I love NPTs but couldn't get a warm fuzzy over the .22s
When they first came out our own JB ran a box through a Juenke Comparator, that measures concentricity. He divided the box into 3 subsequent piles...good, better, best.
Ive got a 'known entity' build in a .223 with a 1 in 10 Hart barrel that seems to digest everything, so I loaded and shot them.
They shot exactly how John sorted them:
Good: 1.25 inches
Better: 1.00 +- inches
Best : .75 inches.
If they were all that was available, I would embrace them, as I know terminal performance is good, and they definitely fit into the " hunting" accuracy mold....but lucky for us today there are so many other choices out there....
