Well, I shot some more groups.
First, the opinions. If there are rifles that shoot better than the shooter, this is another example. Also, this rifle shoots much better than the pellets we currently use. The advances in equipment and barrels will never end but until pellets catch up, scores are stuck. Maybe, this is a good thing as it will depend more on the shooter than the equipment, both indoors and outdoors.
The groups? 5 shot, 30 yards and remarkable when you consider there is nothing but air pushing these little pieces of lead.
4 groups, holy grail type, to say "one hole" is an understatement. No point measuring with calipers, only TDS would tell the tale.
21 groups, something up to .150 range.
Now, for me, this was frustrating. Once you shoot the little, bitty groups, everything else looks terrible and forces you to re-examine every aspect of your setup. Also, the choice of paper to print targets on is even more important when you want to do things like this. Bottom line, the chase continues.
