I will give you my two cents worth of info, which you likely will ignore, but at least I will have said it.
1) Don't take it apart. They can be cleaned and lubricated nicely, just by using solvent and oil, and air pressure, If you have it.
I have a 1908 model 94 in 30-30, which has spent a lifetime on range work, carried in a saddle scabbard and I don't think a screw has ever been removed from the rifle. It functions and shoots perfectly.
Those early model 94 Winchester rifles are different than the later model pre 64 rifles. Just look at the configuration of screws behind the loading port. On the later years of the pre 64 model there are three screws in a triangle configuration. Yours will have two screws and a pin, in more of a right angle, than a triangle. The post 64s have two screws and a pin, but not in the same configuration as yours.
The post 64 models are easier to put back together than the usual pre 64 models and I will guess this one will be still trickier yet to get back together!
2) Don't bother, "working up a load," for a 30-30. Just load a standard load and shoot away.
