Most likely test with a 24" barrel, that would account for reduced velocity with shorter tube( 40 - 60 fps in this velocity range per inch). First time I have seen 2 sets of data(other than 45 70), usually platform does not change data. Thinking higher pressure bolt gun loads will effect brass life.... Usually if it sounds to good to be true it is. We shall see.
