Marlin recomends shooting Remington shells. I bought that same rifle and there was a coupon inside the box for $5 off your first box of shells from Remington. Remington now owns Marlin, so what else would Marlin recomend shooting?
120 grain amunition
Each weapon will exhibit a like for one or more brands. The only way to know is to assemble as many different brands/bullet weights as you can afford and shoot them.
Yes, you can shoot a slug from a Marlin Model 55, which is a shotgun designed for shooting slugs and buckshot. It is a smoothbore shotgun, making it suitable for firing rifled slugs. However, it's essential to ensure that the slug is compatible with the specific gauge of your Marlin Model 55 and to follow all safety guidelines when using it. Always check the manufacturer's recommendations for the best performance.
Due to the current lack of availability, you best shoot whatever you can find. Beyond that, CCI and Wolf make fine ammunition.

It's best to shoot in the corners and a little below the middle.
Read your manual, or request a free catalog from Marlin. Factory load is always what they recommend.
The best that I can do is say that your marlin model 783 was made between the years 1971-1988.
To the best of my knowledge No! Marlin has moved to North Carolina thou and Remington is still going strong.
Best would depend on intended use. Federal makes good 30-06 ammo. Soft point for hunting, FMJ for target use.
Depends on what your intended use is.
