Ammo sheet TM 43-0001-27 states the following.
Bullet 62 grain SS109
Powder WC 26.1 grain
Velocity 3025 fps, 78 ft from muzzle
I read you where gonna use once fired LC cases, which is good. Use the heavier mil spec cases for ammo like this. But still, I would suggest starting 5 % under this load and work up if possible. That way working in the safest way possible.
Now read the disclaimer, I feel necessary to state
The above data comes from a military document and unfired cases are used to manufacture these rounds. The load is generally considered hot. So extreme caution is to be used if you decide to use this load in a handload.
