12 ga reloading Mec 650

[King Cobb]

I finally found a 650 of similar vintage(pre85) to my fathers at a favorable price.

It has been 20 years or so since I reloaded and the press I have found needs a new primer assembly.

Charge bar is labeled 12 ga 5 300.

I have a slew of 2.5 rst 12s both cheddite and paper as well as modern shells. Will have to play eith it on the length, have also been advised to try 2 inch shells in a parker.

Anyway any advise and or suggestions appreciated. I loaded a ton of 12 ga shells for my 1100 bavk when I shot skeet in 4-H so I am not a complete novice.
