RE: A cheap alterative to powerbelts?
BS - I have been using these for about a year, and took an elk with the 410 Great Plains with a sub base between it and 120 grains of T7 during the 2004 season. It worked very well - great penetration with some controlled expansion. My groups with this heavy recoiling load were running about 2" to 3" at 100 yards - looks like yours shoot a little better . . . .
