I also like the Accubonds. They shoot very well in my rifle. I'm using Retumbo. I had better velocity using Magpro, but my ES's were way too high and my groups were inconsistant. Some time this summer I'm going to try H4831SC and some H1000 to see if I can get some better velocity. I get .3" to .4" 3 shot groups (factory rifle) @ 100yds but it's slow. MV = 3000fps.
