[QUOTE="Bart B, post: 563425, member: 5302"] That's a good thing. But Broughton should make accurate pressure measurements with strain gages then list load data; all in accordance with SAAMI standards. SAAMI test barrel's chamber and bore specs are different that Broughton's but if they provide these specs along with load data from standard pressure barrels, then folks will know for sure what loading data is accurate. Otherwise, 'cause the rest of us mortals are poor judges of pressure when it comes to reading case and primer deformations. And SAAMI pressure test barrel specs are based on conventional rifling with land and groove dimensions tightly specified dimensionally so Broughton's pressure test barrels should be also. [/QUOTE]
