlikely to be apples to apples in these compare and contrast threads.
Brass and bullets are easy to find for the 300blk but not so much the powder. H110 and Lilgun is not exactly common.
