-I like to keep several extra primers handy and have found that they will fit very nicely in the small little triangles of the recoil pad of my encore
-I shoot polymer tipped bullets and made a brass bullet starter that screws to my ramrod I countersunk the end of it so that it will not deform the bullet. It is threaded so that I can also attach a cleaning jag to it without taking it off. It will also fit down the ramrod rings of my barrel and locks in nicely I then keep a spring loaded flip up t-handle attached to the muzzle end of the rod.
-My sling is made of an elastic type material and I have found that I can keep several dry patches and a short cleaning jag tucked between the two layers of elastic this eliminates fumbling through my possibles bag for the two things I need most before a reload.
These may all be things you all have already discovered or that you find to be useless but I thought I would share. Hopefully everyone else has something to add it might make for a very informative thread
