Got out to shoot today. I shot my Marlin 512 slugmaster. It is a bolt action shot gun, 21" rifled barrel with 1-28" twist. I have a 2X7 Nikon shotgun scope mounted on this gun. This shotgun is my best sabot shooter and my go-to stand deer hunting gun where I have to use shotgun slugs. I shot it off of a solid bench at my club, using a pedestal front rest and sandbag rear. I held pretty tight back and down on the gun to minimize jump. Weather was partly cloudy, about 45 degrees, light, breezy wind in the area, but our shotgun range is somewhat protected by a hillside on one side of the range and trees on the other. I don't think wind was a factor today.
I started off with some 2 3/4" Remington Copper solids, known good shooters in my Marlin. I shot two three-shot groups at 50 yards to check my zero from last year. Both groups were cloverleafs at that range about 2 1/2" high over the bull.
I then shot Copper solids at 100 yards. I put four shots into 1 7/8" with the fifth shot opening the group up to a total of 2 1/4". Dead center at 100 yards.
I have only 15 of the Hornady SST slugs available to shoot since I only bought three boxes. Cabela's sold out of them since I picked the last ones up. They didn't have many to begin with it seems.
Using the SST's, I shot three shots at 50 yards into one ragged hole. I then fired five more at 100 yards. My group at 100 yards measured 2 1/2" for the first four shots with the last shot making the group 3 1/4"
The SST's printed about 2" higher compared to the Copper Solid group, probably due to the higher velocity. Recoil was noticably more than the Copper solids but not uncomfortably so. I'm going to try the rest of the shells in my 870 Superslug next time I get out to shoot.
I'm going to hunt with the Copper Solids since they are readily available and shoot better than the SST's. Granted, the testing was pretty limited, but that's what happened today.
If anyone else shoots them at distance, please post. Interested in 100 yard groups, type of gun, conditions, etc.
