You can make "speed loaders" for the Nylon 66 out of copper tubing. Get the size (3/8 in. IIRC) that just takes a 22rf cartridge. Block off one end by squeezing it in a vise and cut the tubing off just above where 14 rds will fit in. Then drill a hole cross-ways through the top to take a disposable stopper e.g. twist tie or twig, that keeps the bullets from falling out.
Make several dozen like that, load them up and carry them in a shoulder bag when you go in the woods. To load the gun, take out the magazine plunger stick and hold it and the rifle in one hand. Take the "speed loader" from the bag with the other hand, pull the stopper with your teeth, and pour the 14 bullets into the gun. Spit out stopper, insert and lock plunger stick, and shoot away. Repeat often.
It helps to have a 2 compartment bag to keep loaded and unloaded speed loaders separate.
