I just run a 5 day test with a little HW50's. This test wasn't about just the gun. I want to use this gun for a walk around woods gun, for everything from plinking to hunting. With HUNTING the main reason for this test. I also have noticed this one of 3 out of 7 rifles I own, that are always spot on the same POI whenever I call on them.
But this test considered first shot, 2 to 5 shots, cocked for 30 minuets and shot. I even wanted to know the what if scenario if I grabbed the wrong pellets. So AA 10.3 grain Heavy Field, JSB 7.4 grain RS Exact, and H&N 8.6 grain FTT. No exact shot count but excess of 50, maybe 70 pellets total. All with me leaning against the side of my house @ 22 yards. Prognoses was, if the gun can hit minuet of squirrel head at this range, with all pellets in all scenarios, I will have the confidence that everything else is on me, and the gun will not be the weak link.
Needles to say, with the best pellet, the 10.3 grain and 7'4 grain there is a difference of 220+ fps. with the AA HF running 620 fps, and the JSB RS @850 fps. I will likely choose the JSB. The extra weight would be nice, but the JSB I think will give me the cushion I need with my weaker range guestimation at various targets of opportunity. But both would be hard to choose from with the AA slightly less accurate, at least at 20 yards where I tested them.
The H&N FTT was about identical to the AA HF but since the speed was only about 100fps difference the better weight of the AA HF wins for hunting in my opinion over the FTT.
But here you have another spin on what matters for accuracy from a hunting standpoint. For group or score shooting, I would test and determine my winner in a much different fashion. Score accuracy as stated would be determined different from group shooting. And yes, I have guns as accurate shooting groups, but one seems more consistent with its POI for POI in various places on the same target.
