My 7 SAUM shoots H-1000 with a 175 ELD-X at 3043 FPS at .5 gr under max. At 5 gr under max it matched book max velocity. Chrono ran my other guns where they usually run so I am assuming it's good. My barrel is 27" vs 24" in book so maybe 50 FPS there. Still it's very surprising to run that fast. Scale weighed charges on my other rigs that ran as expected. So right now I'm 200 FPS over book with 3" extra barrel length and no pressure signs (I have seen pressure and this one aint in it).
Same scale and chrono ran 7828 close to book.
My gun is built on a LA and COAL is 3.1 so I have some extra room but is it that much? This thing is beating RUM book speed with almost 30gr less powder.
What now lol? I am tempted to call it good and stay .5 under but I am also thinking its kinda scary to be pushing a SAUM to RUM speed, long COAL or not.
My experience says I'm OK but I have never had this problem, I usually struggle to get to book without issues.
