In searching for belts for a 30-06, there seem to be a lot of different belts available, made by a number of different companies. Which work the best in the 1919a4?
any belt made for a 30 cal browning machine gun will work. try to find original equipment manufacturer for the least amount of headaches. anything made from 1930 - 1960 will probably work perfectly for you. there are new made options as well at IMA but some people have reported problems with them.
one thing you WILL need if you plan to run cloth is a belt loader. and the cost and expense of a cloth belt loader usually drives most people to links.
my advice - even though i prefer belts, i advise you start out with israeli .308 links. you can link any caliber with them by hand. they are cheap, and you can advance to cloth belts later
Why do some belts have metal tabs on both ends, while others have metal tabs on only one end?
double ended belts are able to be fed through the feedway without opening the top cover from either direction
single ended tabbed belts are able to fed into the feedway without opening the top cover on the tabbed end
some belts have eyelets on each end instead of tabs - you usually have to raise the top cover to load these belts which is no big deal.
I have read that you can wash some belts. I am very allergic to mold, musty smells, etc. Washing could be helpful for me, but how do you do that to something that old that has metal tabs?
just wash the things, but know its gonna cause them to shrink which will create havoc if you wash them new. run them through loaded a few times until they get too loose before you wash them. The cost of belts prevents me from washing my belts any other way than with woolite by hand in the sink. i worry about my $30.00 original ww2 belt fraying in the washing machine. i try to make them last as long as possible so i dont wash them until they just get too loose, and then i use woolite in the sink.
Do all belts have metal tabs? Can the tabs be detached?
no, not all belts have tabs - do not remove or detach the riveted tabs. it will cause the belt to fray and you will have just ruined an expensive belt
Do you need the tab to start feeding the belt into the gun?
the tab allows you to push it into the feedway of the gun and pul the cartridge into the feedway past the pawls. This prevents you from having to lift the top cover to load the belt. If you have a belt with no starter tab its a simple procedure of raising the top cover. placing the round under the extractor at the correct position and closing the top cover. Doing it this way prevents you from having to charge the gun twice to load a round. you do not need tabs.
They also make starter tabs for metal links. it is a long metal bar with a single loop in it. the browning metal links are designed to feed double loop into the gun first, and the starter tab attaches with its single loop to the double looped end of the browning link - you dont need these either, they just prevent you from having to raise your top cover
I think I have read of some people cutting a belt in the event of some gun malfunction. Are there misfire/other gun malfunction situations in which using links vs. a belt would be safer--in other words if you have to stop the gun feeding can you break the links easier vs. cutting the belt?
as stated, simply grab the belt and twist it which will prevent it from feeding and will immediately stop the gun. standard procedure for a runaway belt fed firearm using both cloth belts, or links.
unless you have a brass trunnion just use links. If you are allergic to mold, or musty smells or whatever just buy israeli .308 links - they work great and are easy to load by hand with no extra expensive tools needed
