I will have a talk through video on this on OL’s YouTube and it’s gonna be a good point of reference to come. My 20” gas gun was giving 2695fps with the factory Hornady 88s and I shot the moose 3 times (which was a mistake, I only should have shot once, but hey).
First shot hit middle of a rib, tore off portion of near lung lobe and punched baseball-sized hole through middle of lungs, ending up in offside lung.
Second shot was running follow-up, hit in rear of hind quarter. After about an inch, put a racquetball sized wound channel about 10” to the femur and shattered it.
Third shot must have hit a twig and tumbled, impacted a couple inches from first shot, tore off lower near lobe of the lung, exited offside lung about size of a golf ball, and recovered bullet in off shoulder against scapula. Bullet did not expand, but appears to have keyholed into the moose. Still pretty impressive and would have exited a deer.
Three shots were fired in about 5.5 seconds and moose went down 40 seconds and 20ish yards after first shot.
