All groups are from 100 yards, I failed to mention in original post. Did some more shooting today didn't get to the 195 barnes but the other 3 I shot in front of 90 grains of tripple 7 loose FFG. With the T7 winchester 209 primers.
Very happy with the SST, wondering if the XTP would perform better with the high pressure sabot instead of the crush rib I'm currently using. 80 grains of powder the XTP shoots great, 90 it's not bad but spread out more than I'd like. Have 280g Bore Driver ELDX coming next week and 90 grain T7 with barnes 195 to try still. But it will be hard to beat that SST group.
Power Belt ELR is total garbage. So loose in the bore I can pull it back out with just a loading jag threads lightly engaged the plastic tip and comes right up. Will use to rough sight the 1x scope then I'm done with power belt
