Today I ran 50 fire forming loads for new ADG brass. The idea was to use up bullets and powder I don't like while fire forming.
Short action Mausingfield M7
Win. Staball 6.5
54.5 gr x 35
Norma Golden Target 130gr Advertised G1 .610 (I plugged in .585 to Strelok Pro) hit centered at 500.
Seated for max mag length 2.960 This shot the best @ .875" for 5 avg speed 3090
Seated 5 @ 2.947
Seated 5 @ 2.935
avg speed 3090
checked several five round groups for velocity out of the car rounds were cool 1st group avg 3090 SD 9.5, then 3115 SD 22, then 3085 SD16.2. Temp stability seems pretty good.
New ADG brass. Chamfer od/id & mandrel with .2625
CCI #34
26" Helix 6/ 8T Braked
9lb gun
3 x 5 round ladders with Berger 144 LRHT seated for max mag 2.960
Vit N565
57.4 = 2942 SD 11.2 1.1"
57.9 = 2972 SD 13.9 .875"
