[QUOTE="FEENIX, post: 2593712, member: 14204"] Since this post, I now have .257 WBY (1:7" 5R) primarily built to propel the BJ 131s, Berger 133s/135s, and the Black Hole 145s. [ATTACH type="full" alt=".257 WBTY scoped.jpg"]385507[/ATTACH] [ATTACH type="full" alt=".257 WBTY scoped and suppressed.jpg"]385511[/ATTACH] [ATTACH type="full" alt="Bolt3.jpg"]385512[/ATTACH] The 145s can be a game changer for the .25 cal. [ATTACH type="full" alt="Black Hole 145 1 of 2.jpg"]385516[/ATTACH] G7 = .371 I took some measurements with the 145s; as seen below, CBTO touching the lands is 2.848" (average of 5) and COAL of 3.441"; I plan on starting at .020" off the lands as the baseline. I have plenty of magazine clearance. [/QUOTE]
