Took my S&W 4006 out to test fire some ammo I loaded up. Gun is new I am still breaking it in and adjusting the sights. This is the last target I used. Ammo stats : federal case. federal gold metal match primer, 180g fmj, 6.9 grains Hodgdon Longshot powder. I started with a charge of 6.5 grains worked my way up to 6.9 in 0.2 grain incriments. Hodgdon says max load is 8 grains on this recipe. 6.9 already feels rather snappy and do not think I will test higher than 7.5grains. Target range 25 yards.
