I just happened to be out testing the Aguila SSS 60 gr this weekend also. I was shooting from a bench with a Marlin 39a and a lupold 3x9 scope. Distance was 100 yards. I shot over a Chrony and the MV averaged 898fps 6 feet from the muzzle. I had shot a group with some Winchester x-pert ammo which grouped into 3 inches, 6 inches below the point of aim on the same target.
The Aguilas put a 5 shot, 2 inch group, 16 inches below point of aim. They dropped 10 inches lower than the X-perts and had a better group by 1 inch. I would have shot another group but only had 5 rounds with me.
I am thinking of useing the Aguilas for the big bore part of Cowboy Silhouette this season. Last summer one of the guys I shoot with completed his NRA Hunter Bore Grand Slam by shooting 10 rams in a row with a ten inch Contender with a match chamber. The average volicity from that barrel is about 920fps.
