Preliminary 22/29.5 SMc Ballistics and Accuracy Results
(Note that inconsistent neck tension and other problems related to case production almost certainly limit accuracy potential)

Preliminary 6.5mm/60 SMc Ballistics and Accuracy Results
(Note that inadequate neck tension, harmfully short case necks and excessive bullet-to-case runout probably tended to limit accuracy potential during this preliminary testing)

All loads use Norma 130-gr. Match (moly-plated by Norma under NECO license) seated at 2.72-inch OAL (base of bullet flush with internal neck-to-shoulder juncture), all testing at near 75-degrees F

(Several groups contained called fliers (excessive runout?), typically an additional shot fired and called shot omitted)
