Just a followup on the .650 round ball ammo, I took out the 590A1 on her maiden trip to the range today. I took half of the day off with the temp at 65* in the middle of winter in Maryland, this time two years ago on this date there was 3 feet of snow on the ground 
. The ammo did'nt shoot well from either gun leading me to think that the ammo was at fault. I ran some Winchester slugs thru both my 930 and my new baby for a baseline to compare by and to confirm that the guns where not the problem, the shot groupings from the ball ammo best summed up is for plinking only. For HD/SD use something else, this ammo packs one hell of a impact when it hits and keeps on going.
The accuracy out to 25 yrds is fair at best, very inconsistant shot groups, on some shots the wadding stayed attached to the round. The 930 had better groupings than the 590A1, and seemed to recoil harder than the 590A1. The Centurion shot better and had better grouping than the Nobelsport, looking at the two rounds they seem to have been separted at birth, both have the translucient casing, wadding, and crimping. At one full oz. and 1400fps this round will get tour attention when you pull the trigger it seemed to kick harder then the 1600fps Winchesters and penetrate deeper. At 69.99 for a full case of 250 and 15.99 for 50 this is ideal ammo for plinking and hording for SHTF. The grouping on the right are from the Nobelsport and the left are from the centurions. The top five on both targets came from the 590A1 and the lower shots are from the 930.
