Shot my gun for the first time today - I had loaded 50 rounds of ammo using once fired cases and CCI 400 primers - 35 Gr. Vmax bullets. I didn’t remove the staking of the primer pocket. Used a RCBS hand primer kit and when encountered a hard to seat primer just rotated the case and the primer would seat. Used True Blue power.
Results as follows:
6.0 grs – 1800, 1854, 1857, 1871, 1883 All primers were flat and cratered around the firing pin strike. Fired brass landed ahead to the right about 15 feet from gun.
6.2 grs – 1912, 1923, 18,62,1886, 1943 All primers as above. Fired brass went all over the place 20 feet away.
Factory SS196 S.R. – 1526,1594,1568, 1609 Primers normal and no bleeding around the strike area. Brass dropped 5 – 7 feet to right in same place. This is a real low load.
Used rest of rounds on targets.
Factory ammo shot first and groups around 4” – 6” inches.
6.0 grs. After shooting the above – got 1” – 1 ˝ “ groups from a rest. Same results from the 6.2” loads.
Conclusion: the SS196 S.R. is crap.
As I shot, the velocity became greater, the Bbl became hot, and the groups became smaller. I don’t think I would go over 6 grs. I have some 30 gr. Burger bullets on order and will load these with same powder and use 6. grs. I would expect higher vol.
With the right loads the gun is a tack driver…
I reloaded the cases tonight and saw no expansion to the primer pockets.
