Jorge,
It is a mystery why some rifles love NPT's, other don't. Same with the TSX/TTSX; some like'em, some don't.
I've heard it postulated that the relatively open base on the NPT can spread somewhat, expanding to obdurate into a slightly oversized bore; better engagement of bullet with rifling, better accuracy.
Not sure if anyone really knows, but it has and is being observed. The Barnes are very uniform and can be extremely accurate. I find that with Cutting Edge copper bullets, similar results with GMX and E-Tips.
Do you find mono's to be more consistently accurate than NPT's, or said another way, do more rifles across the board perform better with mono's than NPT's?
I guess that's what makes Loony stuff so loony (and interesting)...
