Final 3 groups plus the launch platform. As predicted the Hornady load grouped tightest and the Noblesport had the largest group and also the stiffest recoil akin to a 3'' shell. The recoil of the Hornady load though listed at a speedy 1600 fps was quite pleasant to shoot, almost as soft as the reduced recoil loads, that 1 missing pellet makes a real difference! The Nobelsport hung up on every round I tried to feed sometimes forcing me to drop a live round out the port to feed the next, that combined with the heavy recoil and the large donut pattern means that this round is a strict no-go for me, your milage may vary though. The PMC was a soft shooter and also quite cheap though neither pattern had any shot at the center. The Win. Surplus stuff didn't fare much better and at about .95 a shot (as I paid for it) isn't really a great deal but it does look cool as hell in a side saddle or buttcuff with its olive drab hull and blacked out brass.
The Fiocchi load was kind of odd, recoil was typical of 00 buck and exhibited very symetrical patterns as you see in the pic in the previous post. It was a cheap load also, the same as the PMC at .65 a shot but again put fairly little shot in the center.
The Rio Royal Buck suprised me with a largish yet decently even pattern. The length of the shells mean that I lost a round in capacity but it was the value pick of the bunch, this stuff is damn cheap and easy to find. Finally my favorite of the bunch, the Winchester Ranger Reduced Recoil did not produce the smallest group but both were very even and consistent in pattern density and easy on the shoulder too. Not the cheapest at about .75 a round but the cartidges seem well made and in my opinion offer good value. You get what you pay for and I am going to pay for some more Ranger
Now any of these loads (exept the Nobelsport for me) will get the job done for HD purposes so feel free to draw your own conclusions. And one other thing, mall ninjaness be damned! after burning the absoloute hell outta my hands and arms multiple times I am seriously considering a heatshield (there is a company that makes one to fit the heavy barreled 590A1).
