...some follow-up data of post-firing measurements taken of the brass. Measurements were taken of the loads listed above, but I'm only posting those from the max loads as the differences between the min & max loads were negligible (4th & 5th place decimal).
...Original Hornady die setting gave measurement's of Shoulder= 1.188 ; Base= 0.438 and cases trimmed to 1.480 ( the middle of the SAAMI max of 1.490, min of 1.470).
Bullet / Shoulder / Base / Powder
Nosler 70gn VG : 1.1932 , 0.441, 8208XBR
Nosler 105 RDF : 1.1938 , 0.441, W748
Berger 95 Classic Hunter : 1.194166667 , 0.4407 , LVR
Berger 95 VLD Hunting : 1.1940 , 0.441, LVR
Berger 105 VLD Target : 1.195166667, 0.441, LVR
HDY 108 ELDM : 1.195, 0.441, LVR
HDY 90 ELDX : 1.1935, 0.4415, LVR
HDY 87 VMAX : 1.194166667, 0.4415, LVR
Nosler 105 RDF : 1.194, 0.4415, LVR
My takeaway's are: I can now fine-tune my sizing die for more efficient shoulder bump. Negligible to zero brass flow affecting trim length. No measurable differences between the pre-annealed and non-annealed virgin brass I converted for their 1st firing. No differences in the cases that were fired with adjustable gas block closed completely to those when adjustable gas block opened for full functionality.
YMMV
