Impossable to say without you providing a serial number to your Model 30aw.
I believe that the marlin model 30AW(all weather) stock was a walnut finished birch stock.
Do you mean ejecting?
All that I can say is that the marlin model 336W/30AW were made during 1983-2007.Most of these were sold thru Wal-Mart.
NO! Your Marlin model 30aw(all weather) was chambered in 30-30Win.That is the only cartridge that will fire correctly in your rifle.
In 1983.
Its basically the Wal-Mart version of the Marlins.However there is nothing wrong with the gun at all,the only difference is the wood.Instead of having a Walnut Stock,it is just stained to match Walnut.So to answer your question AW stands for American Walnut stained...
100-300 USD
Look on the barrel and receiver.
prior to the year 2000 the marlin model 30AS was a way for marlin to distinguish that the rifle with the AS was a part of the glenfield line of guns,which were made with a walnut finished birch stock.The same applys to the AW except this also indicated all weather,meaning synthetic stock.
Your marlin should hold 5 plus one in the chamber.
I, too, have been trying to find out about the Marlin 30-30 Model 30AW and I discovered that the Model 30AW is the low priced version of the Model 336. (Very disappointing to pay $400 for a gun to find out it is a "low priced version".) Anyway, here is a link to the owners manual I found: http://www.marlinfirearms.com/pdfs/manuals/MFC_Centerfire.pdf It appears to be the same gun that I purchased.
