Ok, I was experimenting with my shockwaves that I was having problems grouping with this year. I found that on all of my sabots after the shot. The bottom of the sabot where it sits against the pellets, or powder gets burnt completely gone. I'm not sure if it is suppose to do that, or not. I mean it is completely a round hole the size of the shockwave bullet itself. Do you guys that shoot a 200 grain shockwave have any input on this? Just wondering if that could be the problem. Thanks for any info.
